[0077] See also Figure 1 , Figure 1 The present invention provides a flowchart of a method for processing power increase or decrease of a nuclear power plant according to an embodiment of the present invention. The method for processing power increase or decrease of a nuclear power plant includes:

[0078] S11, when the enabling control is in a triggered state and the enabling signal meets a preset permission condition, in response to an execution instruction of the sequence execution control, a preset sequence control program corresponding to the sequence execution control is called; wherein the execution instruction carries a load adjustment amount for indicating a power increase or decrease;

[0079] S12, according to the execution instruction, adding the load adjustment amount to a plurality of preset sequence control instructions of the preset sequence control program, so that the preset sequence control instruction carries the load adjustment amount corresponding to the execution instruction;

[0080] S13. According to a plurality of sequence control program steps in the preset sequence control program, a plurality of preset sequence control instructions of the preset sequence control program are executed in sequence, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount.

[0081] It should be noted that the power increase and decrease processing method of the nuclear power plant is based on the distributed control system (DCS system) of the nuclear power plant, taking advantage of the controls and parameter display of the DCS system that can be repeatedly called, and realizing the one-key power increase and decrease operation of the DCS system by adding sequential control logic programs and the KIC screen of the special power plant computer information and control system. Among them, the configuration pages involved in the modification include the turbine regulation system (GRE), the centralized instrument and control equipment system (KCO), the main control room system (KSC), the rod control and rod position system (RGL), etc. The sequential control logic program design is based on the principle of not changing the operation process of the special operation sheet for manual power increase and decrease, not changing the original design function of the nuclear power plant, not changing the operator's operating habits, and not changing the logical order of the system program. The power increase and decrease processing method of the nuclear power plant is mainly to increase or decrease the power of the steam turbine unit slightly, and the power increase or decrease is generally within 10MW.

[0082] The processing system for power increase and decrease of the nuclear power plant includes an enabling control, a sequential control control and a plurality of sequential control execution controls. In the present embodiment, the controls in the processing method for power increase and decrease of the nuclear power plant adopt the "Permit" + "Execute" combined operation mode and the split controls are arranged independently, that is, a KC control (i.e., enabling control) is set to implement the "Permit" function; multiple KC controls (i.e., sequential control execution controls) are set respectively to implement the "Execute" function of increasing or decreasing power; a KG control (i.e., sequential control control) with a sequential control function is set to control the sequential control program, and the sequential control control is in an inoperable state. By activating the sequential control KG control by the KC control, the risk of misoperation by the operating operator can be effectively reduced, and the complexity of the operation is also reduced. When the working conditions require, the operator only needs to operate the enabling control and the sequential control execution control, and the program will be executed automatically without human intervention.

[0083] Specifically, the enable control is a permission control control for implementing the "Permit" function, that is, a control that allows or authorizes power increase or decrease operations; the sequence execution control is an execution control for increasing or decreasing power. The sequence execution controls can be set to multiple, which are used to indicate that the power is increased by a certain load adjustment amount or the power is reduced by a certain load adjustment amount. By splitting the controls, fine control of power increase and decrease can be achieved to avoid misoperation. In this embodiment, the number of sequence execution controls is not specifically limited. The enable control and the sequence execution control can be a button, a switch or other input device, which is not specifically limited in this embodiment. Figure 2 As shown, Figure 2 1 is a schematic diagram of a processing screen for power increase or decrease of a nuclear power plant provided by an embodiment of the present application. Figure 2 In the example, 803KC is the enable control (Permit), and 801KC, 802KC, 811KC, and 812KC are sequential control execution controls. Among them, the 801KC control is used to increase the power by 1MW, the 802KC control is used to increase the power by 2MW, the 811KC control is used to reduce the power by 1MW, and the 812KC control is used to reduce the power by 2MW. 804KC is used to indicate the termination control (STOP SGC).

[0084] The enable signal is a signal used to indicate that the preset sequence control program is allowed to start. When the enable control is triggered and the enable signal meets the preset permission conditions, the sequence control execution control is in a clickable state, thereby allowing the subsequent preset sequence control program to start. If the enable control is not triggered, or the enable signal does not meet the preset permission conditions, the sequence control execution control is in a non-clickable state, thereby preventing the operator from making an incorrect operation. Among them, the preset permission conditions are pre-set to determine whether the enable signal meets the requirements for executing subsequent programs. In this embodiment, the enable signal meets the preset permission conditions specifically including: the automatic control operation of the controller in the steam turbine regulation system of the power plant, the operation of the load controller, the non-operation of the interlocking mechanism, the no alarm condition of the steam turbine regulation system, the no alarm condition of the rod control / rod position system, and the power control rod is at the top of the stack.

[0085] An execution instruction is an instruction for instructing the execution of a specific operation, and the execution instruction carries a load adjustment for indicating the increase or decrease of power. The load adjustment is the load value at which the power is to be increased or decreased, wherein the load adjustment can be specifically set according to the actual situation. A sequence control program is usually a sequence control logic that executes a series of instructions in a specific order in an automated control system to complete a task or reach a certain state. The preset sequence control program is a pre-set sequential control logic for controlling the power of a nuclear power plant to increase or decrease. The preset sequence control program includes a plurality of pre-set preset sequence control instructions and sequence control program steps. A preset sequence control instruction refers to a single instruction or step in a preset sequence control program, and a sequence control program step sequence refers to the execution order of instructions or steps in a preset sequence control program. The power adjustment of a nuclear power plant is achieved by executing in the order of the preset sequence control instructions, i.e., the sequence control program step sequence.

[0086] In this embodiment, when the enable control is triggered and the enable signal meets the preset permission conditions, the sequence control execution control is triggered, and according to the execution instruction of the sequence control execution control, its corresponding preset sequence control program is called, and the load adjustment amount in the execution instruction is added to the preset sequence control program, so that each preset sequence control instruction carries the load adjustment amount, and according to the load adjustment amount, a series of preset sequence control instructions are executed according to multiple sequence control program steps, thereby realizing the increase or decrease of the nuclear power plant power.

[0087] It can be understood that the processing method for power increase and decrease of a nuclear power plant provided by the embodiment of the present application is that when the enable control is in a triggered state and the enable signal meets the preset permission condition, in response to the execution instruction of the sequential control execution control, the preset sequential control program corresponding to the sequential control execution control is called; wherein the execution instruction carries a load adjustment amount for indicating power increase or decrease; according to the execution instruction, the load adjustment amount is added to multiple preset sequential control instructions of the preset sequential control program, so that the preset sequential control instruction carries the load adjustment amount corresponding to the execution instruction; then, according to the multiple sequential control program steps in the preset sequential control program, the multiple preset sequential control instructions of the preset sequential control program are executed in sequence, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount. By converting the power increase and decrease operation of the nuclear power plant from the original manual operation required by the operator for multiple times to a one-button operation controlled by the automatic sequential control logic program, the switching frequency of the operation screen and the number of operations of the operator can be reduced, thereby improving the operation efficiency and reducing the probability of human error risk.

[0088] In a possible implementation, the preset sequence control program includes a first preset sequence control program and a second preset sequence control program, wherein the first preset sequence control program and the second preset sequence control program both include a plurality of preset sequence control instructions;

[0089] In response to the execution instruction of the sequence execution control, calling the preset sequence control program corresponding to the sequence execution control includes:

[0090] When the execution instruction carries a load adjustment amount for indicating power reduction, according to the execution instruction, a first preset sequence control program is called from a plurality of preset sequence control programs controlled by the sequence control component to start the first preset sequence control program to perform a power reduction operation of the nuclear power plant;

[0091] Accordingly, according to the multiple sequence control program steps in the preset sequence control program, the multiple preset sequence control instructions of the preset sequence control program are executed in sequence, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount, including:

[0092] According to the plurality of sequence control program steps in the first preset sequence control program, the plurality of preset sequence control instructions of the first preset sequence control program are executed in sequence, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount;

[0093] When the execution instruction carries a load adjustment amount for indicating a power increase, according to the execution instruction, a second preset sequence control program is called from a plurality of preset sequence control programs controlled by the sequence control component to start the second preset sequence control program to perform a power increase operation of the nuclear power plant;

[0094] Accordingly, according to the multiple sequence control program steps in the preset sequence control program, the multiple preset sequence control instructions of the preset sequence control program are executed in sequence, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount, including:

[0095] According to a plurality of sequence control program steps in the second preset sequence control program, a plurality of preset sequence control instructions of the second preset sequence control program are executed in sequence, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount.

[0096] It should be noted that the first preset sequential control program is a preset program for reducing the power of a nuclear power plant; and the second preset sequential control program is a preset program for increasing the power of a nuclear power plant.

[0097] The sequence control is used to control multiple preset sequence programs. The sequence control can select and execute the appropriate preset sequence program according to the current execution instruction. The sequence control is in an inoperable state.

[0098] When the sequence control execution control is triggered and its execution instruction carries a load adjustment amount for indicating power reduction, at this time, the sequence control control calls the first preset sequence control program from the multiple preset sequence control programs it controls according to the load adjustment amount in the execution instruction, starts the first preset sequence control program, and executes the multiple preset sequence control instructions of the first preset sequence control program according to the multiple sequence control program steps in the first preset sequence control program, that is, performs a series of operations according to the preset steps and order in the first preset sequence program, so that the power of the nuclear power plant is reduced according to the load adjustment amount.

[0099] When the sequence control execution control is triggered and its execution instruction carries a load adjustment amount for indicating a power increase, the sequence control control calls a second preset sequence program from multiple preset sequence programs it controls according to the load adjustment amount in the execution instruction, starts the second preset sequence program, and executes multiple preset sequence instructions of the second preset sequence program according to the multiple sequence program steps in the second preset sequence program, that is, performs a series of operations according to the preset steps and order in the second preset sequence program, so that the power of the nuclear power plant is increased according to the load adjustment amount.

[0100] It can be understood that by triggering the sequential control execution control and selecting and calling the corresponding preset sequential control program according to the load adjustment amount in the execution instruction, the power of the nuclear power plant can be increased or decreased safely and effectively, which not only improves the operating efficiency and safety of the nuclear power plant, but also reduces the potential risks brought by human operation.

[0101] In a possible implementation, the plurality of preset sequence control instructions of the first preset sequence control program include a first power reduction sequence control instruction, a second power reduction sequence control instruction, a third power reduction sequence control instruction, a sixth power reduction sequence control instruction, and a seventh power reduction sequence control instruction;

[0102] When the first preset sequence control program is in the startup state, multiple sequence control program instructions of the first preset sequence control program are executed in sequence according to multiple sequence control program steps in the first preset sequence control program, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount, including:

[0103] In response to the first power reduction sequential control instruction, instructing the load lifting controller program to exit by closing the load lifting controller control;

[0104] In response to the second power reduction sequential control instruction, according to the load adjustment amount and the preset rate setting condition, the load increase and decrease rate parameter is set to a first rate corresponding to the load adjustment amount;

[0105] In response to a third power reduction sequential control instruction, setting a first target load according to the current load and the load adjustment amount;

[0106] When it is determined that the current correction factor reaches the first target correction factor value, in response to the sixth power reduction sequential control instruction, the load increase / decrease controller program is instructed to start by opening the load increase / decrease controller control, and the power reduction operation is performed to reduce the power of the nuclear power plant to the first target load; wherein the first target correction factor value is determined according to the load adjustment amount and the preset correction factor setting condition;

[0107] In response to the seventh power reduction sequential control instruction, the load lifting and lowering controller control is turned off, and the sequential control execution control corresponding to the first preset sequential control program is reset.

[0108] It should be noted that if Figure 3 As shown, Figure 3 This is a flowchart of the start-up of the first preset sequence control program provided by an embodiment of the present application. The multiple preset sequence control instructions of the first preset sequence control program include a first power reduction sequence control instruction, a second power reduction sequence control instruction, a third power reduction sequence control instruction, a sixth power reduction sequence control instruction, and a seventh power reduction sequence control instruction; these preset sequence control instructions are all instructions for indicating power reduction operations in the first preset sequence control program, and each instruction corresponds to a sequence control program step. Figure 3 The specific process of starting the first preset sequence program is as follows:

[0109] When the first preset sequence control program is started, relevant instructions are issued to control relevant controls in sequence, that is, the first power reduction sequence control instruction (corresponding to STEP21), the second power reduction sequence control instruction (corresponding to STEP22), the third power reduction sequence control instruction (corresponding to STEP23), the sixth power reduction sequence control instruction (corresponding to STEP26) and the seventh power reduction sequence control instruction (corresponding to STEP27) are executed in sequence.

[0110] STEP21: In response to the first power reduction sequential control instruction, the load lifting controller program is instructed to exit by closing the load lifting controller control. That is, the first power reduction sequential control instruction sets the Program Device control that controls the load lifting controller program to OFF, and instructs the load lifting controller program to exit. At this time, the first power reduction sequential control instruction lasts for a certain period of time. In this embodiment, the duration of the first power reduction sequential control instruction can be 5s. Among them, the load lifting controller control is a control for controlling the start and stop of the load lifting controller program. The load lifting controller control can be a button, a switch or other form of input device. The load lifting controller program is a program for controlling the power increase and decrease of the nuclear power plant turbine according to the state of the load lifting controller control. When the load lifting controller control is turned on, the load lifting controller program will start and perform the corresponding power increase and decrease operation; when the load lifting controller control is turned off, the load lifting controller program will exit to ensure that other power adjustment programs, i.e., the load lifting controller program, are not running before the power reduction operation begins.

[0111] STEP22: In response to the second power reduction sequential control instruction, according to the load adjustment amount and the preset rate setting condition, the load lifting rate parameter is set to the first rate corresponding to the load adjustment amount. That is, according to the load adjustment amount and the preset rate setting condition, the load lifting rate parameter is set. At this time, the second power reduction sequential control instruction sets the LoadGrd AC control that sets the load lifting rate parameter to the corresponding load lifting rate, that is, the first rate. At this time, the second power reduction sequential control instruction lasts for a certain period of time. It should be noted that the preset rate setting condition is a preset rate of load lifting and lowering. The load lifting rate parameter is a numerical value used to control the speed of power lifting and lowering. In this embodiment, the rate of power increase of 1MW or 2MW and power reduction of 1MW or 2MW can both be 1MW / min. In this embodiment, the specific value of the load lifting rate parameter is not limited.

[0112] STEP23: In response to the third power reduction sequential control instruction, set the first target load according to the current load and the load adjustment amount. That is, the first target load is set according to the current load and the load adjustment amount. The third power reduction sequential control instruction sets the TARGET LOAD AC control that sets the target load to the first target load. The first target load is the target load determined by the current load and the load adjustment amount during the power reduction operation of the nuclear power plant. At this time, the third power reduction sequential control instruction lasts for a certain period of time, and then it is necessary to wait for the first preset time period before executing the sixth power reduction sequential control instruction to ensure that the sequential control program sequence is completed. Among them, the first preset time period can be 5s. In this embodiment, the first preset time period is not specifically limited.

[0113] STEP26: When it is determined that the current correction factor reaches the first target correction factor value, in response to the sixth power reduction sequential control instruction, the load lifting controller program is instructed to start by opening the load lifting controller control, and the power reduction operation is performed to reduce the power of the nuclear power plant to the first target load. That is, when the current correction factor reaches the target correction factor value, the sixth power reduction sequential control instruction sets the Program Device control to ON, turns on the load lifting controller control, puts the load lifting controller program into operation, and performs power reduction adjustment on the nuclear power plant until the power of the nuclear power plant is reduced to the first target load. Among them, the preset correction factor setting condition is a pre-set condition for determining the required correction factor parameters. The first target correction factor value is a parameter used to adjust the power reduction process determined according to the load adjustment amount and the preset correction factor setting condition during the power reduction operation of the nuclear power plant. This value is used to ensure the accuracy and stability of the operation. In this embodiment, the preset correction factor setting condition can be: target load + target correction factor value = 1088MW, and the target correction factor value is not less than 0. At this time, the sixth power reduction sequential control instruction lasts for a certain period of time. Then, it is necessary to wait for the second preset time period before executing the seventh power reduction sequential control instruction to ensure that the sequential control program sequence is completed. The second preset time period may be 130 seconds. In this embodiment, the second preset time period is not specifically limited.

[0114] STEP27: In response to the seventh power reduction sequential control instruction, the load lifting controller control is turned off, and the sequential control execution control corresponding to the first preset sequential control program is reset. That is, after completing the power reduction operation, the seventh power reduction sequential control instruction sets the Program Device control to OFF, turns off the load lifting controller control, and exits the load lifting controller program. At this time, the first preset sequential control program ends and the sequential control execution control is reset.

[0115] It should be noted that when executing each power reduction sequential control instruction, each instruction needs to last for a certain period of time to ensure that each power reduction sequential control instruction is received by the corresponding control and completes each step. In this embodiment, the duration can be 5s, and in this embodiment, there is no specific limitation on this. The first preset time period and the second preset time period are to avoid the situation where the next sequential control program step is started before the previous sequential control program step is completed. In this embodiment, there is no specific limitation on the first preset time period and the second preset time period. In this embodiment, the Program Device control is a control for controlling the start and stop of the load lifting and lowering controller program; the Load Grd AC control is a control for setting the load lifting and lowering rate parameters to control the load lifting and lowering rate; the TARGET LOAD AC control is a control for controlling the load to be reduced to the target load.

[0116] In a possible implementation, the plurality of preset sequence control instructions of the first preset sequence control program further include a fourth power reduction sequence control instruction and a fifth power reduction sequence control instruction;

[0117] After setting the first target load and before responding to the sixth power reduction sequential control instruction, the method for processing power increase or decrease of the nuclear power plant includes:

[0118] In response to a fourth power reduction sequential control instruction, determining a first target correction factor value according to a load adjustment amount and a preset correction factor setting condition, and setting a required correction factor parameter as the first target correction factor value;

[0119] When it is determined that the set first target correction factor value meets the preset correction factor condition, in response to the fifth power reduction sequential control instruction, the first target correction factor value is effective.

[0120] It should be noted that if Figure 4 As shown, Figure 4 It is a flowchart diagram of starting a first preset sequence control program provided by another embodiment of the present application. Figure 4 In the embodiment, the plurality of preset sequence control instructions of the first preset sequence control program further include a fourth power reduction sequence control instruction and a fifth power reduction sequence control instruction, namely, a fourth power reduction sequence control program instruction (corresponding to STEP24) and a fifth power reduction sequence control program instruction (corresponding to STEP25).

[0121] Following the above example, after setting the first target load (i.e., step STEP23) and before responding to the sixth power reduction sequence control instruction (i.e., step STEP26), it is also necessary to execute the fourth power reduction sequence control program instruction (corresponding to STEP24) and the fifth power reduction sequence control program instruction (corresponding to STEP25), that is:

[0122] STEP24: In response to the fourth power reduction sequential control instruction, determine the first target correction factor value according to the load adjustment amount and the preset correction factor setting condition, and set the required correction factor parameter to the first target correction factor value. That is, the required first target correction factor value is set, and the fourth power reduction sequential control instruction modifies the correction factor value of the RGL007KU control according to the load adjustment amount and the preset correction factor setting condition. At this time, the fourth power reduction sequential control instruction will last for a certain period of time, and then it is necessary to wait for the first preset time period before executing the fifth power reduction sequential control instruction to ensure the completion of the sequential control program sequence. Among them, the first preset time period can be 5s. The preset correction factor setting condition is a pre-set condition for determining the required correction factor parameter. The first target correction factor value is a parameter used to adjust the power reduction process determined according to the load adjustment amount and the preset correction factor setting condition during the power reduction operation of the nuclear power plant. This value is used to ensure the accuracy and stability of the operation. In this embodiment, the preset correction factor setting condition can be: target load + target correction factor value = 1088MW, and the target correction factor value is not less than 0.

[0123] STEP25: When it is determined that the set first target correction factor value meets the preset correction factor conditions, respond to the fifth power reduction sequential control instruction and take effect on the first target correction factor value. That is, after confirming that the correction factor value has been set according to the preset correction factor conditions, the fifth power reduction sequential control instruction takes effect on the RGL007KC control to make the first target correction factor value effective. At this time, the fifth power reduction sequential control instruction will last for a certain period of time, and then it is necessary to wait for the first preset time period before executing the sixth power reduction sequential control instruction to ensure the completion of the sequential control program sequence. Among them, the first preset time period can be 5s. In this embodiment, the first preset time period is not specifically limited. Among them, the RGL007KU control is a control for setting the target correction factor value; the RGL007KC control is a control for taking effect on the target correction factor value.

[0124] Continuing with the above example, in actual applications, the control process of the sequence control program for reducing the power of a nuclear power plant by 1MW is as follows: When the operator clicks the sequence control execution control corresponding to reducing the power by 1MW, the first preset sequence control program starts and issues instructions to control the relevant controls in sequence. At this time, the load adjustment amount is -1MW. The first step is to exit the load lifting and lowering controller, set the Program Device control to OFF, and the instructions issued by the first preset sequence control program last for 5s. The second step is to set the load lifting and lowering rate, set the Load GrdAC control to 1MW / min, and the instructions issued by the first preset sequence control program last for 5s. The third step is to set the target load; set the TARGET LOAD AC control to the current load -1MW, the instructions issued by the first preset sequence control program last for 5s, and then wait for 5s. The fourth step is to set the required correction factor parameters, modify the target correction factor value of the RGL007KU control, and the instructions issued by the first preset sequence control program last for 5s, and then wait for 5s. The fifth step is to take effect on the set target correction factor value, that is, to take effect on the RGL007KC control, and the instructions issued by the first preset sequence control program last for 5s, and then wait for 5s. Step 6: Set the Program Device control to ON, put the load lifting controller into operation, the command issued by the first preset sequence control program lasts for 5 seconds, and then wait for 130 seconds to ensure that the power reduction of 1MW has been completed. Step 7: Exit the load lifting controller, set the Program Device control to OFF, the command issued by the first preset sequence control program lasts for 5 seconds, the sequence control ends, and the sequence control execution control is reset.

[0125] In a possible implementation, the plurality of preset sequence control instructions of the second preset sequence control program include a first power increase sequence control instruction, a second power increase sequence control instruction, a third power increase sequence control instruction, a fourth power increase sequence control instruction, a fifth power increase sequence control instruction, and an eighth power increase sequence control instruction;

[0126] When the second preset sequence control program is in the startup state, according to the plurality of sequence control program steps in the second preset sequence control program, the plurality of sequence control program instructions of the second preset sequence control program are sequentially executed to make the power of the nuclear power plant rise and fall according to the load adjustment amount, including:

[0127] In response to the first power increase sequential control instruction, instructing the load increase / decrease controller program to exit by turning off the load increase / decrease controller control;

[0128] In response to the second power increase sequential control instruction, according to the load adjustment amount and the preset rate setting condition, the load increase and decrease rate parameter is set to a second rate corresponding to the load adjustment amount;

[0129] In response to the third power increase sequential control instruction, setting a second target load according to the current load and the load adjustment amount;

[0130] In response to a fourth power increase sequential control instruction, instructing the load increase / decrease controller program to start by turning on the load increase / decrease controller control, and executing a power increase operation to increase the power of the nuclear power plant to a second target load;

[0131] In response to the fifth power increase sequential control instruction, the load increase and decrease controller control is turned off;

[0132] When it is determined that the current correction factor reaches the second target correction factor value, in response to the eighth power increase sequential control instruction, the sequential control execution control corresponding to the second preset sequential control program is reset; wherein the second target correction factor value is determined based on the load adjustment amount and the preset correction factor setting conditions.

[0133] It should be noted that if Figure 5 As shown, Figure 5 It is a flowchart of the start-up of the second preset sequence control program provided by an embodiment of the present application. The multiple preset sequence control instructions of the second preset sequence control program include the first power increase sequence control instruction, the second power increase sequence control instruction, the third power increase sequence control instruction, the fourth power increase sequence control instruction, the fifth power increase sequence control instruction and the eighth power increase sequence control instruction; these preset sequence control instructions are all instructions for indicating the power increase operation in the second preset sequence control program, and each instruction corresponds to a sequence control program step. Figure 3 The specific process of starting the second preset sequence program is as follows:

[0134] When the second preset sequence control program is started, relevant instructions are issued to control relevant controls in sequence, that is, the first power increase sequence control instruction (corresponding to STEP31), the second power increase sequence control instruction (corresponding to STEP32), the third power increase sequence control instruction (corresponding to STEP33), the fourth power increase sequence control instruction (corresponding to STEP34), the fifth power increase sequence control instruction (corresponding to STEP35) and the eighth power increase sequence control instruction (corresponding to STEP38) are executed in sequence.

[0135] STEP31: In response to the first power increase sequential control instruction, the load increase and decrease controller program is instructed to exit by closing the load increase and decrease controller control. That is, the first power increase sequential control instruction sets the Program Device control that controls the load increase and decrease controller program to OFF, and instructs the load increase and decrease controller program to exit. At this time, the first power increase sequential control instruction lasts for a certain period of time. In this embodiment, the duration of the first power increase sequential control instruction can be 5s. Among them, the load increase and decrease controller control is a control for controlling the start and stop of the load increase and decrease controller program. The load increase and decrease controller control can be a button, a switch or other form of input device. The load increase and decrease controller program is a program for controlling the power increase and decrease of the nuclear power plant turbine according to the state of the load increase and decrease controller control. When the load increase and decrease controller control is turned on, the load increase and decrease controller program will start and perform the corresponding power increase and decrease operation; when the load increase and decrease controller control is turned off, the load increase and decrease controller program will exit to ensure that other power adjustment programs, i.e., the load increase and decrease controller programs, are not running before the power reduction operation begins.

[0136] STEP32: In response to the second power increase sequential control instruction, according to the load adjustment amount and the preset rate setting condition, the load increase and decrease rate parameter is set to the second rate corresponding to the load adjustment amount. That is, according to the load adjustment amount and the preset rate setting condition, the load increase and decrease rate parameter is set. At this time, the second power increase sequential control instruction sets the LoadGrd AC control that sets the load increase and decrease rate parameter to the corresponding load increase and decrease rate, that is, the second rate. At this time, the second power increase sequential control instruction lasts for a certain period of time. It should be noted that the preset rate setting condition is a preset rate of load increase and decrease. The load increase and decrease rate parameter is a numerical value used to control the speed of power increase and decrease. In this embodiment, the rate of power increase of 1MW or 2MW and power reduction of 1MW or 2MW can both be 1MW / min. In this embodiment, the specific value of the load increase and decrease rate parameter is not limited.

[0137] STEP33: In response to the third power increase sequential control instruction, set the second target load according to the current load and the load adjustment amount. That is, the second target load is set according to the current load and the load adjustment amount. The third power increase sequential control instruction sets the TARGET LOAD AC control that sets the target load to the second target load. The second target load is the target load determined by the current load and the load adjustment amount during the power increase operation of the nuclear power plant. At this time, the third power increase sequential control instruction lasts for a certain period of time, and then it is necessary to wait for the third preset time period before executing the fourth power increase sequential control instruction to ensure that the sequential control program sequence is completed. Among them, the third preset time period can be 5s. In this embodiment, the third preset time period is not specifically limited.

[0138] STEP34: In response to the fourth power increase sequential control instruction, the load increase and decrease controller program is instructed to start by turning on the load increase and decrease controller control, and the power increase operation is performed to increase the power of the nuclear power plant to the second target load. That is, after setting the second target load, the fourth power increase sequential control program instruction sets the Program Device control to ON, turns on the load increase and decrease controller control, and puts the load increase and decrease controller program into operation to increase the power of the nuclear power plant until the power of the nuclear power plant is increased to the second target load. At this time, the fourth power increase sequential control program instruction lasts for a certain period of time. Then, it is necessary to wait for the fourth preset time period before executing the fifth power increase sequential control instruction to ensure that the sequential control program sequence is completed. Among them, the fourth preset time period can be 130s. In this embodiment, the fourth preset time period is not specifically limited.

[0139] STEP35: In response to the fifth power increase sequence control instruction, the load lifting controller control is turned off. That is, after completing the power increase operation, the fifth power increase sequence control program instruction sets the Program Device control to OFF, turns off the load lifting controller control, and exits the load lifting controller program. At this time, the fifth power increase sequence control instruction lasts for a certain period of time. Then, it is necessary to wait for the third preset time period before executing the eighth power increase sequence control instruction to ensure that the sequence control program step is completed.

[0140] STEP38: When it is determined that the current correction factor reaches the second target correction factor value, in response to the eighth power increase sequence control instruction, the sequence control execution control corresponding to the second preset sequence control program is reset. Among them, the preset correction factor setting condition is a pre-set condition for determining the required correction factor parameters. The second target correction factor value is a parameter used to adjust the power increase process determined according to the load adjustment amount and the preset correction factor setting condition during the power increase operation of the nuclear power plant. This value is used to ensure the accuracy and stability of the operation. In this embodiment, the preset correction factor setting condition can be: target load + target correction factor value = 1088MW, and the target correction factor value is not less than 0.

[0141] It should be noted that when executing each power-up sequence program instruction, each instruction needs to last for a certain period of time to ensure that each power-up sequence program instruction is received by the corresponding control and executes each step. In this embodiment, the duration can be 5s, and in this embodiment, there is no specific limitation on this. The third preset time period and the fourth preset time period are to avoid the situation where the next sequence program step is executed before the previous sequence program step is completed. In this embodiment, there is no specific limitation on the third preset time period and the fourth preset time period. In this embodiment, the Program Device control is a control for controlling the start and stop of the load lifting controller program; the Load Grd AC control is a control for setting the load lifting rate parameters to control the load lifting rate; the TARGET LOAD AC control is a control for controlling the load to be reduced to the target load.

[0142] In a possible implementation, the plurality of preset sequence control instructions of the second preset sequence control program further include a sixth power increase sequence control instruction and a seventh power increase sequence control instruction;

[0143] After the load increase / decrease controller is turned off and before responding to the eighth power increase sequence control instruction, the power increase / decrease processing method of the nuclear power plant includes:

[0144] In response to the sixth power increase sequential control instruction, determining a second target correction factor value according to the load adjustment amount and a preset correction factor setting condition, and setting the required correction factor parameter as the second target correction factor value;

[0145] When it is determined that the set second target correction factor value meets the preset correction factor condition, the second target correction factor value is effective in response to the seventh power increase sequential control instruction.

[0146] It should be noted that if Figure 6 As shown, Figure 6 It is a flowchart diagram of starting a second preset sequence control program provided by another embodiment of the present application. Figure 6 In the example above, after the load lifting controller is turned off (corresponding to STEP35), and before responding to the eighth power raising sequence control instruction (corresponding to STEP38), the sixth power raising sequence control instruction (corresponding to STEP36) and the seventh power raising sequence control instruction (corresponding to STEP37) need to be executed, that is:

[0147] STEP36: In response to the sixth power increase sequential control instruction, determine the second target correction factor value according to the load adjustment amount and the preset correction factor setting condition, and set the required correction factor parameter to the second target correction factor value. That is, the required second target correction factor value is set, and the sixth power increase sequential control instruction modifies the correction factor value of the RGL007KU control according to the load adjustment amount and the preset correction factor setting condition. At this time, the sixth power increase sequential control instruction will last for a certain period of time, and then it is necessary to wait for the third preset time period before executing the seventh power increase sequential control instruction to ensure the completion of the sequential control program sequence. Among them, the third preset time period can be 5s. The preset correction factor setting condition is a pre-set condition for determining the required correction factor parameter. The second target correction factor value is a parameter used to adjust the power increase process determined according to the load adjustment amount and the preset correction factor setting condition during the power increase operation of the nuclear power plant. This value is used to ensure the accuracy and stability of the operation. In this embodiment, the preset correction factor setting condition can be: target load + target correction factor value = 1088MW, and the target correction factor value is not less than 0.

[0148] STEP37: When it is determined that the set second target correction factor value meets the preset correction factor conditions, respond to the seventh power increase sequential control instruction and take effect on the second target correction factor value. That is, after confirming that the correction factor value has been set according to the preset correction factor conditions, the seventh power increase sequential control instruction takes effect on the RGL007KC control to make the second target correction factor value effective. At this time, the seventh power increase sequential control instruction will continue for a certain period of time, and then it is necessary to wait for the third preset time period before executing the eighth power increase sequential control instruction to ensure the completion of the sequential control program sequence. Among them, the third preset time period can be 5s. Among them, the RGL007KC control is a control for taking effect on the target correction factor value.

[0149] Continuing with the above example, in actual applications, the control process of the sequence control program for increasing the power of a nuclear power plant by 1MW is as follows: When the operator clicks the sequence control execution control corresponding to the 1MW power increase, the second preset sequence control program starts and issues instructions to control the relevant controls in sequence. At this time, the load adjustment amount is +1MW. Step 1: Exit the load lifting and lowering controller, set the Program Device control to OFF, and the instructions issued by the second preset sequence control program last for 5s. Step 2: Set the load lifting and lowering rate, set the Load GrdAC control to 1MW / min, and the instructions issued by the second preset sequence control program last for 5s. Step 3: Set the target load; set the TARGET LOAD AC control to the current load +1MW, the instructions issued by the second preset sequence control program last for 5s, and then wait for 5s. Step 4: Set the Program Device control to ON, put the load lifting and lowering controller into operation, the instructions issued by the second preset sequence control program last for 5s, and then wait for 130s to ensure that the power increase of 1MW has been completed. Step 5: Exit the load lifting and lowering controller, set the Program Device control to OFF, and the instructions issued by the second preset sequence control program last for 5s. Step 6: Set the required correction factor parameters, modify the target correction factor value of the RGL007KU control, the second preset sequence control program sends the command for 5 seconds, and then wait for 5 seconds. Step 7: Validate the set target correction factor value, that is, validate the RGL007KC control, the second preset sequence control program sends the command for 5 seconds, and then wait for 5 seconds. Step 8: The sequence control ends, and the sequence control execution control is reset.

[0150] In a possible implementation, in the process of sequentially executing a plurality of preset sequence control instructions of the preset sequence control program according to a plurality of sequence control program steps in the preset sequence control program so as to increase or decrease the power of the nuclear power plant according to the load adjustment amount, the method for processing power increase or decrease of the nuclear power plant further includes:

[0151] When it is detected that the enable signal does not meet the preset permission condition, a first termination instruction is generated;

[0152] According to the first termination instruction, the preset sequence control program corresponding to the sequence control execution control is terminated and the load lifting controller control is closed.

[0153] It should be noted that the preset permission condition is a pre-set judgment on whether the enable signal meets the requirements for executing subsequent programs. The first termination instruction is an emergency stop signal automatically generated when the enable signal does not meet the preset permission condition, which is used to instruct the termination of the current preset sequence control program. During the execution of the preset sequence control program, if there is an enable signal that does not meet the preset permission condition, it indicates that there is an abnormal situation or risk at this time, and the first termination instruction will be automatically generated to terminate the preset sequence control program corresponding to the sequence execution control, and turn off the load lifting controller control to exit the load lifting controller. By automatically generating the first termination instruction, terminating the preset sequence control program and turning off the load lifting controller control, potential risks and damages can be prevented, thereby improving the safety and reliability of nuclear power plant operation and ensuring the safety of personnel and equipment.

[0154] In a possible implementation, the method for processing power increase or decrease of the nuclear power plant further includes:

[0155] In response to the second termination instruction of the termination control, the preset sequence control program corresponding to the sequence control execution control is terminated.

[0156] It should be noted that the termination control is a control used to manually trigger the termination of a preset sequence control program. The termination control can be an emergency stop button, switch or other form of input device. The second termination instruction is an emergency stop signal generated when the operator manually triggers the termination control to indicate the termination of the current preset sequence control program. Different from the first termination instruction, the second termination instruction is generated by the operator triggering the termination control. Figure 2 As shown in , 804KC represents the termination control, i.e., stop SGC. At the same time, the termination control also sends a signal to close the load lifting controller control.

[0157] When receiving the second termination instruction of the termination control, the system will immediately terminate the preset sequence control program associated with the sequence execution control and return the system to a safe state. That is, in an emergency, the operator can stop the current power increase or decrease operation by manually triggering the termination control, thereby avoiding potential risks or damage. Combining the manual termination kinetic energy with the automatic termination function provides comprehensive safety protection for nuclear power plants.

[0158] In a possible implementation, before responding to the execution instruction of the sequential control execution control, the method for processing power increase or decrease of the nuclear power plant includes:

[0159] According to the fact that the controller in the nuclear power plant's steam turbine regulation system is automatically controlled and in operation, the load controller is in operation, the interlocking mechanism is not in operation, there is no alarm in the steam turbine regulation system, there is no alarm in the rod control / rod position system, and the power control rod is at the top of the stack, it is determined that the enable signal meets the preset permission conditions.

[0160] It should be noted that the enabling information satisfies the preset permission conditions, including: the controller in the steam turbine regulation system of the power plant is automatically controlled and put into operation, the load controller is put into operation, the interlocking mechanism is not put into operation, there is no alarm in the steam turbine regulation system, there is no alarm in the rod control / rod position system, and the power control rod is at the top of the reactor. Among them, the controller in the steam turbine regulation system is the core component used to adjust the operating state of the steam turbine in the steam turbine regulation system. The automatic control operation of the controller means that the controller has automatically adjusted the steam turbine according to the preset parameters and logic. The load controller is an important part of the steam turbine regulation system for adjusting the output power of the steam turbine according to the load demand. The load controller is put into operation means that the load controller has started to adjust the output power of the steam turbine according to the preset parameters and logic according to the load demand. The interlocking mechanism refers to a safety control mechanism to prevent potential risks from occurring. By means of mutual constraints, it ensures that different parts of the system can be carried out in a predetermined order, thereby avoiding unsafe or conflicting situations. The rod control / rod position system is used to control the power control rods in the reactor to adjust the power and reactivity of the reactor. The power control rod is used to adjust the power of the reactor. The power control rods are at the top of the reactor when the power control rods are fully or partially withdrawn from the reactor, thereby reducing the reaction rate and power output of the reactor.

[0161] In the steam turbine regulation system of a nuclear power plant, when the controller automatic control is in operation, the load controller is in operation, the interlocking mechanism is not in operation, the steam turbine regulation system has no alarm, the rod control / rod position system has no alarm, and the power control rod is at the top of the pile, it can be determined that these enable signals meet the preset permission conditions.

[0203] Corresponding to a method for processing power increase or decrease of a nuclear power plant in the above embodiment, Figure 8 A schematic diagram of the structure of a nuclear power plant power ramp processing system provided in one embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment of the present application are shown.

[0204] Reference Figure 8 The nuclear power plant power increase and decrease processing system 3 of this embodiment includes:

[0205] An enabling control 31, a sequence control control 32 and a plurality of sequence execution controls 33#i (where i represents the serial number of the sequence execution control 33#i; i=1, 2, ..., n, n is a natural number; n represents the number of the sequence execution controls 33#i); wherein,

[0206] An enabling control 31, used to activate a plurality of sequential control execution controls 33#i and a sequential control control control 32 when triggered by an operator and the enabling signal satisfies a preset permission condition;

[0207] The sequence control execution control 33#i is used to send an execution instruction to the sequence control control 32 when triggered by the operator, so that the sequence control control 32 calls the preset sequence control program corresponding to the sequence control execution control 33#i; wherein the execution instruction carries a load adjustment amount for indicating power increase or decrease;

[0208] The sequence control component 32 is used to start the preset sequence control program corresponding to the sequence control execution control 33#i in response to the execution instruction of the sequence control execution control 33#i when the sequence control execution control 33#i is in the triggered state; according to the execution instruction, add the load adjustment amount to the multiple preset sequence control instructions of the preset sequence control program, so that the preset sequence control instruction carries the load adjustment amount corresponding to the execution instruction; and according to the multiple sequence control program steps in the preset sequence control program, execute the multiple preset sequence control instructions of the preset sequence control program in sequence, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount; wherein the sequence control component 32 is in an inoperable state.

[0209] It should be noted that the processing system 3 for power increase and decrease of the nuclear power plant includes an enabling control 31, a sequential control control 32 and a plurality of sequential execution controls 33#i. In this embodiment, the controls in the processing method for power increase and decrease of the nuclear power plant adopt the "Permit" + "Execute" combined operation mode and the split controls are arranged independently, that is, a KC control (i.e., the enabling control 31) is set to implement the "Permit" function; multiple KC controls (i.e., sequential execution controls 33#i) are set respectively to implement the "Execute" function of increasing or decreasing power; a KG control (i.e., sequential control control 32) with a sequential control function is set to control the sequential control program, and the sequential control control 32 is in an inoperable state. By activating the sequential control KG control by the KC control, the risk of misoperation by the operating operator can be effectively reduced, and the complexity of the operation is also reduced. When the working conditions require, the operator only needs to operate the enabling control and the sequential execution control, and the program will be executed automatically without human intervention.

[0210] Specifically, the enable control 31 is a permission control control for implementing the "Permit" function, that is, a control that allows or authorizes power increase or decrease operations; the sequence control execution control 33#i is an execution control for increasing or decreasing power. The sequence control execution controls can be set to multiple, which are used to indicate that the power is increased by a certain load adjustment amount or the power is reduced by a certain load adjustment amount. By splitting the controls, fine control of power increase and decrease can be achieved to avoid misoperation. In this embodiment, the number of sequence control execution controls 33#i is not specifically limited. The enable control 31 and the sequence control execution control 33#i can be a button, a switch or other input device, which is not specifically limited in this embodiment.

[0211] When the sequence control execution control 33#i is in a triggered state, the sequence control control 32 responds to the execution instruction of the sequence control execution control 33#i to start the preset sequence control program corresponding to the sequence control execution control 33#i; according to the execution instruction, the load adjustment amount is added to the multiple preset sequence control instructions of the preset sequence control program, so that the preset sequence control instruction carries the load adjustment amount corresponding to the execution instruction; and according to the multiple sequence control program steps in the preset sequence control program, the multiple preset sequence control instructions of the preset sequence control program are executed in sequence, so that the power of the nuclear power plant is increased or decreased according to the load adjustment amount.

[0212] In a possible implementation, the nuclear power plant power ramp processing system 3 of this embodiment includes: a termination control, wherein the termination control is used to generate a second termination instruction in response to an operator's trigger, so as to terminate the preset sequence control program according to the second termination instruction.

[0213] It should be noted that the termination control is a control used to manually trigger the termination of a preset sequence program. The termination control can be an emergency stop button, switch, or other form of input device. The second termination instruction is an emergency stop signal generated when the operator manually triggers the termination control to indicate the termination of the current preset sequence program. Unlike the first termination instruction, the second termination instruction is generated by the operator triggering the termination control. Upon receiving the second termination instruction of the termination control, the system will immediately terminate the preset sequence program associated with the sequence execution control and return the system to a safe state. That is, in an emergency, the operator can stop the current power increase or decrease operation by manually triggering the termination control, thereby avoiding potential risks or damages.
