Abstract
Description
Technical Field
[0001] The embodiments of the present application belong to the field of nuclear power technology, and in particular, relate to a method for executing a curve calibration experiment, an electronic device, and a computer program product. Background Art
[0002] The G9 curve is a curve that describes the relationship between the rod position of the power control rod in a nuclear power unit and the working load of the steam turbine. It has great guiding significance in the actual operation of nuclear power plants. However, in the actual operation of nuclear power plants, the relationship between the rod position of the power control rod and the working load of the steam turbine will change due to the actual situation. Therefore, operators need to calibrate the G9 curve regularly through curve calibration experiments.
[0003] When performing a curve calibration experiment, the operator can first adjust the initial power of one of the loop components in the nuclear power unit to the maximum power, and then control the movement of the power control rod according to the G9 curve to be adjusted, and record the actual workload of the steam turbine corresponding to different positions of the power control rod. Finally, the operator can process the recorded data to generate a new G9 curve.
[0004] However, when the actual insertion position of a power control rod deviates from the expected rod position corresponding to the power control rod, that is, when the power control rod has an overstep deviation, directly performing the curve calibration experiment based on the G9 curve to be adjusted and the maximum power value may cause the actual insertion position of the power control rod to exceed the rod position threshold, thereby causing the reactor to overheat and trigger a safety accident.

[0057] In the following description, specific details such as specific system structures, technologies, etc. are proposed for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the present application.
[0058] In nuclear power units with pressurized water reactors, the nuclear power units are mostly operated in "G" mode. In the base load state of "G" mode operation, the power control rod is a key tool for controlling the power increase and decrease of the reactor. Through the power control rod, the staff can quickly and efficiently adjust the power of the reactor, thereby improving the flexibility and stability of power regulation during the operation of the nuclear power unit, so that the power output of the nuclear power unit can meet the ever-changing power demand.
[0059] See also Figure 1 , shows a schematic diagram of the step sequence of a power control rod provided in an embodiment of the present application. Figure 1As shown, when the power control rod is located at the bottom of the reactor, the corresponding number of withdrawal steps can be 5; when the power control rod is located at the top of the reactor, the corresponding number of withdrawal steps of the power control rod can be 225. Since the action sequence of different power control rods is different, the number of withdrawal steps of each power control rod can be different at different rod positions. Among them, the number of withdrawal steps can represent the number of steps taken by the power control rod to be withdrawn from the initial position to the outside, and the number of withdrawal steps can be used to reflect the degree of movement of the power control rod outside the core. The N2 rod can be gradually withdrawn from the rod position of 0, the N1 rod can be gradually withdrawn from the rod position of 135, the G2 rod can be gradually withdrawn from the rod position of 270, and the G1 rod can be gradually withdrawn from the rod position of 405. When the rod position is 625, that is, all power control rods have been withdrawn, at this time, all power control rods are located at the top of the reactor.
[0060] When operating a nuclear power unit, the R&D personnel can first set the G9 curve corresponding to the nuclear power unit on the control device of the nuclear power unit. Then, the control device can automatically control the operation of the power control rod in the nuclear power unit according to the real-time power demand and the G9 curve, so that the power output of the nuclear power unit can effectively respond to the changes in the power demand of the power grid. The G9 curve is a curve used to represent the relationship between the rod position of the power control rod and the load of the steam turbine. Among them, the steam turbine load usually refers to the power load borne by the steam turbine in the nuclear power unit, that is, the amount of power that the steam turbine needs to generate. On the G9 curve, the rod position of each power control rod corresponds to a specific steam turbine load (or output electric power). For example, when the power demand of the power grid increases, the control device can automatically control the power control rod to move to the rod position corresponding to the current power demand according to the G9 curve, thereby increasing the power output of the nuclear power unit.
[0061] Among them, the power control rods in the nuclear power unit may include G1 rods, G2 rods, N1 rods and N2 rods. Specifically, G1 rods and G2 rods are mainly used for fine adjustment of the reactor power. During the stable operation stage of the nuclear power unit, when the staff needs to make small and precise adjustments to the reactor power, they can make adjustments through G1 rods and G2 rods. N1 rods and N2 rods are mainly used to compensate for changes in reactor reactivity. During the operation of the reactor, the reactivity may change due to various factors, such as fuel consumption, coolant temperature changes, etc. At this time, in order to maintain the stable operation of the reactor, the staff can compensate for the changes in the reactor reactivity through N1 rods and N2 rods. During the reactor power adjustment process, different power adjustment rods can act in a certain order and overlapping relationship to achieve precise and stable power control.
[0062] However, in the actual operation of nuclear power units, factors such as reactor refueling and changes in reactor burnup will cause changes in the power distribution of the reactor, that is, the reactor power caused by the power control rod in the same position may change, which in turn causes changes in the power generated by the nuclear power unit in the same position of the power control rod. Therefore, in order to improve the accuracy of the G9 curve, the staff of the nuclear power unit needs to perform curve calibration experiments on the G9 curve regularly. However, during a curve calibration experiment, the staff found that the actual rod position of a power control rod and the expected rod position corresponding to the power control rod had a deviation of 2 steps, that is, a power control rod had a step-by-step deviation event. After a detailed investigation and study of the deviation of the control rod, the staff confirmed that the step-by-step deviation event was caused by defects in the logical configuration of the power control rod, and the staff could not correct the configuration logic by themselves in a short time, and needed to work with the manufacturer of the power control rod to upgrade the logical configuration to solve it.
[0063] Furthermore, if the curve calibration experiment cannot be performed, the accuracy of the G9 curve will be low. Controlling the operation of nuclear power units through the G9 curve with low accuracy can easily lead to a mismatch between the power generated by the nuclear power units and the power demand of the power grid. For example, when the power needs to be increased, the position of the power control rod is inaccurate according to the inaccurate G9 curve. If the position of the power control rod moves too much, the reactor power will rise too quickly, exceeding the target power, and may cause the nuclear power unit to operate at overpower; if the position of the power control rod moves too little, the expected power increase effect cannot be achieved, resulting in slow power growth and failure to meet the power demand of the power grid.
[0064] In view of this, researchers need to propose a method for performing a curve calibration experiment under the step deviation state of the power control rod. The technical solution of the present application is described below through specific embodiments.
[0065] Reference Figure 2 , which shows a schematic diagram of a method for executing a curve calibration experiment provided in an embodiment of the present application, which may specifically include the following steps:
[0066] S201. If an overlap deviation event is identified at any time during the curve calibration experiment, a maximum deviation step number corresponding to the power control rod is determined based on the deviation step number of the power control rod in at least one expected rod position.
[0067] In this embodiment, during the process of performing the curve calibration experiment, the electronic device can continuously detect whether each power control rod in the nuclear power unit has a step deviation event. If the electronic device does not detect a step deviation event during the process of performing the curve calibration experiment, the electronic device can continue to perform the curve calibration experiment. If the electronic device identifies that a step deviation event occurs in any power control rod in the nuclear power unit at any time during the execution of the curve calibration experiment, the electronic device can execute the method in S201 to S204 of the embodiment of the present application to safely perform the curve calibration experiment in a step deviation state. Exemplarily, the electronic device can identify the step deviation event in the preparation stage of the curve calibration experiment, or it can identify the step deviation event during the execution of the curve calibration experiment. When the electronic device identifies the step deviation event during the execution of the curve calibration experiment, in order to prevent the nuclear power unit from having a safety event, the electronic device can initiate a stop command to the nuclear power unit to control the nuclear power unit to stop performing the curve calibration experiment. The electronic device can also generate a first alarm message, and display the first alarm message through a display device to inform the staff that a step deviation event has occurred in a power control rod in the nuclear power unit. After the electronic device identifies the step-by-step deviation event, in order to improve the operating safety of the nuclear power unit in the step-by-step deviation state of the power control rod, the method in S201 to S204 of the embodiments of the present application can be executed to safely perform the curve calibration experiment in the step-by-step deviation state.
[0068] Specifically, the electronic device may first obtain the deviation step numbers corresponding to the power control rods in each expected rod position where the step-by-step deviation event occurs. Then, the electronic device may determine the maximum deviation step number corresponding to the power control rod based on the deviation step numbers of the power control rods in all expected rod positions. Among them, when there is only one power control rod in the nuclear power unit that has a step-by-step deviation event, the electronic device may determine the maximum value of all the deviation step numbers corresponding to the power control rod as the maximum deviation step number. When there are two or more power control rods in the nuclear power unit that have a step-by-step deviation event, the electronic device may obtain the deviation step numbers corresponding to all the power control rods in each expected rod position, and determine the maximum value of all the deviation step numbers obtained as the maximum deviation step number.
[0069] The expected rod position may be the rod position value in the insertion instruction sent by the electronic device to the driving mechanism of the power control rod when controlling the operation of the power control rod, that is, the rod position value required for the power control rod to be inserted when the electronic device controls the operation of the power control rod. The deviation step number may be the difference between the actual rod position driven by the driving mechanism of the power control rod to insert the power control rod after receiving the insertion instruction and the expected rod position in the insertion instruction. The actual rod position may be the rod position value actually driven by the driving mechanism of the power control rod to insert the power control rod after receiving the insertion instruction.
[0070] In a possible implementation, during the curve calibration experiment, the electronic device can continuously detect the actual rod position of each power control rod in the nuclear power unit through the step counter. For any power control rod in the nuclear power unit, if the electronic device determines that the actual rod position fed back by the step counter is not equal to the expected rod position that the power control rod should currently reach, the electronic device can determine that a step deviation event has occurred in the power control rod. For any power control rod in the nuclear power unit, if the electronic device determines that the actual rod position fed back by the step counter is equal to the expected rod position that the power control rod should currently reach, the electronic device can determine that no step deviation event has occurred in the power control rod.
[0071] S202: Determine a correction factor corresponding to the relationship curve according to the maximum deviation step number.
[0072] In this embodiment, after determining the maximum deviation step number, the electronic device can determine the correction factor corresponding to the relationship curve according to the maximum deviation step number. After determining the maximum deviation step number, the electronic device can calculate the correction factor corresponding to the relationship curve by two different methods.
[0073] Method 1: Calculate the correction factor by the reactivity difference corresponding to the maximum deviation step number.
[0074] In a possible implementation, after determining the maximum deviation step number, the electronic device can move the power control rod to the rod position corresponding to the maximum deviation step number, and the desired rod position corresponding to the power control rod and the actual rod position of the power control rod are respectively input into a preset reactivity algorithm, so as to calculate the first reactivity corresponding to the desired rod position and the second reactivity corresponding to the actual rod position respectively through the reactivity algorithm. Then, the electronic device can use the difference between the first reactivity and the second reactivity as the reactivity difference between the desired rod position and the actual rod position. Among them, the reactivity algorithm in the electronic device can be any algorithm that can calculate the reactivity of the reactor, such as a point reactor kinetic equation algorithm, a reactivity coefficient algorithm, a Monte Carlo algorithm, etc.
[0075] After determining the reactivity difference, the electronic device can input the reactivity difference and the power coefficient corresponding to the nuclear power unit into a preset correction factor function to determine the correction factor corresponding to the relationship curve through the correction factor function. Among them, the power coefficient is a coefficient that represents the rate at which the reactivity of the reactor changes with the thermal power of the reactor, that is, it represents the value of the change in reactivity when the thermal power of the reactor changes by one percent. The unit of the power coefficient can be one percent power per centimum (abbreviated as pcm / % power). The power coefficient can be calculated by the electronic device based on the reactor physical model (such as the neutron transport model) preset by the R&D personnel, analyzing and calculating the fuel, coolant, boron concentration, burnup value and other information of the reactor core. The correction factor function can be specifically as shown below.
[0076]
[0077] Wherein, ΔP may be a correction factor and Δp may be a reactivity difference. It can be the power factor of the nuclear power unit.
[0078] In this embodiment, since the electronic device can calculate the correction factor according to the reactivity difference, that is, the calculation of the power correction factor takes into account the influence of the step deviation on the reactivity of the reactor, the method provided in this embodiment can improve the accuracy of the calculated correction factor.
[0079] Method 2: Calculate the correction factor through the relationship curve.
[0080] In a possible implementation, after determining the maximum deviation step number, the electronic device may calculate the maximum deviation rod position corresponding to each desired rod position of the power control rod according to the maximum deviation step number. The maximum deviation rod position may be the sum of the desired rod position and the maximum deviation step number. Exemplarily, when the maximum deviation step number is 4, for the desired rod position with a step value of 200 in the G9 curve, the corresponding maximum deviation rod position may be 204. Then, the electronic device may determine the power difference between each desired rod position and the maximum deviation rod position corresponding to the desired rod position according to the G9 curve. Specifically, for any desired rod position, the electronic device may query the G9 curve according to the desired rod position to determine the first workload value of the steam turbine corresponding to the rod position value of the desired rod position in the G9 curve. The electronic device may also query the G9 curve according to the maximum deviation rod position corresponding to the desired rod position to determine the second workload value of the steam turbine corresponding to the rod position value of the maximum deviation rod position in the G9 curve. Then, the electronic device may use the difference between the first workload value and the second workload value as the power difference. The electronic device can calculate the power difference values corresponding to all the expected rod positions of the power control rod respectively, and use the maximum value of all the calculated power difference values as the correction factor.
[0081] In this embodiment, after determining the maximum deviation step number, the electronic device can directly determine the correction factor based on the maximum deviation step number and the relationship curve without combining the reactor model and other data for calculation. Therefore, the method provided in this embodiment has a small amount of calculation and higher usability.
[0082] S203. If the correction factor meets the power adjustment condition, the correction factor is input into a preset power adjustment function to determine the initial power corresponding to the nuclear power unit where the power control rod is located.
[0083] In this embodiment, during the actual curve calibration experiment of the nuclear power unit, the addition of the correction factor will cause the action change of the power control rod to lag behind the change of the electric power output by the nuclear power unit, which may lead to the problem of overheating of the nuclear power unit during the test. When the nuclear power unit is overheated, the bypass exhaust system in the nuclear power unit will be opened to discharge the excess steam generated in the steam generator through the bypass exhaust system, so as to avoid the temperature and pressure in the steam generator exceeding the protection threshold and ensure the safety of the nuclear power unit. Since a large amount of steam will be discharged after the bypass exhaust system is opened, this may cause the temperature field around the nuclear power unit to change. However, in the curve calibration experiment, temperature is a key parameter for evaluating the thermal performance and reactivity of the nuclear power unit. The high temperature of the steam discharged by the bypass exhaust system will increase the ambient temperature, thereby affecting the accuracy of the temperature measurement probe in the test, causing the measured temperature value to deviate from the true value, and affecting the judgment of the test results. Therefore, after the correction factor is introduced, in order to reduce the probability of overheating of the nuclear power unit and thus causing the bypass exhaust system to be opened, the electronic device can adjust the initial power of any loop component in the nuclear power unit according to the correction factor before conducting the experiment.
[0084] Specifically, the electronic device can determine whether the correction factor meets the power adjustment condition preset by the R&D personnel. If the electronic device determines that the correction factor meets the power adjustment condition, the electronic device can input the correction factor into the power adjustment function preset by the R&D personnel to calculate the initial power corresponding to the nuclear power unit where the power control rod is located through the power adjustment function.
[0085] In a possible implementation, if the electronic device determines that the correction factor does not meet the power adjustment condition, the maximum power value pre-set by the R&D personnel can be used as the initial power of the nuclear power unit.
[0086] Among them, the nuclear power unit may include a primary circuit component and a secondary circuit component. The primary circuit component is mainly composed of equipment such as a reactor pressure vessel, a steam generator, a main pump, a pressurizer, and connecting pipes, which are used to take the heat energy released by the reactor during the nuclear fission reaction out of the reactor and transfer the heat energy to the secondary circuit component. The secondary circuit component is mainly composed of equipment such as a steam turbine generator set, a steam generator, a generator, and a cooling system. The secondary circuit component can convert the heat energy transferred from the primary circuit component into steam through a heat exchanger, and drive the steam turbine to generate mechanical energy through steam, and then drive the generator to generate electricity through mechanical energy. The initial power determined by the electronic equipment can be the power of the secondary circuit component in the nuclear power unit when the curve calibration experiment starts.
[0087] S204: Perform a curve calibration experiment based on the initial power, the correction factor and the relationship curve.
[0088] In this embodiment, after determining the initial power and the correction factor, the electronic device can control the nuclear power unit to perform a curve calibration experiment according to the initial power, the correction factor and the relationship curve. Specifically, the electronic device can first adjust the power of the secondary circuit component in the nuclear power unit to the initial power.
[0089] Through the method provided in this embodiment, in the event of a step-by-step deviation event, the electronic device can determine the correction factor based on the maximum number of deviation steps, and adjust the driving strategy of the control rod drive mechanism for the power control rod in combination with the power correction in the curve correction experiment. Therefore, the method provided in this embodiment can reduce the probability that the actual insertion position of the power control rod exceeds the rod position threshold, thereby improving the accuracy of performing the curve calibration experiment under the step-by-step deviation state.
[0090] In addition, since the electronic device can determine whether the current situation meets the power adjustment conditions based on the correction factor corresponding to the maximum number of deviation steps, and adjust the initial power of the nuclear power unit when performing the curve calibration experiment through the correction factor and the power adjustment function when the power adjustment conditions are met, the method provided in this embodiment can reduce the probability of overheating of the nuclear power unit due to excessive initial power when performing the curve calibration experiment based on the correction factor, and further improve the safety of performing the curve calibration experiment in the case of overlapping step deviation.
[0091] In a possible implementation, after the electronic device determines the initial power corresponding to the correction factor through the power adjustment function, it can determine whether the initial power is greater than or equal to the power threshold preset by the R&D personnel. If the electronic device determines that the initial power is greater than or equal to the power threshold, the electronic device can determine that the adjusted initial power can meet the most basic power requirements of the curve calibration experiment. At this time, the electronic device can perform the curve calibration experiment based on the adjusted initial power, the correction factor and the relationship curve. If the electronic device determines that the initial power is less than the power threshold, the electronic device can determine that the adjusted initial power cannot meet the most basic power requirements of the curve calibration experiment, that is, the curve calibration experiment performed at the initial power has no practical significance. At this time, the electronic device can generate a first warning message and display the first warning message through a display device to prompt the user that the curve calibration experiment cannot be performed.
[0092] Through the method provided in this embodiment, after determining the initial power, the electronic device can judge whether the initial power meets the basic requirements of the curve calibration experiment according to the power threshold, and perform the curve calibration experiment only when the initial power is greater than or equal to the power threshold. Therefore, the method provided in this embodiment can improve the availability of the curve calibration experiment performed under the step deviation state.
[0093] Specifically, before the curve calibration experiment is performed, the electronic device can first adjust the power of the secondary circuit component in the nuclear power unit to the initial power. Then, the electronic device can turn on the nuclear power unit to conduct the curve calibration experiment. After the curve calibration experiment begins, the electronic device can gradually change the output power that the secondary circuit component in the nuclear power unit needs to achieve at a specific rate, and initiate a power control signal containing the output power to the control rod drive mechanism to drive the power control rod to operate. In this process, the electronic device can continuously record key parameters such as reactor power, coolant temperature, pressure, and the actual rod position of the power control rod, so that researchers can determine a new G9 curve based on all the recorded data after the experiment. For example, the electronic device can reduce the output power of the secondary circuit component at a certain megawatt per minute, gradually reducing it from a higher power level to a predetermined low power value, such as from 984MW to 880MW, and continuously record key parameters such as reactor power, coolant temperature, pressure, and the actual rod position of the power control rod.

During the curve calibration experiment, the control device can input a power control signal to the secondary circuit power selection module in the control rod drive mechanism, and the power control module can determine the output electric power that the secondary circuit component of the current nuclear power unit needs to reach based on the received signal, and input the output electric power to the power calculation module. Then, the power calculation module can determine the power setting value based on the correction factor and output electric power pre-set by the R&D personnel, and input the power setting value to the function generator module. The function generator module can determine the expected rod position corresponding to the current output electric power based on the power setting value, and input the expected rod position to the second function generator. Then, the second function generator can generate a drive signal based on the expected rod position and the current actual rod position of the power control rod fed back by the step counter. The second function generator can transmit the drive signal to the drive device to adjust the power control rod through the drive device.

After determining the temperature change value corresponding to the correction factor, the electronic device can determine the expected maximum temperature corresponding to the correction factor according to the temperature change value and the historical maximum temperature of the nuclear power unit. Specifically, the electronic device can determine the sum of the temperature change value and the historical maximum temperature as the expected maximum temperature. Among them, the historical maximum temperature can be the maximum value of the overheating temperature of the reactor in all historical data of the nuclear power unit performing the curve calibration experiment.

[0103] In this embodiment, after determining the expected maximum temperature corresponding to the correction factor, the electronic device can determine whether the correction factor meets the power adjustment condition by judging whether the expected maximum temperature is greater than the temperature threshold value preset by the R&D personnel. The temperature threshold value may be the limit value of the overheat temperature of the reactor when the nuclear power unit performs a curve calibration experiment. If the electronic device determines that the expected maximum temperature corresponding to the correction factor is greater than the temperature threshold value, that is, the correction factor meets the power adjustment condition, the electronic device can input the correction factor into the power adjustment function preset by the R&D personnel to calculate the initial power corresponding to the correction factor through the power adjustment function.

After determining the expected maximum temperature corresponding to the correction factor, the electronic device can determine the temperature difference according to the expected maximum temperature and the temperature threshold of the nuclear power unit. Specifically, the electronic device can use the difference between the expected maximum temperature and the temperature threshold as the temperature difference. Then, the electronic device can determine the initial power corresponding to the correction factor according to the temperature difference, the rated power generation of the nuclear power unit, and the actual power generation of the nuclear power unit.

P can be the actual power generation of the nuclear power unit. 额 It can be the rated power of the nuclear power unit. est It can be the expected maximum temperature corresponding to the correction factor. limit It can be the temperature threshold of the nuclear power unit.
[0108] S2033: If the expected maximum temperature is less than or equal to the preset temperature threshold, the preset maximum power value is used as the initial power.
[0109] In this embodiment, if the electronic device determines that the expected maximum temperature corresponding to the correction factor is less than or equal to the temperature threshold, that is, the correction factor does not meet the power adjustment condition, the electronic device can use the preset maximum power value as the initial power. Exemplarily, the electronic device can determine the full power value of the secondary circuit component in the nuclear power unit as the initial power of the secondary circuit component.
[0110] In this embodiment, the electronic device can calculate the expected maximum temperature that may occur in the nuclear power unit after the correction factor is introduced based on the correction factor, and judge whether the correction factor meets the power adjustment condition based on the expected maximum temperature. Furthermore, since the main purpose of the electronic device to adjust the initial power is to reduce the probability of overheating of the nuclear power unit, the method provided in this embodiment can improve the accuracy of the electronic device's judgment on whether the initial power needs to be adjusted, thereby improving the accuracy of the initial power.
