[0002] In a nuclear reactor (such as a pressurized water reactor), the pressurizer is an important device used to maintain the pressure of the primary circuit system. At present, the pressurizer usually adopts a steam pressurizer or a nitrogen pressurizer. Among them, the steam pressurizer uses saturated water and water vapor as the medium, and the bottom is connected to the primary circuit heat pipe section through a surge tube, so as to achieve constant pressure control by adjusting the number of on-off electric heaters at the bottom of the steam pressurizer, the opening of the proportional electric heater, and the opening of the top spray valve. Nitrogen pressurizers are widely used in the design of integrated small reactors and some marine reactors because of their advantages such as simple pressure regulation and no need for heaters and spray pipelines. At present, there is a problem of poor pressure stabilization effect when controlling the pressure of the primary circuit system through a pressurizer. Summary of the invention

[0003] The main purpose of the embodiments of the present application is to propose a pressure control method, an electronic device, a voltage stabilization control system and a storage medium, aiming to improve the voltage stabilization effect of the voltage stabilization control system.

[0004] To achieve the above-mentioned purpose, a first aspect of an embodiment of the present application provides a pressure control method, which is applied to a pressure stabilization control system, wherein the pressure stabilization control system includes a pressurizer, the pressurizer is connected to a primary circuit of a nuclear reactor, and the pressurizer is used to control the pressure of the primary circuit. The method includes:

[0005] Obtaining a pressure measurement value and a pressure setting value of the pressure stabilizer;

[0006] Determining a pressure deviation value according to the pressure measurement value and the pressure set value;

[0007] If the absolute value of the pressure deviation value is less than or equal to a first preset value, adjusting the charging and discharging flow of the primary circuit according to the pressure deviation value and the pressure measurement value to control the pressure of the regulator;

[0008] If the absolute value of the pressure deviation is greater than the first preset value, the pressure regulator is controlled to inflate or exhaust air according to the pressure deviation to control the pressure of the pressure regulator.

[0009] To achieve the above-mentioned purpose, the second aspect of an embodiment of the present application proposes an electronic device, which includes a memory and a processor, the memory stores a computer program, and the processor implements the pressure control method described in the first aspect when executing the computer program.

[0010] To achieve the above purpose, a third aspect of an embodiment of the present application proposes a voltage stabilization control system, comprising:

[0011] a pressurizer, the pressurizer being connected to a primary circuit of a nuclear reactor, the pressurizer being used to control the pressure of the primary circuit; and

[0012] The electronic device described in the second aspect.

[0013] To achieve the above objectives, the fourth aspect of an embodiment of the present application proposes a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the pressure control method described in the first aspect is implemented.

[0014] The pressure control method, electronic device, voltage stabilization control system and storage medium proposed in the present application obtain the pressure measurement value and pressure setting value of the pressure stabilizer, and determine the pressure deviation value according to the pressure measurement value and the pressure setting value. If the absolute value of the pressure deviation value is less than or equal to the first preset value, the charging and discharging flow of a circuit is adjusted according to the pressure deviation value and the pressure measurement value to control the pressure of the pressure stabilizer. If the absolute value of the pressure deviation value is greater than the first preset value, the pressure stabilizer is controlled to inflate or exhaust according to the pressure deviation value to control the pressure of the pressure stabilizer. Through the above steps, the pressure deviation value between the pressure measurement value and the pressure setting value of the pressure stabilizer can be determined, and when the pressure deviation value is small, the pressure of the pressure stabilizer is controlled by adjusting the charging and discharging flow of a circuit to improve the accuracy of the control process. When the pressure deviation value is large, the pressure of the pressure stabilizer can be directly controlled by controlling the pressure stabilizer to inflate or exhaust, thereby improving the efficiency of the control process. In this way, the voltage stabilization effect of the voltage stabilization control system can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 1 is a flow chart of a pressure control method provided in an embodiment of the present application. The pressure control method is applied to a pressure stabilization control system, and can be specifically applied to an electronic device of the pressure stabilization control system. The pressure stabilization control system includes a pressure stabilizer, which is connected to a primary circuit of a nuclear reactor, and the pressure stabilizer is used to control the pressure of the primary circuit. The pressure control method may include but is not limited to steps 101 to 104.

[0028] Step 101, obtaining a pressure measurement value and a pressure setting value of the pressure stabilizer;

[0029] Step 102, determining a pressure deviation value according to the pressure measurement value and the pressure set value;

[0030] Step 103, if the absolute value of the pressure deviation value is less than or equal to the first preset value, adjusting the charging and discharging flow of the primary circuit according to the pressure deviation value and the pressure measurement value to control the pressure of the regulator;

[0031] Step 104: If the absolute value of the pressure deviation value is greater than the first preset value, the pressurizer is controlled to be inflated or exhausted according to the pressure deviation value to control the pressure of the pressurizer.

[0032] The primary circuit of a nuclear reactor is a coolant system for transferring the core heat energy of the nuclear reactor. The pressure stabilization control system includes a pressurizer, which is connected to the primary circuit. The pressure of the pressurizer is associated with the pressure of the primary circuit and can be used to control the pressure of the primary circuit. When the power of the nuclear reactor fluctuates, the temperature of the coolant in the primary circuit changes. Due to the phenomenon of thermal expansion and contraction, the volume of the coolant will change, thereby causing the pressure of the primary circuit to change, and the pressure of the pressurizer will also fluctuate accordingly. For example, when the power of the nuclear reactor increases, the coolant in the primary circuit expands due to the temperature increase, and the pressure of the primary circuit increases. At this time, part of the coolant flows into the pressurizer through the surge tube in the primary circuit, and the liquid level and pressure of the pressurizer increase. Then, by controlling the upper filling and lower discharge flow of the primary circuit, the pressure of the primary circuit can be reduced, and then the pressurizer discharges part of the coolant through the surge tube, and the pressure of the pressurizer is reduced. Alternatively, when the power of the nuclear reactor is reduced, the coolant in the primary circuit shrinks due to the temperature drop, and the pressure of the primary circuit drops. At this time, the pressurizer flows part of the coolant into the primary circuit through the surge tube, and the liquid level and pressure in the pressurizer drop. Then, by controlling the upper filling and lower discharge flow of the primary circuit, the pressure of the primary circuit can be increased. The primary circuit injects part of the coolant into the pressurizer through the surge tube, so that the liquid level and pressure in the pressurizer increase. Based on the above characteristics, the pressure of the pressurizer can be controlled to balance the pressure of the primary circuit with the pressure of the pressurizer, and maintain the stability of the pressure of the pressurizer and the pressure of the primary circuit.

[0033] Specifically, in order to reduce the possibility of damage to a circuit caused by overpressure or underpressure, in an embodiment of the present application, the pressure of the pressurizer can be controlled based on the pressure measurement value and the pressure setting value of the pressurizer, so that the pressure of the pressurizer is balanced with the pressure of the circuit. Among them, the pressure measurement value of the pressurizer can be collected by a pressure detection device arranged inside the pressurizer. The pressure setting value can be set according to the actual working conditions, and is not limited here. The pressure deviation value can be determined by subtracting the pressure measurement value from the pressure setting value. According to the pressure deviation value, the pressure control method to be adopted can be determined. Specifically, the electronic device can obtain a first preset value set in advance according to the actual situation. If the absolute value of the pressure deviation value is less than or equal to the first preset value, it is determined that the deviation between the pressure measurement value and the pressure setting value is small at this time. In order to improve the accuracy of the control process, the upper charging and lowering flow of the circuit can be adjusted according to the pressure deviation value and the pressure measurement value, thereby controlling the pressure of the pressurizer. The upper charging and lowering flow includes the flow injected into the circuit (i.e., the upper charging flow) and the flow flowing out of the circuit (i.e., the lowering flow). For example, the upstream flow rate injected into the primary circuit can be controlled according to the pressure deviation value, and the downstream flow rate flowing out of the primary circuit can be controlled according to the pressure measurement value to control the pressure of the pressurizer. If the absolute value of the pressure deviation value is greater than the first preset value, it is determined that the deviation between the pressure measurement value and the pressure setting value is large, and the inflation or exhaust of the pressurizer can be controlled according to the pressure deviation value, thereby controlling the pressure of the pressurizer to achieve the purpose of rapid pressure control and improve the efficiency of the control process. In this way, the pressure of the pressurizer and the pressure of the primary circuit can be controlled, and the pressure stabilization effect of the pressure stabilization control system is improved during the control process.

[0034] In addition, after obtaining the pressure measurement value, the pressure measurement value may be subjected to first-order filtering to obtain a processed pressure measurement value, so as to filter out noise in the pressure measurement value and improve the accuracy of subsequent control processes.

[0035] In the steps 101 to 104 shown in the embodiment of the present application, the pressure measurement value and the pressure setting value of the pressurizer are obtained, and the pressure deviation value is determined according to the pressure measurement value and the pressure setting value. If the absolute value of the pressure deviation value is less than or equal to the first preset value, the charging and discharging flow of a circuit is adjusted according to the pressure deviation value and the pressure measurement value to control the pressure of the pressurizer. If the absolute value of the pressure deviation value is greater than the first preset value, the pressurizer is controlled to inflate or exhaust according to the pressure deviation value to control the pressure of the pressurizer. Through the above steps, the pressure deviation value between the pressure measurement value and the pressure setting value of the pressurizer can be determined, and when the pressure deviation value is small, the pressure of the pressurizer is controlled by adjusting the charging and discharging flow of a circuit to improve the accuracy of the control process. When the pressure deviation value is large, the pressure of the pressurizer can be directly controlled by controlling the pressurizer to inflate or exhaust, thereby improving the efficiency of the control process. In this way, the pressure stabilization effect of the pressure stabilization control system can be improved.

[0036] In some embodiments, the voltage stabilization control system further includes an upper charging flow regulating valve and a lower discharging flow regulating valve, wherein the upper charging flow regulating valve and the lower discharging flow regulating valve are respectively connected to the primary circuit;

[0037] The charging and discharging flow rate includes a charging flow rate and a discharging flow rate. If the absolute value of the pressure deviation value is less than or equal to a first preset value, the charging and discharging flow rate of the primary circuit is adjusted according to the pressure deviation value and the pressure measurement value, including:

[0038] If the absolute value of the pressure deviation value is less than or equal to the first preset value, the opening of the charging flow regulating valve is controlled according to the pressure deviation value to adjust the charging flow of the first circuit;

[0039] The opening of the downstream flow regulating valve is controlled according to the pressure measurement value to adjust the downstream flow of the primary circuit.

[0040] Figure 2 This is a structural diagram of the voltage stabilization control system provided in the embodiment of the present application. Please refer to Figure 2 The voltage stabilization control system includes a voltage stabilizer 1, an upper charging flow regulating valve 3 and a lower discharge flow regulating valve 4, wherein the voltage stabilizer 1 is connected to a primary circuit 2 through a surge pipe, the upper charging flow regulating valve 3 is connected to the primary circuit 2 through an upper charging pipeline, and the lower discharge flow regulating valve 4 is connected to the primary circuit 2 through a lower discharge pipeline.

[0041] When the deviation between the pressure measurement value and the pressure setting value is small (i.e., the absolute value of the pressure deviation value is less than or equal to the first preset value), the electronic device can adjust the charging and discharging flow of a circuit according to the pressure deviation value and the pressure measurement value through the charging flow regulating valve and the discharging flow regulating valve, thereby controlling the pressure of the stabilizer. Among them, the charging and discharging flow includes the charging flow and the discharging flow, the charging flow refers to the flow injected into a circuit, and the discharging flow refers to the flow flowing out of a circuit. Specifically, when the absolute value of the pressure deviation value is less than or equal to the first preset value, the opening of the charging flow regulating valve target can be determined according to the pressure deviation value. For example, the pressure deviation value can be matched with a plurality of preset first deviation values ​​in a preset corresponding relationship to obtain the opening of the charging flow regulating valve target corresponding to the pressure deviation value. Among them, the preset corresponding relationship includes a plurality of preset first deviation values ​​and the opening corresponding to each preset first deviation value. For another example, a proportional integral differential control algorithm can be used to determine the opening of the charging flow regulating valve target according to the pressure deviation value. In this way, according to the target opening of the charging flow regulating valve, the opening of the charging flow regulating valve can be controlled to adjust the charging flow of a circuit.

[0042] According to the pressure measurement value, the target opening of the downstream flow regulating valve can be determined. For example, the pressure measurement value can be matched with a plurality of preset pressure values ​​in a preset correspondence relationship to obtain the target opening of the downstream flow regulating valve corresponding to the pressure measurement value. It should be noted that the preset correspondence relationship adopted in this process is different from the preset correspondence relationship in the aforementioned charging flow regulating valve opening control process. The preset correspondence relationship adopted in this process includes a plurality of preset pressure values ​​and the opening corresponding to each preset pressure value. In this way, according to the target opening of the downstream flow regulating valve, the opening of the downstream flow regulating valve can be controlled to adjust the downstream flow of a circuit. By controlling the charging and discharging flow of a circuit, the pressure of a circuit can be adjusted, thereby realizing the control of the pressure of the pressure stabilizer.

[0043] In some embodiments, controlling the opening of the charging flow regulating valve according to the pressure deviation value to adjust the charging flow of the primary circuit includes:

[0044] Determining a first target opening of the upper charging flow regulating valve according to the pressure deviation value;

[0045] Controlling the opening of the charging flow regulating valve according to the first target opening to adjust the charging flow of the primary circuit;

[0046] The step of controlling the opening of the downstream flow regulating valve according to the pressure measurement value to adjust the downstream flow of the primary circuit includes:

[0047] When the pressure measurement value is less than or equal to the second preset value, the first preset opening is used as the second target opening of the downstream flow regulating valve;

[0048] When the pressure measurement value is greater than the second preset value, the second preset opening is used as the second target opening of the downstream flow regulating valve, and the first preset opening is smaller than the second preset opening;

[0049] The opening of the downstream flow regulating valve is controlled according to the second target opening to adjust the downstream flow of the primary circuit.

[0050] The electronic device can control the opening of the charging flow regulating valve according to the pressure deviation value to adjust the charging flow of a circuit. Specifically, according to the pressure deviation value, the electronic device can determine the first target opening of the charging flow regulating valve. Exemplarily, the electronic device can match the pressure deviation value with multiple preset first deviation values ​​in a preset correspondence (including multiple preset first deviation values, and the opening corresponding to each preset first deviation value) to obtain the first target opening corresponding to the pressure deviation value. Alternatively, a proportional integral differential control algorithm can be used to determine the first target opening according to the pressure deviation value. After obtaining the first target opening, the opening of the charging flow regulating valve can be controlled according to the first target opening to adjust the charging flow of a circuit.

[0051] In addition, the electronic device can control the opening of the downstream flow regulating valve according to the pressure measurement value to adjust the downstream flow of a circuit. Specifically, when the pressure measurement value is less than or equal to the second preset value, the first preset opening can be used as the second target opening of the downstream flow regulating valve. When the pressure measurement value is greater than the second preset value, the second preset opening can be used as the second target opening of the downstream flow regulating valve. Among them, the first preset opening is less than the second preset opening. The first preset opening and the second preset opening are set according to actual control requirements. For example, 10% can be added to the first preset opening as the second preset opening. In this way, the second target opening can be determined, and the opening of the downstream flow regulating valve can be controlled according to the second target opening to adjust the downstream flow of a circuit. Through the above steps, the pressure of the regulator can be controlled by adjusting the charging flow and the downstream flow of a circuit.

[0052] In some embodiments, determining the first target opening of the charging flow regulating valve according to the pressure deviation value includes:

[0053] Obtaining the actual charging flow of the primary circuit;

[0054] A proportional-integral-differential control algorithm is used to calculate the target charging flow rate based on a preset first control parameter and the pressure deviation value, wherein the first control parameter includes a first proportional parameter, a first integral parameter, and a first differential parameter;

[0055] Determining a charging flow rate deviation value according to the actual charging flow rate and the target charging flow rate;

[0056] The proportional-integral-differential control algorithm is used to calculate based on a preset second control parameter and the charging flow deviation value to obtain the first target opening, where the second control parameter includes a second proportional parameter, a second integral parameter and a second differential parameter.

[0057] The electronic device can determine the first target opening of the charging flow regulating valve according to the pressure deviation value. Specifically, the electronic device can obtain the actual charging flow of a circuit, that is, the measured value of the charging flow of a circuit. And, through the proportional integral differential control algorithm, the target charging flow can be calculated based on the preset first control parameter and the pressure deviation value. Among them, the first control parameter includes a first proportional parameter, a first integral parameter and a first differential parameter, and the first proportional parameter, the first integral parameter and the first differential parameter are all obtained after being adjusted according to the actual situation. Subsequently, the actual charging flow and the target charging flow are subtracted to determine the charging flow deviation value. The second control parameter includes a second proportional parameter, a second integral parameter and a second differential parameter, and the second proportional parameter, the second integral parameter and the second differential parameter can also be obtained after being adjusted according to the actual situation. Based on the preset second control parameter and the charging flow deviation value, the electronic device can use the proportional integral differential control algorithm to calculate, so as to obtain the first target opening. Through the above steps, the accuracy of the first target opening can be improved, and the precise control of the opening of the charging flow regulating valve can be achieved.

[0058] In addition, after obtaining the actual charging flow, the actual charging flow may be subjected to first-order filtering to obtain the processed actual charging flow, and subsequent steps may be performed based on the processed actual charging flow to improve the accuracy of subsequent control processes.

[0059] In some embodiments, the pressure stabilization control system further comprises an air storage tank, a pressure relief box, an air charging valve and an air exhaust valve, the pressure stabilizer is connected to the air storage tank via the air charging valve, and the pressure stabilizer is connected to the pressure relief box via the air exhaust valve;

[0060] If the absolute value of the pressure deviation value is greater than the first preset value, controlling the pressurizer to inflate or exhaust air according to the pressure deviation value to control the pressure of the pressurizer includes:

[0061] If the absolute value of the pressure deviation value is greater than the first preset value, selecting one of the exhaust valve and the inflation valve as the target valve according to the pressure deviation value;

[0062] The opening of the target valve is controlled according to the pressure deviation value to achieve control of the pressure of the regulator.

[0063] Please continue reading Figure 2 . The pressure stabilization control system also includes an inflation valve 5, an exhaust valve 6, an air tank 7 and a pressure relief box 8. The pressure stabilizer 1 is connected to the air tank 7 through the inflation valve 5, and the pressure stabilizer 1 is connected to the pressure relief box 8 through the exhaust valve 6. In addition, the pressure stabilization control system also includes a safety valve 9, a high-pressure nitrogen cylinder group 10 and a pressure reducing valve 11. The gas flows out from the high-pressure nitrogen cylinder group 10 and enters the air tank 7 through the pressure reducing valve 11. Then, when the inflation valve 5 is opened, the gas flows out from the air tank 7 and enters the pressure stabilizer 1 through the inflation valve 5. When the exhaust valve 6 is opened, the gas flows out from the pressure stabilizer 1 and enters the pressure relief box 8 through the exhaust valve 6. Moreover, in the event of overpressure, the gas can be quickly discharged from the pressure stabilizer 1 to the pressure relief box 8 through the safety valve 9.

[0064] Based on the structure of the aforementioned voltage stabilization control system, when the absolute value of the pressure deviation value is greater than the first preset value, the electronic device can control the opening of the target valve according to the pressure deviation value to control the pressure regulator to inflate or exhaust, thereby realizing rapid pressure control of the pressure regulator. Among them, the target valve is an exhaust valve or an inflation valve. Specifically, when the absolute value of the pressure deviation value is greater than the first preset value, the electronic device can determine whether the pressure deviation value is a positive value or a negative value. If the pressure deviation value is a positive value, the exhaust valve is used as the target valve, and if the pressure deviation value is a negative value, the inflation valve is used as the target valve. In this way, the target valve can be determined, and then the opening of the target valve can be controlled according to the pressure deviation value to control the pressure regulator to inflate or exhaust, thereby realizing the control of the pressure of the pressure regulator.

[0065] In some embodiments, controlling the opening of the target valve according to the pressure deviation value includes:

[0066] determining a third target opening corresponding to the target valve according to the pressure deviation value;

[0067] If the target valve is the exhaust valve, the opening of the exhaust valve is controlled according to the third target opening to adjust the gas flow from the pressure stabilizer to the pressure relief tank;

[0068] If the target valve is the charging valve, the opening of the charging valve is controlled according to the third target opening to adjust the gas flow rate injected from the gas storage tank into the regulator.

[0069] The electronic device can control the opening of the target valve according to the pressure deviation value. Specifically, according to the pressure deviation value, the third target opening corresponding to the target valve can be determined. Exemplarily, the pressure deviation value can be matched with a plurality of preset second deviation values ​​in a preset corresponding relationship to obtain the third target opening corresponding to the pressure deviation value. Among them, the preset corresponding relationship adopted in the above process includes a plurality of preset second deviation values, and the opening corresponding to each preset second deviation value. Alternatively, a proportional integral differential control algorithm can also be used to determine the third target opening according to the pressure deviation value. The exhaust valve and the charging valve are not opened at the same time. If the target valve is an exhaust valve, after determining the third target opening, the opening of the exhaust valve can be adjusted to the third target opening, thereby adjusting the gas flow from the regulator to the pressure relief box. In addition, in the process of controlling the regulator to exhaust, in order to improve the exhaust efficiency of the regulator, the opening of the charging valve can also be adjusted to zero (i.e., the charging valve is controlled to be closed). If the target valve is a charging valve, after determining the third target opening, the opening of the charging valve can be adjusted to the third target opening to adjust the gas flow rate injected from the gas storage tank to the pressurizer. In addition, in the process of controlling the pressurizer to charge, in order to improve the charging efficiency of the pressurizer, the opening of the exhaust valve can also be adjusted to zero (i.e., the exhaust valve is controlled to be closed). In this way, the opening of the target valve can be controlled according to the pressure deviation value, thereby realizing rapid control of the pressure of the pressurizer.

[0070] In some embodiments, determining a third target opening corresponding to the target valve according to the pressure deviation value includes:

[0071] Matching the pressure deviation value with a plurality of preset deviation values ​​in a first corresponding relationship to obtain an opening corresponding to the pressure deviation value, and using the opening corresponding to the pressure deviation value as the third target opening, wherein the first corresponding relationship includes a plurality of the preset deviation values ​​and an opening of the target valve corresponding to each of the preset deviation values;

[0072] or,

[0073] A proportional-integral-differential control algorithm is used to calculate based on a preset third control parameter and the pressure deviation value to obtain a calculation result value, wherein the third control parameter includes a third proportional parameter, a third integral parameter and a third differential parameter;

[0074] The calculated result value is matched with multiple preset result values ​​in the second corresponding relationship to obtain the opening corresponding to the calculated result value, and the opening corresponding to the calculated result value is used as the third target opening. The second corresponding relationship includes multiple preset result values ​​and the opening of the target valve corresponding to each preset result value.

[0075] The electronic device can determine the third target opening corresponding to the target valve according to the pressure deviation value. Specifically, the electronic device can pre-construct the first correspondence or the second correspondence. Among them, the first correspondence includes multiple preset deviation values, and the opening of the target valve corresponding to each preset deviation value. The second correspondence includes multiple preset result values, and the opening of the target valve corresponding to each preset result value. It should be noted that the first correspondence and the second correspondence are both related to the target valve. When the target valve is an inflation valve, the first correspondence includes the opening of the inflation valve corresponding to each preset deviation value, and the second correspondence includes the opening of the inflation valve corresponding to each preset result value. When the target valve is an exhaust valve, the first correspondence includes the opening of the exhaust valve corresponding to each preset deviation value, and the second correspondence includes the opening of the exhaust valve corresponding to each preset result value.

[0076] In this way, when determining the third target opening based on the first corresponding relationship and the pressure deviation value, the electronic device can match the pressure deviation value with a plurality of preset deviation values ​​in the first corresponding relationship, thereby determining the preset deviation value matching the pressure deviation value. Further, the opening of the target valve corresponding to the preset deviation value matching the pressure deviation value can be determined as the opening corresponding to the pressure deviation value, and the opening corresponding to the pressure deviation value is used as the third target opening, so as to determine the third target opening corresponding to the target valve.

[0077] Alternatively, in order to improve the stability when controlling the opening of the target valve, the electronic device can also determine the third target opening based on the second corresponding relationship and the pressure deviation value. That is, a proportional-integral-differential control algorithm is used to calculate based on the preset third control parameter and the pressure deviation value to obtain a calculated result value. Among them, the third control parameter includes a third proportional parameter, a third integral parameter and a third differential parameter, and the third proportional parameter, the third integral parameter and the third differential parameter can all be obtained after being adjusted according to actual conditions. Subsequently, the calculated result value can be matched with multiple preset result values ​​in the second corresponding relationship, and the preset result value matching the calculated result value is determined, and the opening of the target valve corresponding to the preset result value matching the calculated result value is determined as the opening corresponding to the calculated result value, and then the opening corresponding to the calculated result value is determined as the third target opening.

[0078] By using any of the above two methods, the third target opening corresponding to the target valve can be determined according to the pressure deviation value, so that the opening of the target valve can be adjusted according to the third target opening, thereby achieving direct control of the pressure of the regulator.

[0079] Figure 3is a control logic diagram of the voltage stabilization control system provided by the embodiment of the present application. In a specific embodiment of the present application, the pressure control method can be divided into upper charging and lower discharge (i.e., adjusting the upper charging and lower discharge flow of a circuit through the upper charging flow regulating valve and the lower discharge flow regulating valve) and charging and exhausting (i.e., controlling the pressure of the regulator through the charging valve or the exhaust valve). The control logic is as follows: Figure 3 As shown. Subtract P', the pressure measurement value P of the regulator obtained after first-order filtering, from the pressure set value Psp to obtain the pressure deviation value ΔP of the regulator. After taking the absolute value of the pressure deviation value ΔP, |ΔP| is obtained, and the absolute value of the pressure deviation value |ΔP| is input into the low threshold comparator. P1 (i.e., the first preset value) is the switching threshold for upper charging and lower discharge control and charging and exhaust control. When the absolute value of the pressure deviation value |ΔP|≤P1, upper charging and lower discharge control is adopted. The target upper charging flow rate is output by the first proportional integral differential (PID) controller (i.e., a PID controller using a first proportional parameter, a first integral parameter, and a first differential parameter) according to the pressure deviation signal ΔP. Subsequently, the actual charging flow Q is obtained after first-order filtering, and the Q' obtained is subtracted from the target upper charging flow to obtain the upper charging flow deviation value ΔQ. The second PID controller (i.e., the PID controller using the second proportional parameter, the second integral parameter, and the second differential parameter) outputs the first target opening according to the upper charging flow deviation value ΔQ. Finally, the upper charging flow regulating valve is executed by the cabinet to control the opening of the upper charging flow regulating valve to adjust the actual charging flow of a circuit to the target upper charging flow. The downstream flow regulating valve is provided with two gears. When the downstream flow regulating valve is in any gear, the downstream flow is constant. P2 (i.e., the second preset value) is the switching threshold of the first gear (corresponding to the first preset opening) and the second gear (corresponding to the second preset opening) of the downstream flow regulating valve. The pressure measurement value P is filtered by the first order and the obtained P' is input into the high threshold comparator. When P'≤P2, the cabinet is controlled through the downstream flow regulating valve to make the opening of the downstream flow regulating valve constant at the first preset opening. At this time, the downstream flow is constant. When P'>P2, the cabinet is controlled through the downstream flow regulating valve to increase the opening of the downstream flow regulating valve by 10% on the basis of the first preset opening CMD1 (that is, adjusted to the second preset opening CMD2), and the downstream flow is also kept constant.

[0080] When the absolute value of the pressure deviation value |ΔP|>P1, the charging and exhaust control is adopted. At this time, the opening of the upper charging flow regulating valve is fixed to the measured opening value Vmes of the upper charging flow regulating valve when switching to the charging and exhaust control, and the opening of the lower discharge flow regulating valve is fixed to the measured opening value of the lower discharge flow regulating valve when switching to the charging and exhaust control, and the upper charging flow and the lower discharge flow are kept constant. The pressure deviation value ΔP is obtained by the third PID controller (i.e., the PID controller using the third proportional parameter, the third integral parameter and the third differential parameter), and then the corresponding opening V1 of the charging valve or the corresponding opening V2 of the exhaust valve is output through the GD1 function (i.e., the corresponding relationship between the calculated result value and the opening of the charging valve) or the GD2 function (i.e., the corresponding relationship between the calculated result value and the opening of the exhaust valve). The charging valve and the exhaust valve are not opened at the same time, that is, when the pressure deviation value is positive, the charging valve is closed and the exhaust valve is opened, and when the pressure deviation value is negative, the charging valve is opened and the exhaust valve is closed. Finally, the charging valve execution cabinet controls the charging valve to open according to the opening V1 corresponding to the charging valve, or the exhaust valve execution cabinet controls the exhaust valve to open according to the opening V2 corresponding to the exhaust valve, thereby adjusting the pressure of the stabilizer.

[0081] In addition, according to actual control requirements, the control logic of the above steps can also be used to adopt a control scheme in which both upper filling and lower discharge and filling and exhaust are put into use at the same time. However, the effects of the two actuators are prone to mutual influence, affecting the stability of control.

[0082] The pressure control method provided in the embodiment of the present application adopts a hierarchical control scheme of upper filling and lower discharge and filling and exhausting. Its control logic is relatively simple and requires fewer actuators. It can be applied to integrated small reactors and certain marine reactors, thereby quickly and accurately controlling the pressure of the stabilizer, reducing the pressure variation amplitude under transient and steady-state conditions, and improving the pressure stabilization effect of the pressure stabilization control system.
