[0063] Embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation of the present disclosure.

[0064] A method, apparatus, computer device, and storage medium for determining the reactor power of a high-temperature gas-cooled reactor nuclear power plant according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings.

[0065] In the embodiments of the present disclosure, the method for determining the reactor power of the high-temperature gas-cooled reactor nuclear power plant is configured in a device for determining the reactor power of the high-temperature gas-cooled reactor nuclear power plant as an example. The device for determining the reactor power of the high-temperature gas-cooled reactor nuclear power plant can be applied to any computer device, so that the computer device can execute the function of determining the reactor power of the high-temperature gas-cooled reactor nuclear power plant.

[0066] Among them, the computer device can be a personal computer (PC for short), a cloud device, a mobile device, etc. The mobile device can be, for example, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, a vehicle-mounted device, etc., which are hardware devices with various operating systems, touchscreens, and / or displays.

[0067] Figure 1 It is a schematic flow chart of the method for determining the reactor power of the high-temperature gas-cooled reactor nuclear power plant provided by the embodiments of the present disclosure.

[0068] As Figure 1 shown, the method for determining the reactor power of the high-temperature gas-cooled reactor nuclear power plant may include the following steps:

[0069] Step 101: Determine the current plant load deviation of the high-temperature gas-cooled reactor nuclear power plant, the current first thermal power value, the first set power value of the first nuclear steam supply system (NSSS) module in the high-temperature gas-cooled reactor nuclear power plant, as well as the current second thermal power value and the second set power value of the second NSSS module.

[0070] Among them, the nuclear steam supply system (NSSS) is a system in the high-temperature gas-cooled reactor nuclear power plant that uses nuclear energy to generate steam, and its function is equivalent to the boiler steam system in a thermal power plant. Generally, one NSSS can be set in the high-temperature gas-cooled reactor nuclear power plant, or multiple NSSSs can also be set, such as two, six, etc. The present disclosure does not limit this.

[0071] In addition, the first thermal power value can be understood as the current thermal power value of the first NSSS module; the first set power value can be understood as the current set power value of the first NSSS module, such as a set expected value, etc. The present disclosure does not limit this.

[0072] In addition, the second thermal power value can be understood as the current thermal power value of the second NSSS module; the second set power value can be understood as the current set power value of the second NSSS module, such as a set expected value, etc. The present disclosure does not limit this.

[0073] Optionally, the current grid load demand value can be obtained, and then the power station load deviation can be determined according to the relationship between the grid load demand value and the first set power value and the second set power value.

[0074] Among them, the grid load demand value can be input by the user through the terminal device, or can also be a value determined by analyzing the current grid-side demand, etc. The present disclosure does not limit this.

[0075] For example, if the grid load demand is Pe0, the first set power value is Pt10, and the second set power value is Pt20, then the power station load deviation can be expressed as: ΔPt = 2Pe0 - (Pt10 + Pt20).

[0076] Step 102, in response to the first thermal power value, the first set power value, the second thermal power value, and the second set power value satisfying a preset condition, determine the target NSSS module according to the power station load deviation, the first set power value, and the second set power value.

[0077] Among them, the preset condition can be understood as a condition set in advance. Usually, when the first thermal power value, the second set power value, the second thermal power value, and the second set power value all satisfy the preset condition, it can be considered that the current first NSSS and second NSSS are both in the steady-state process. At this time, the dual-reactor power distribution can be carried out without affecting the operation of the high-temperature gas-cooled reactor nuclear power plant.

[0078] Optionally, it can be determined that the preset condition is satisfied when both the first deviation between the first thermal power value and the first set power value and the second deviation between the second thermal power value and the second set power value are between the first threshold and the second threshold.

[0079] Among them, the first threshold and the second threshold can be preset values. For example, the first threshold can be 5% RFP, and the second threshold can be -5% RFP; or the first threshold is -3% RFP, and the second threshold can be 3% RFP, etc. The present disclosure does not limit this.

[0080] In addition, the first deviation may be the difference between the first thermal power value and the first set power value, the second deviation may be the difference between the second thermal power value and the second set power value, and so on. The present disclosure does not limit this.

[0081] It can be understood that the thermal power value may be greater than the set power value, or the thermal power value may also be smaller than the set power value, etc. Thus, the first deviation and the second deviation may be positive values, or may also be negative values, etc. The present disclosure does not limit this.

[0082] For example, when the first threshold is +6% RFP and the second threshold is -6% RFP, if the first deviation is 4% RFP and the second deviation is -1% RFP, and both are between the first threshold and the second threshold, then it can be determined that the preset condition is currently met, and reactor power distribution can be performed, etc. The present disclosure does not limit this.

[0083] Optionally, when the power plant load deviation is positive, the NSSS module corresponding to the larger power value among the first set power value and the second set power value can be determined as the target NSSS module; or, when the power plant load deviation is negative, the NSSS module corresponding to the smaller power value among the first set power value and the second set power value can be determined as the target NSSS module.

[0084] It can be understood that if the power plant load deviation is positive, it can be considered that the current thermal power value of the nuclear power plant cannot meet the grid load demand. At this time, a load increase operation can be performed on the reactor. For example, if the first set power value of the first NSSS module is greater than the second set power value of the second NSSS, then the first NSSS module can be determined as the target NSSS module at this time.

[0085] Or, when the power plant load deviation is negative, it can be considered that the input grid load demand is less than the current thermal power value of the nuclear power plant. At this time, a load reduction operation can be performed on the reactor. For example, if the first set power value of the first NSSS module is greater than the second set power value of the second NSSS, then the second NSSS module can be determined as the target NSSS module at this time.

[0086] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the method for determining the target NSSS module in the embodiments of the present disclosure, etc.

[0087] Step 103: Determine the first target power value of the target NSSS module and the second target power value of another NSSS module other than the target NSSS module according to the relationship between the power plant load deviation and the target power value corresponding to the target NSSS module.

[0088] For example, when the power plant load deviation is positive and the target NSSS module is the first NSSS module, if the power plant load deviation ΔPt is 30% RFP, the target NSSS module is 70% RFP, and the second NSSS module is 30% RFP, then the first target power value of the target NSSS module can be determined as: 70% FRP + 30% RFP, and the second NSSS module is 30% RFP.

[0089] Alternatively, when the power plant load deviation is negative and the target NSSS module is the first NSSS module, if the power plant load deviation ΔPt is -5% RFP, the target NSSS module is 60% RFP, and the second NSSS module is 70% RFP, then the first target power value of the target NSSS module can be determined as: 60% FRP - 5% RFP, and the second NSSS module is 70% RFP.

[0090] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the determination of the first target power value, the second target power value, etc. in the embodiments of the present disclosure.

[0091] Therefore, in the embodiments of the present disclosure, the target NSSS module can be determined based on the power plant load deviation, the power value of the first NSSS module, and the power value of the second NSSS module, and the target power values of the target NSSS module and another NSSS module can be determined. This process can be automatically realized without manual operation, thereby not only reducing the labor cost but also improving the efficiency of reactor power configuration.

[0092] In the embodiments of the present disclosure, the current power plant load deviation of the high-temperature gas-cooled reactor nuclear power plant, the current first thermal power value and the first set power value of the first nuclear steam supply system (NSSS) module in the high-temperature gas-cooled reactor nuclear power plant, and the current second thermal power value and the second set power value of the second NSSS module can be determined first. Then, in response to the first thermal power value, the first set power value, the second thermal power value, and the second set power value satisfying the preset conditions, the target NSSS module is determined according to the power plant load deviation, the first set power value, and the second set power value. Then, according to the relationship between the power plant load deviation and the target power value corresponding to the target NSSS module, the first target power value of the target NSSS module and the second target power value of another NSSS module other than the target NSSS module are determined. Thus, the power plant load deviation, the first thermal power value, the first set power value, the second thermal power value, and the second set power value corresponding to the first NSSS and the second NSSS can be determined first, and then when the preset conditions are met, the target power values of the two NSSS modules can be automatically determined according to the power plant load deviation and the respective power values of the NSSS modules. This process can be realized without manual operation, thereby not only reducing the labor cost but also improving the efficiency of reactor power configuration.

[0093] Figure 2 This is a schematic flowchart of a method for determining the reactor power of a high-temperature gas-cooled reactor nuclear power plant provided by an embodiment of the present disclosure.

[0094] As Figure 2 shown, the method for determining the reactor power of the high-temperature gas-cooled reactor nuclear power plant may include the following steps:

[0095] Step 201: Determine the current plant load deviation of the high-temperature gas-cooled reactor nuclear power plant, the current first thermal power value of the first nuclear steam supply system (NSSS) module in the high-temperature gas-cooled reactor nuclear power plant, the first set power value, and the current second thermal power value and the second set power value of the second NSSS module.

[0096] Step 202: In response to the first thermal power value, the first set power value, the second thermal power value, and the second set power value satisfying a preset condition, determine a target NSSS module according to the plant load deviation, the first set power value, and the second set power value.

[0097] Optionally, when the plant load deviation is positive, the NSSS module corresponding to the larger power value among the first set power value and the second set power value may be determined as the target NSSS module; when the plant load deviation is negative, the NSSS module corresponding to the smaller power value among the first set power value and the second set power value may be determined as the target NSSS module.

[0098] Step 203: When the plant load deviation is positive, determine a first difference between a first value and the set power value corresponding to the target NSSS module.

[0099] Wherein, the first value may be a pre-set value, such as 100% RFP, 98% RFP, etc. For example, if the limit of the set power value of any NSSS module is: 50% RFP - 100% RFP, then the second value may be determined as 50% RFP; or, if the limit of the set power value of any NSSS module is: 60% RFP - 100% RFP, then the second value may be determined as 60% RFP, etc. The present disclosure does not limit this.

[0100] For example, when the first value is 100% RFP, if the target NSSS module is the second module and its corresponding set power value is 80% RFP, the first difference between the two is 20% RFP. The present disclosure does not limit this.

[0101] Step 204: When the plant load deviation is greater than the first difference, determine the first value as the first target power value of the target NSSS module.

[0102] For example, when the first value is 100% RFP, if the target NSSS module is the second module and the power plant load deviation is 40% RFP and the first difference is 20% RFP, then 100% RFP can be determined as the first target power value of the target NSSS module, that is, the first target power value of the second NSSS module is 100% RFP, and so on. The present disclosure does not limit this.

[0103] Step 205: Based on the first set power value, the second set power value, the first value, and the first difference, determine the second target power value of another NSSS module other than the target NSSS module.

[0104] For example, when the power plant load deviation is positive, such as the power plant load deviation is 20% RFP. If the first value is 100% RFP, the first set power value of the first NSSS module 90% RFP is greater than the second set power value of the second NSSS module 65% RFP, then it can be determined that the first NSSS module is the target NSSS module. After that, the first difference can be determined as: 100% RFP - 90% RFP = 10% RFP. Since the power plant load deviation 20% RFP is greater than the first difference 10% RFP, then at this time, the first target power value of the target NSSS module can be determined as: 100% RFP, that is, it is determined that the first target power value of the first NSSS module is: 100% RFP. After that, another NSSS module, that is, the second target power value of the second NSSS module can be determined as: 65% RFP + 20% RFP - 100% RFP + 90% RFP = 75% RFP.

[0105] It should be noted that the above examples are only illustrative and cannot be used as limitations on the power plant load deviation, the first value, the first set power value, the second set power value, etc. in the embodiments of the present disclosure.

[0106] Step 206: When the power plant load deviation is less than or equal to the first difference, based on the first value, the first set power value, and / or the second set power value, determine the first target power value of the target NSSS module.

[0107] It can be understood that when the power plant load deviation is less than or equal to the first difference, only by performing a load increase operation on the first target power value of the target NSSS module can the power plant load demand be met, without adjusting the second target power value of another NSSS module, thereby improving the accuracy of the power adjustment of the NSSS module.

[0108] For example, in the case where the power plant load deviation is positive, such as the power plant load deviation is 10% RFP. If the first value is 100% RFP and the first set power value of the first NSSS module is 80% RFP, which is greater than the second set power value of 65% RFP of the second NSSS module, then it can be determined that the first NSSS module is the target NSSS module. After that, the first difference can be determined as: 100% RFP - 80% RFP = 20% RFP. Since the power plant load deviation of 10% RFP is less than the first difference of 20% RFP, then at this time, the first target power value of the target NSSS module can be determined as: 80% RFP + 10% RFP = 90% RFP, that is, it is determined that the first target power value of the first NSSS module is: 90% RFP, that is, the first target power value of the first NSSS module is: 90% RFP, and the second target power value of the second NSSS module remains the second set power value: 65% RFP.

[0109] It should be noted that the above examples are only illustrative and cannot be used as limitations on the power plant load deviation, the first value, the first set power value, the second set power value, etc. in the embodiments of the present disclosure.

[0110] Step 207, in the case where the power plant load deviation is negative, determine the second difference between the second value and the set power value corresponding to the target NSSS module.

[0111] Among them, the second value can be a pre-set value, such as 60% RFP, 50% RFP, etc., and the present disclosure does not make any limitations thereto.

[0112] For example, if the limit value of the set power value of any NSSS module is: 50% RFP - 100% RFP, then the second value can be determined as 50% RFP; or, if the limit value of the set power value of any NSSS module is: 60% RFP - 100% RFP, then the second value can be determined as 60% RFP, etc., and the present disclosure does not make any limitations thereto.

[0113] Step 208, in the case where the power plant load deviation is less than the second difference, determine the second value as the first target power value of the target NSSS module.

[0114] Step 209, based on the first set power value, the second set power value, the first value, and the first difference, determine the second target power value of the other NSSS module except the target NSSS module.

[0115] For example, when the power station load deviation is -20% RFP, if the first set power value of the first NSSS module is 70% RFP and the second set power value of the second NSSS module is 65% RFP, then the second NSSS module can be determined as the target NSSS module. If the second value is 50% RFP, then the second difference is -15% RFP, which is greater than the power station load deviation of -20% RFP. At this time, "50% RFP" can be determined as the first target power value of the target NSSS module. Then, the second target power value of the other NSSS module, that is, the first NSSS module, can be determined as: 70% RFP - 20% RFP - 50% RFP + 65% RFP = 65% RFP.

[0116] It should be noted that the above examples are only illustrative and cannot be used as limitations on the power station load deviation, the first value, the first set power value, the second set power value, etc. in the embodiments of the present disclosure.

[0117] Step 210, when the power station load deviation is greater than or equal to the second difference, based on the second value, the first set power value, and / or the second set power value, determine the first target power value of the target NSSS module.

[0118] For example, when the power station load deviation is -20% RFP, if the first set power value of the first NSSS module is 70% RFP and the second set power value of the second NSSS module is 65% RFP, then the second NSSS module can be determined as the target NSSS module. If the second value is 50% RFP, then the second difference is -15% RFP, which is greater than the power station load deviation of -20% RFP. At this time, "50% RFP" can be determined as the first target power value of the target NSSS module. Then, the second target power value of the other NSSS module, that is, the first NSSS module, can be determined as: 70% RFP - 20% RFP - 50% RFP + 65% RFP = 65% RFP.

[0119] It should be noted that the above examples are only illustrative and cannot be used as limitations on the power station load deviation, the first value, the first set power value, the second set power value, etc. in the embodiments of the present disclosure.

[0120] It should be noted that the method for determining the reactor power of the high-temperature gas-cooled reactor nuclear power plant provided by the present disclosure can be applied to any high-temperature gas-cooled reactor nuclear power plant. The number of reactors can be 2, 6, etc. Only taking 2 reactors as an example for illustration, the method for determining the power of 6 reactors is similar and will not be elaborated here.

[0121] The following combines Figure 2AThe determination process of the reactor power of the high-temperature gas-cooled reactor nuclear power plant provided by the present disclosure will be briefly described with reference to Table 1.

[0122] First, the parameters used in the determination process of the reactor power of the high-temperature gas-cooled reactor nuclear power plant can be summarized as shown in Table 1:

[0123] Table 1

[0124]

[0125] As can be seen from Table 1, the first NSSS module, i.e., 1#NSSS, and the second NSSS module, i.e., 2#NSSS, can be configured with a power distributor in the high-temperature gas-cooled reactor nuclear power plant.

[0126] From Figure 2A it can be seen that when the first set power value Pt10 of 1#NSSS and Pt20 of 2#NSSS are both greater than the set value, for example, as shown in Table 1, when both Pt10 and Pt20 are greater than 50% RFP, it is determined that the power distributor can be allowed to be put into C1 at this time.

[0127] After that, power distribution C2 can be carried out only when both 1#NSSS and 2#NSSS are in steady-state operation. For example, as shown in Table 1, when the first deviation △Pt1 between Pt1 and Pt10 of 1#NSSS and the second deviation △Pt2 between Pt2 and Pt20 of 2#NSSS are both within (-5% RFP, +5% RFP), reactor power distribution can be allowed.

[0128] After meeting the conditions for the power distributor to be put in and power distribution to be allowed, it can be further determined to put the power distributor into manual mode or automatic mode.

[0129] For example, the power distributor can be determined to be put into manual mode or automatic mode by receiving an instruction. It can be understood that during automatic distribution, the maximum power distribution scheme can be followed, that is, the power distribution value of one reactor is preferentially guaranteed to reach 100% RFP.

[0130] When △Pt>0, that is, when the input grid load demand value is greater than the actual power value of the nuclear power plant unit, it can be determined that the reactor needs to increase the load at this time. The principle of automatic power distribution is to preferentially ensure that one reactor can operate at full power. Therefore, it can be first judged which NSSS module has a higher power, and the NSSS module with higher power is determined as the target NSSS module.

[0131] For example, when Pt10 ≥ Pt20, the 1# NSSS corresponding to Pt10 can be determined as the target NSSS module. Then, it can be further determined whether △Pt is greater than (100 - Pt10). If it is greater, then the first target power value of the 1# NSSS can be determined as: Pt10′ = 100, and the second target power value of the 2# NSSS can be determined as: Pt20′ = Pt20 + ΔPt - 100 + Pt10. If △Pt is less than or equal to (100 - Pt10), then the first target power value of the 1# NSSS can be determined as: Pt10′ = Pt10 + ΔPt, and the second target power value of the 2# NSSS can be determined as: Pt20′ = Pt20.

[0132] When Pt10 < Pt20, the 2# NSSS corresponding to Pt20 can be determined as the target NSSS module. Then, it can be further determined whether △Pt is greater than (100 - Pt20). If it is greater, then the first target power value of the 2# NSSS can be determined as: Pt20′ = 100, and the second target power value of the 1# NSSS can be determined as: Pt10′ = Pt10 + ΔPt - 100 + Pt20. If △Pt is less than or equal to (100 - Pt20), then the first target power value of the 2# NSSS can be determined as: Pt20′ = Pt20 + ΔPt, and the second target power value of the 1# NSSS can be determined as: Pt10′ = Pt10.

[0133] Alternatively, when △Pt < 0, that is, when the input grid load demand value is less than the actual power value of the unit, it can be determined that the reactor needs to be unloaded at this time. The NSSS module with a lower load can be unloaded first. When this module drops to 50% RFP, the remaining part of the load reduction is borne by another reactor.

[0134] For example, when Pt10 > Pt20, the 2# NSSS corresponding to Pt20 can be determined as the target NSSS module. Then, it can be further determined whether △Pt is less than (50 - Pt20). If it is less, then the first target power value of the 2# NSSS can be determined as: Pt20′ = 50, and the second target power value of the 1# NSSS can be determined as: Pt10′ = Pt10 + ΔPt - 50 + Pt20. If △Pt is greater than or equal to (50 - Pt20), then the first target power value of the 2# NSSS can be determined as: Pt20′ = Pt20 + ΔPt, and the second target power value of the 1# NSSS can be determined as: Pt10′ = Pt10.

[0135] When Pt10 is less than Pt20, the 1# NSSS corresponding to Pt10 can be determined as the target NSSS module. Then, it can be further determined whether △Pt is less than (50 - Pt10). If it is less, then at this time, the first target power value of the 1# NSSS can be determined as: Pt10′ = 50, and the second target power value of the 2# NSSS can be determined as: Pt20′ = Pt20 + ΔPt - 50 + Pt10. If △Pt is greater than or equal to (50 - Pt10), then at this time, the first target power value of the 1# NSSS can be determined as: Pt10′ = Pt10 + ΔPt, and the second target power value of the 2# NSSS can be determined as: Pt20′ = Pt20.

[0136] When performing reactor power distribution in manual mode, the received values can be determined as the manual setting values Pt10m and Pt20m corresponding to the 1# NSSS and the 2# NSSS respectively.

[0137] Furthermore, after determining the target power values corresponding to the 1# NSSS and the 2# NSSS respectively, they can also be verified: Pti0′ = min(Pti0, 100), Pti0′ = min(Pti0, 100). If the target power value of any NSSS is greater than 100, then the target power value of this any NSSS can be updated to: 100; if the target power value of any NSSS is less than 50, then the target power value of this any NSSS can be updated to: 50.

[0138] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the process of determining the target power value of the NSSS module in the embodiments of the present disclosure, etc.

[0139] In an embodiment of the present disclosure, the current power load deviation of the high-temperature gas-cooled reactor nuclear power plant, the current first thermal power value of the first nuclear steam supply system (NSSS) module in the high-temperature gas-cooled reactor nuclear power plant, the first set power value, the current second thermal power value of the second NSSS module, and the second set power value may be determined first. Then, in response to the first thermal power value, the first set power value, the second thermal power value, and the second set power value satisfying a preset condition, a target NSSS module is determined according to the power load deviation, the first set power value, and the second set power value. Then, when the power load deviation is positive, the first target power value of the target NSSS module and the second target power value of the other NSSS module are determined according to the first value and each power value. When the power load deviation is negative, the first target power value of the target NSSS module and the second target power value of the other NSSS module are determined according to the second value and each power value. Thus, the power load deviation, the first thermal power value, the first set power value, the second thermal power value, and the second set power value corresponding to the first NSSS and the second NSSS may be determined first. Then, when the preset condition is satisfied, the target power values of the two NSSS modules can be automatically determined according to the power load deviation and each power value of the NSSS module. This process can be realized without manual operation, thereby not only reducing the labor cost, but also improving the efficiency of reactor power configuration.

[0140] To implement the above embodiment, the present disclosure also proposes a device for determining the reactor power of a high-temperature gas-cooled reactor nuclear power plant.

[0154] Optionally, the third determination module 130 is specifically configured to:

[0155] When the power plant load deviation is positive, determine a first difference between a first value and the set power value corresponding to the target NSSS module;

[0156] When the power plant load deviation is greater than the first difference, determine the first value as the first target power value of the target NSSS module;

[0157] Based on the first set power value, the second set power value, the first value, and the first difference, determine the second target power value of another NSSS module other than the target NSSS module.

[0158] Optionally, the third determination module 130 is specifically configured to:

[0159] When the power station load deviation is less than or equal to the first difference value, based on the first value, the first set power value, and / or the second set power value, determine the first target power value of the target NSSS module.

[0160] Optionally, the third determination module 130 is specifically configured to:

[0161] When the power station load deviation is negative, determine the second difference value between the second value and the set power value corresponding to the target NSSS module;

[0166] For the functions and specific implementation principles of the above-mentioned modules in the embodiments of the present disclosure, reference may be made to the above-mentioned method embodiments, and details are not described herein again.

[0167] The device for determining the reactor power of a high-temperature gas-cooled reactor nuclear power plant according to an embodiment of the present disclosure can first determine the current power plant load deviation of the high-temperature gas-cooled reactor nuclear power plant, the current first thermal power value of the first nuclear steam supply system (NSSS) module in the high-temperature gas-cooled reactor nuclear power plant, the first set power value, as well as the current second thermal power value of the second NSSS module and the second set power value. Then, in response to the first thermal power value, the first set power value, the second thermal power value, and the second set power value satisfying a preset condition, the target NSSS module is determined according to the power plant load deviation, the first set power value, and the second set power value. Next, according to the relationship between the power plant load deviation and the target power value corresponding to the target NSSS module, the first target power value of the target NSSS module and the second target power value of the other NSSS module except the target NSSS module are determined. Thus, the power plant load deviation, the first thermal power value, the first set power value, the second thermal power value, and the second set power value corresponding to the first NSSS and the second NSSS can be determined first. Then, when the preset condition is satisfied, the target power values of the two NSSS modules can be automatically determined according to the power plant load deviation and the respective power values of the NSSS modules. This process can be realized without manual operation, thereby not only reducing the labor cost but also improving the efficiency of reactor power configuration.

Then, in response to the first thermal power value, the first set power value, the second thermal power value, and the second set power value satisfying a preset condition, the target NSSS module is determined according to the power load deviation, the first set power value, and the second set power value. Next, according to the relationship between the power load deviation and the target power value corresponding to the target NSSS module, the first target power value of the target NSSS module and the second target power value of another NSSS module other than the target NSSS module are determined. Thus, the power load deviation, the first thermal power value, the first set power value, the second thermal power value, and the second set power value corresponding to the first NSSS and the second NSSS can be first determined. Then, when the preset condition is satisfied, the target power values of the two NSSS modules can be automatically determined according to the power load deviation and the respective power values of the NSSS modules. This process can be realized without manual operation, thereby not only reducing the labor cost but also improving the efficiency of reactor power configuration.
