Detailed Description

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

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

The disclosed embodiment is exemplified by the method for determining reactor power of a high temperature gas-cooled reactor nuclear power plant being configured in a device for determining reactor power of a high temperature gas-cooled reactor nuclear power plant, which may be applied to any computer device, so that the computer device may perform the function of determining reactor power of a high temperature gas-cooled reactor nuclear power plant.

The Computer device may be a Personal Computer (PC), a cloud device, a mobile device, and the like, and the mobile device may be a hardware device having various operating systems, touch screens, and/or display screens, such as a mobile phone, a tablet Computer, a Personal digital assistant, a wearable device, and an in-vehicle device.

Fig. 1 is a schematic flow chart of a method for determining reactor power of a high temperature gas cooled reactor nuclear power plant according to an embodiment of the present disclosure.

As shown in fig. 1, the method for determining reactor power of a high temperature gas cooled reactor nuclear power plant may include the following steps:

step 101, determining a current power station load deviation of the high temperature gas cooled reactor nuclear power plant, a current first thermal power value and a current first set power value of a first nuclear steam supply system NSSS module in the high temperature gas cooled reactor nuclear power plant, and a current second thermal power value and a current second set power value of a second NSSS module.

Among them, a Nuclear Steam Supply System (NSSS) is a system for generating steam using nuclear energy in a high temperature gas cooled reactor nuclear power plant, and functions as a boiler steam system in a thermal power plant. Generally, one NSSS may be provided in the high temperature gas cooled reactor nuclear power plant, or a plurality of NSSS may be provided, such as two, six, etc., which is not limited by the disclosure.

In addition, the first thermal power value may be understood as a current thermal power value of the first NSSS module; the first set power value may be understood as a current set power value of the first NSSS module, such as a set expected value, and the like, which is not limited by the disclosure.

In addition, the second thermal power value may be understood as the current thermal power value of the second NSSS module; the second set power value may be understood as a current set power value of the second NSSS module, such as a set expected value, and the like, which is not limited by the disclosure.

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

The power grid load demand value may be input by a user through a terminal device, or may also be a numerical value determined by analyzing a current power grid side demand, and the like, which is not limited in this disclosure.

For example, if the grid load demand is Pe0, the first set power value is Pt10, and the second set power value is Pt20, the station load deviation can be expressed as: Δ Pt =2Pe0- (Pt 10+ Pt 20).

Step 102, in response to that the first thermal power value, the first set power value, the second thermal power value and the second set power value meet a preset condition, determining a target NSSS module according to the power station load deviation, the first set power value and the second set power value.

The preset condition may be understood as a preset condition, and generally, 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 may be considered that the current first NSSS and the current second NSSS are both in a steady-state process, and at this time, the dual-reactor power distribution may be performed without affecting the operation of the high temperature gas cooled reactor nuclear power station.

Optionally, it may be determined that the preset condition is satisfied under the condition that a first deviation between the first thermal power value and the first set power value and a second deviation between the second thermal power value and the second set power value are both between the first threshold and the second threshold.

Wherein the first threshold and the second threshold may be predetermined values, for example, the first threshold may be 5% RFP and the second threshold may be-5% RFP; alternatively, the first threshold is-3% RFP, the second threshold can be 3% RFP, and so forth, as the present disclosure does not limit thereto.

In addition, the first deviation may be a difference between the first thermal power value and the first set power value, the second deviation may be a difference between the second thermal power value and the second set power value, and the like, which is not limited in this disclosure.

It is understood that the thermal power value may be larger than the set power value, or the thermal power value may also be larger than the set power value, etc., so that the first deviation and the second deviation may be positive values, or may also be negative values, etc., which is not limited by the disclosure.

For example, in the case where the first threshold is +6% RFP, the second threshold is-6% RFP, if the first deviation is 4% RFP, the second deviation is-1% RFP, both of which are between the first threshold and the second threshold, then it may be determined that the preset condition is currently satisfied, the reactor power allocation may be performed, and so on, without being limited thereto by the present disclosure.

Optionally, the NSSS module corresponding to the larger power value of the first set power value and the second set power value may be determined as the target NSSS module when the power station load deviation is a positive value; or, when the power station load deviation is a negative value, the NSSS module corresponding to the smaller power value of the first set power value and the second set power value is determined as the target NSSS module.

It can be understood that, if the power station load deviation is a positive value, it can be considered that the current thermal power value of the nuclear power station cannot meet the power grid load demand, and at this time, the reactor can be subjected to load-up operation. 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 module, the first NSSS module may be determined as the target NSSS module.

Or, when the power station load deviation is a negative value, the input power grid load demand may be considered to be smaller than the current thermal power value of the nuclear power station, and at this time, the reactor may be subjected to load shedding operation. 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 module, the second NSSS module may be determined as the target NSSS module.

It should be noted that the above examples are only illustrative and should not be taken as a limitation on the manner of determining the target NSSS module in the embodiment of the present disclosure.

Step 103, determining a first target power value of the target NSSS module and a second target power value of another NSSS module except the target NSSS module according to a relationship between the power station load deviation and the target power value corresponding to the target NSSS module.

For example, in the case where the plant load deviation is positive and the target NSSS module is the first NSSS module, if the plant load deviation Δ Pt is 30% rfp, the target NSSS module is 70% rfp, and the second NSSS module is 30% rfp, then the first target power value for the target NSSS module may be determined to be: 70% FRP +30% RFP, the second NSSS module is 30% RFP.

Alternatively, in the case where the plant load deviation is negative and the target NSSS module is the first NSSS module, if the plant load deviation Δ Pt is-5% rfp, the target NSSS module is 60% rfp, and the second NSSS module is 70% rfp, then the first target power value for the target NSSS module may be determined as: 60% FRP-5% RFP and the second NSSS module 70% RFP.

It should be noted that the above examples are only illustrative, and should not be taken as limitations for determining the first target power value, the second target power value, and the like in the embodiments of the present disclosure.

Therefore, in the embodiment of the disclosure, the target NSSS module can be determined according to the load deviation of the power station, 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 the other NSSS module can be determined.

According to the embodiment of the disclosure, a current power station load deviation of the high temperature gas cooled reactor nuclear power plant, a current first thermal power value and a current first set power value of a first nuclear steam supply system NSSS module in the high temperature gas cooled reactor nuclear power plant, and a current second thermal power value and a current second set power value of a second NSSS module may be determined, then, in response to that the first thermal power value, the first set power value, the second thermal power value and the second set power value satisfy a preset condition, a target NSSS module may be determined according to the power station load deviation, the first set power value and the second set power value, and then, a first target power value of the target NSSS module and a second target power value of another NSSS module except the target NSSS module may be determined according to a relationship between the power station load deviation and the target power value corresponding to the target NSSS module. Therefore, the first thermal power value, the first set power value, the second thermal power value and the second set power value which correspond to the power station load deviation, the first NSSS and the second NSSS respectively can be determined firstly, and then when the preset condition is met, the target power values of the two NSSS modules can be automatically determined according to the power station load deviation and the power values of the NSSS modules.

Fig. 2 is a schematic flow chart of a method for determining reactor power of a high temperature gas cooled reactor nuclear power plant according to an embodiment of the present disclosure.

As shown in fig. 2, the method for determining reactor power of a high temperature gas cooled reactor nuclear power plant may include the following steps:

step 201, determining a current power station load deviation of the high temperature gas cooled reactor nuclear power plant, a current first thermal power value and a current first set power value of a first nuclear steam supply system NSSS module in the high temperature gas cooled reactor nuclear power plant, and a current second thermal power value and a current second set power value of a second NSSS module.

Step 202, in response to that the first thermal power value, the first set power value, the second thermal power value, and the second set power value satisfy the preset condition, determining a target NSSS module according to the power station load deviation, the first set power value, and the second set power value.

Optionally, the NSSS module corresponding to the larger power value of the first set power value and the second set power value may be determined as the target NSSS module when the load deviation of the power station is a positive value; and under the condition that the load deviation of the power station is a negative value, determining the NSSS module corresponding to the smaller power value in the first set power value and the second set power value as a target NSSS module.

Step 203, determining a first difference value between the first value and the set power value corresponding to the target NSSS module when the power station load deviation is a positive value.

The first value may be a predetermined value, such as 100% RFP, 98% RFP, or the like. For example, if the limit 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 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., which the disclosure does not limit.

For example, if the target NSSS module is the second module, with the first value being 100% rfp, its corresponding set power value is 80% rfp, with the first difference therebetween being 20% rfp, the disclosure is not so limited.

And 204, determining the first value as a first target power value of the target NSSS module under the condition that the power station load deviation is larger than the first difference value.

For example, in the case where the first value is 100% rfp, if the target NSSS module is the second module, if the plant load deviation is 40% rfp, the first difference is 20% rfp, then the 100% rfp may be determined as the first target power value for the target NSSS module, i.e., the first target power value for the second NSSS module is 100% rfp, etc., which the disclosure does not limit.

Step 205, a second target power value of another NSSS module except the target NSSS module is determined based on the first set power value, the second set power value, the first value and the first difference.

For example, in the case where the plant load deviation is positive, such as 20% rfp, if the first value is 100% rfp, the first set power value 90% rfp for the first NSSS module is greater than the second set power value 65% rfp for the second NSSS module, then the first NSSS module may be determined to be the target NSSS module, and the first difference may be determined thereafter: 100% rfp-90% rfp =10% rfp. Since the plant load deviation 20%: 100% rfp, i.e., determining the first target power value for the first NSSS module as: 100% RFP. A second target power value for the other NSSS module, i.e., the second NSSS module, may then be determined to be: the 65% RFP +20% RFP-100% by weight RFP +90% RFP =75% RFP.

It should be noted that the above examples are only illustrative, and should not be taken as limitations of the station load deviation, the first value, the first set power value, the second set power value, and the like in the embodiments of the present disclosure.

And step 206, under the condition that the power station load deviation is smaller than or equal to the first difference, determining a first target power value of the target NSSS module based on the first value, the first set power value and/or the second set power value.

It can be understood that, when the power station load deviation is smaller than or equal to the first difference, the power station load requirement can be satisfied only by performing the load-up operation on the first target power value of the target NSSS module, without adjusting the second target power value of another NSSS module, thereby improving the accuracy of power adjustment of the NSSS module.

For example, in the case where the plant load deviation is positive, such as 10% rfp, if the first value is 100% rfp, the first set power value 80% rfp for the first NSSS module is greater than the second set power value 65% rfp for the second NSSS module, then the first NSSS module may be determined to be the target NSSS module, and the first difference may be determined thereafter: 100% RFP-80% RFP = -20% RFP. Since the plant load deviation 10%RFP, which is smaller than the first difference 10%: 80% RFP +10% RFP, i.e. determining the first target power value for the first NSSS module as: 90% rfp, i.e. the first target power value for the first NSSS module is: 90% rfp, the second target power value for the second NSSS module is still the second set power value: 65% RFP.

It should be noted that the above examples are only illustrative, and should not be taken as limitations on the station load deviation, the first numerical value, the first setting power value, the second setting power value, and the like in the embodiments of the present disclosure.

And step 207, determining a second difference value between the second value and the set power value corresponding to the target NSSS module under the condition that the power station load deviation is a negative value.

The second value may be a predetermined value, such as 60% RFP, 50% RFP, etc., but the disclosure is not limited thereto.

For example, if the limit 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 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., which the disclosure does not limit.

And step 208, determining the second value as the first target power value of the target NSSS module under the condition that the power station load deviation is smaller than the second difference value.

Step 209 determines a second target power value of another NSSS module except the target NSSS module based on the first set power value, the second set power value, the first value and the first difference.

For example, at a power station the load deviation is: -20% rfp if the first set power value of the first NSSS module is: 70% rfp, the second set power value of the second NSSS module is: 65% rfp, then the second NSSS module may be determined to be the target NSSS module. If the second value is 50% RFP, then the second difference is: -15% rfp, which is greater than the plant load deviation-20% rfp, then the "50% rfp" can be determined as the first target power value for the target NSSS module at this time. Then, it may be determined that the second target power value of the other NSSS module, i.e., the first NSSS module, is: 70% RFP-20% RFP-50% RFP +65% RFP =65% RFP.

And step 210, determining a first target power value of the target NSSS module based on the second value, the first set power value and/or the second set power value under the condition that the power station load deviation is greater than or equal to the second difference value.

For example, at a power station the load deviation is: -20% rfp, if the first set power value of the first NSSS module is: 70% rfp, the second set power value for the second NSSS module is: 65% rfp, then the second NSSS module may be determined to be the target NSSS module. If the second value is 50% RFP, then the second difference is: -15% rfp, which is greater than the plant load deviation-20% rfp, then the "50% rfp" can be determined as the first target power value for the target NSSS module at this time. Then, it may be determined that the second target power value of the other NSSS module, i.e., the first NSSS module, is: 70% RFP-20% RFP-50% RFP +65% RFP =65% RFP.

It should be noted that the method for determining reactor power of a high temperature gas cooled reactor nuclear power plant provided by the present disclosure may be applied to any high temperature gas cooled reactor nuclear power plant, the number of reactors may be 2, 6, and so on, and only 2 reactors are taken as an example for description, and the method for determining reactor power of 6 reactors is similar, and is not described herein again.

The following briefly describes the process for determining the reactor power of the high temperature gas cooled reactor nuclear power plant provided by the present disclosure with reference to fig. 2A and table 1.

Firstly, parameters used in the process of determining the reactor power of the high temperature gas cooled reactor nuclear power plant may be summarized as shown in table 1:

TABLE 1

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 divider in the high temperature gas cooled reactor nuclear power plant.

As can be seen from fig. 2A, the first set power values Pt10 and 2 #nssspt20at 1 #nsssare both greater than the set value, such as shown in table 1, when both Pt10 and Pt20 are greater than 50% rfp, it is determined that the power splitter can be allowed to throw C1 at this time.

Thereafter, power distribution C2 can be performed when both 1# NSSS and 2# NSSS are operating in steady state. For example, as shown in Table 1, when the first deviation Δ Pt1 between Pt1 and Pt10 for 1# NSSS and the second deviation Δ Pt2 between Pt2 and Pt20 for 2# NSSS are both between (-5% RFP, +5% RFP), reactor power allocation may be allowed.

After the power divider input and power divider enable conditions are met, it may be further determined to input the power divider into the manual mode or the automatic mode.

For example, the power divider may be placed in a manual mode or an automatic mode as determined by the received instructions. It will be appreciated that in automatic allocation, a prioritized maximum power allocation scheme may be followed, i.e. priority is given to ensuring that the power allocation value of one reactor reaches 100% rfp.

When the delta Pt is larger than 0, namely the input power grid load requirement value is larger than the actual power value of the nuclear power plant unit, the reactor needs to be subjected to load increase at the moment. The principle of automatic power distribution is to preferentially ensure that one reactor can run at full power, so that which NSSS module has higher power can be judged first, and the NSSS module with higher power is determined as a target NSSS module.

For example, when Pt10 is greater than or equal to Pt20, 1 #nssscorresponding to Pt10 may be determined as the target NSSS module. It may be further determined whether Δ Pt is greater than (100-Pt 10), and if so, the first target power value of 1 #nsssmay be determined as: the second target power value of Pt10' =100,2# nsss is: pt20' = Pt20+ Δ Pt-100+ Pt10. If Δ Pt is less than or equal to (100-Pt 10), then the first target power value for 1# NSSS may be determined to be: the second target power value of Pt10' = Pt10+ Δ Pt,2 #nsesis: pt20' = Pt20.

When Pt10 is smaller than Pt20, the 2# NSSS corresponding to Pt20 may be determined as the target NSSS module. It may then be further determined whether Δ Pt is greater than (100-Pt 20), and if so, the first target power value for # 2 nsss may be determined as: the second target power value for Pt20' =100,1# nsss is: pt10' = Pt10+ Δ Pt-100+ Pt20. If Δ Pt is less than or equal to (100-Pt 20), then the first target power value for 2# NSSS may be determined to be: the second target power value for Pt20' = Pt20+ Δ Pt,1#nsss is: pt10' = Pt10.

Alternatively, when Δ Pt <0, i.e. the input grid load demand is less than the actual plant power, it may be determined that the reactor needs to be derated at this time, the lower NSSS module may be derated first, and when the module is derated to 50% rfp, the remaining load derated portion is taken up by the other reactor.

For example, when Pt10 is greater than Pt20, the 2# NSSS corresponding to Pt20 may be determined as the target NSSS module. It may then be further determined whether Δ Pt is less than (50-Pt 20), and if so, the first target power value for # 2 nsss may be determined as: the second target power value for Pt20' =50,1# nsss is: pt10' = Pt10+ Δ Pt-50+ Pt20. If Δ Pt is greater than or equal to (50-Pt 20), then the first target power value for 2# NSSS may be determined at this point to be: the second target power value for Pt20' = Pt20+ Δ Pt,1#nsss is: pt10' = Pt10.

When Pt10 is smaller than Pt20, the 1 #nssscorresponding to Pt10 may be determined as the target NSSS module. It may then be further determined whether Δ Pt is less than (50-Pt 10), and if so, the first target power value for 1 #nsssmay be determined at this time as: the second target power value for Pt10' =50,2# nsss is: pt20' = Pt20+ Δ Pt-50+ Pt10. If Δ Pt is greater than or equal to (50-Pt 10), then the first target power value for 1# NSSS may be determined to be: the second target power value for Pt10' = Pt10+ Δ Pt,2# nsss is: pt20' = Pt20.

When the reactor power distribution is performed in the manual mode, the received values may be determined as manual setting values Pt10m and Pt20m corresponding to 1# #nsssand 2# #nsss, respectively.

Further, after the target power values corresponding to 1# NSSS and 2# NSSS are determined, it may be verified that Pti0'= min (Pti 0, 100) and Pti0' = min (Pti 0, 100) if the target power value of any NSSS is greater than 100, the target power value of any NSSS may be updated to: 100, respectively; the target power value for any NSSS is less than 50, then the target power value for that NSSS may be updated to be: 50.

it should be noted that the above example is only an illustrative example, and cannot be taken as a limitation on the process of determining the target power value of the NSSS module in the embodiment of the present disclosure.

The embodiment of the disclosure may determine a current power station load deviation of the high temperature gas cooled reactor nuclear power plant, a current first thermal power value and a current first set power value of a first nuclear steam supply system NSSS module in the high temperature gas cooled reactor nuclear power plant, and a current second thermal power value and a current second set power value of a second NSSS module, then determine a target NSSS module according to the power station load deviation, the first set power value and the second set power value 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, and then determine a first target power value of the target NSSS module and a second target power value of another NSSS module according to the first value and each power value when the power station load deviation is a positive value, and determine a first target power value of the target NSSS module and a second target power value of another NSSS module according to the second value and each power value when the power station load deviation is a negative value. Therefore, the first thermal power value, the first set power value, the second thermal power value and the second set power value which correspond to the power station load deviation, the first NSSS and the second NSSS respectively can be determined firstly, then when the preset conditions are met, the target power values of the two NSSS modules can be automatically determined according to the power station load deviation and the power values of the NSSS modules, the process can be achieved without manual operation, therefore, the labor cost is reduced, and the efficiency of reactor power configuration is improved.
