TECHNICAL FIELD

[0001] The present application relates to the technical field of nuclear reactors, and particularly relates to a control method and device for a turbine bypass discharge valve. BACKGROUND

[0002] In a normal operation transient of a nuclear power plant, when the load of a turbine changes, a steam bypass discharge valve often needs to be controlled to discharge excess steam to provide a temporary heat sink for a reactor primary loop, continuously leading out the heat of the reactor, thereby protecting the safety of the nuclear reactor.

[0003] A conventional control method for a turbine bypass discharge valve usually detects changes in the average temperature of a primary loop or changes in a secondary loop steam pipe caused by mismatching of changes in load and changes in the thermal power of a nuclear reactor after changes in the load of a turbine and changes in the thermal power of the nuclear reactor, generates a corresponding control signal according to the result of detecting the changes, and sends the control signal to a valve positioner of the corresponding bypass discharge valve to control the opening of the valve by the valve positioner.

[0004] However, the above-mentioned control method for a turbine bypass discharge valve has the problem of low control efficiency. SUMMARY

[0019] If the thermal power data is greater than the preset thermal power data threshold, a third level signal is generated;

[0020] If the thermal power data is less than or equal to the preset thermal power data threshold, a fourth level signal is generated.

[0021] In one embodiment, a valve control signal is generated based on a first response signal and a second response signal, including:

[0022] When the first response signal is a first level signal and the second response signal is a third level signal, a target valve control signal is generated based on the first level signal and the third level signal.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] During the transient operation of a nuclear power plant, when the turbine load changes, it is often necessary to control the steam bypass discharge valve to release excess steam, providing a temporary heat sink for the reactor primary loop, continuously removing heat from the reactor, and thus protecting the safety of the nuclear reactor.

[0042] The traditional method for controlling bypass discharge valves in steam turbines typically involves detecting changes in the turbine load and nuclear reactor thermal power. This is done after detecting a mismatch between the load change and the reactor thermal power, resulting in a change in the primary loop average temperature or a change in the secondary loop steam pipes. Based on the detected changes, a corresponding control signal is generated and sent to the valve positioner of the corresponding bypass discharge valve. The valve positioner then controls the opening of the valve.

[0043] For example, taking the generation of control signals by observing changes in the average temperature of the primary loop caused by changes in load and nuclear reactor thermal power as an example, in this process, it is necessary to wait for the load change to be detected over a period of time, and then detect the change in thermal power in order to detect the change in the average temperature of the coolant in the primary loop, and finally generate a control signal based on this. The method for generating control signals by changes in the secondary loop steam pipes is similar. Both of these methods require too much time to generate control signals, resulting in low control efficiency.

[0044] In view of this, this application provides a method and apparatus for controlling a turbine bypass discharge valve. It acquires the current thermal power data of the nuclear reactor and the current load data of the corresponding turbine. Then, based on the thermal power and load data, a valve control signal is generated, thereby determining whether to open the turbine bypass discharge valve. In this way, the valve control signal for controlling the opening of the bypass discharge valve is directly generated from the real-time acquired thermal power and load data, eliminating the need to wait for changes in load and thermal power and to continuously observe their impact on the turbine circuit. This reduces waiting time and improves the efficiency of valve opening control.

[0045] The turbine bypass discharge valve control method provided in this application embodiment can be applied to, for example... Figure 1 The application environment shown is illustrated. The data storage system stores the data that server 101 needs to process. The data storage system can be integrated onto server 101, or it can be located on the cloud or other network servers. Server 101 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0046] In one exemplary embodiment, such as Figure 2 As shown, a method for controlling a turbine bypass discharge valve is provided, which is applied to... Figure 1 Taking server 101 as an example, the explanation includes the following steps 201 to 203. Wherein:

[0047] Step 201: Obtain the current thermal power data of the nuclear reactor and the current load data of the turbine corresponding to the nuclear reactor.

[0048] Thermal power data can be the numerical value corresponding to the thermal power generated by the nuclear reactor during the nuclear reaction. Optionally, sensors can be installed at multiple preset locations in the nuclear reactor, so that the server can obtain the current thermal power data of the nuclear reactor through the signals transmitted by the sensors. Optionally, the server can obtain thermal power data detected by other devices from the database.

[0049] In this embodiment, the nuclear reactor may correspond to at least one operating steam turbine. The load data of the steam turbine is the power data that the steam turbine needs to output. In this embodiment, the server can detect the current load data through various load detection devices. The load detection devices can be set according to the actual application scenario. Taking the steam turbine outputting electrical energy as an example, the load detection devices can be current sensors, voltage sensors, etc. Optionally, the server can obtain the current load data through the detection signal output by the load detection device. Optionally, the load data detected by the load detection device will be uploaded to the database in real time, and the server can obtain the current load data from the database.

[0050] Step 202: Generate valve control signals based on thermal power data and load data.

[0051] In this embodiment, when the load data is too low and the thermal power data is too high, in order to prevent the reactor secondary loop heat sink from being lost rapidly, it is necessary to open the turbine bypass discharge valve to discharge excess steam, thereby alleviating the overheating of the reactor primary loop and ensuring that the reactor operates within the allowable range.

[0052] Therefore, in one possible implementation, the server can calculate the difference between thermal power data and load data. If the difference exceeds a threshold, the server can generate a target valve control signal that instructs the bypass discharge valve to be opened; otherwise, it generates other valve control signals.

[0053] In another possible implementation, the server can input thermal power data and load data into a pre-trained signal generation model, thereby controlling the signal through the model valve.

[0054] Step 203: Determine whether to open the bypass discharge valve of the steam turbine based on the valve control signal.

[0055] Once the valve control signal is generated, the server can determine whether to open the turbine bypass discharge valve based on the valve control signal. In one possible implementation, the server can determine whether to open the turbine bypass discharge valve based on the level of the valve control signal. Optionally, when the server detects that the valve control signal is a high-level signal (value 1), the server can determine that the valve control signal is used to indicate that the bypass discharge valve should be opened; alternatively, when the server detects that the valve control signal is a low-level signal (value 0), the server can determine that the valve control signal indicates that the bypass discharge valve should not be opened.

[0056] In one possible implementation, after receiving the valve control signal, the server can bypass the valve positioner corresponding to the bypass discharge valve and directly send the valve control signal to the bypass discharge valve to quickly complete the control of the bypass discharge valve and improve control efficiency.

[0057] In this embodiment of the application, during the process of controlling the valve, the server can detect in real time whether there are any abnormalities in the thermal power data and load data after the bypass discharge valve is opened. If so, the server can perform preset operations to protect the safety of the nuclear reactor turbine.

[0058] In the above embodiments, the valve control signal for controlling whether the bypass discharge valve is opened is directly generated by the real-time acquired current thermal power data and load data. There is no need to wait for changes in load and thermal power to occur and continue to observe the impact of these changes on the turbine circuit, which reduces the waiting time and improves the efficiency of valve opening control.

[0059] In one embodiment, based on the above Figure 2 The illustrated embodiment can be found in [reference]. Figure 3 This embodiment relates to the process of generating valve control signals based on thermal power data and load data. For example... Figure 3 As shown, step 202 may include steps 301 to 303.

[0060] Step 301: Generate a first response signal based on the deviation between the thermal power data and the load data.

[0061] In one possible implementation, the server can generate a first response signal based on the deviation between the thermal power data and the load data. The first response signal can be a first level signal or a second level signal. The server can then calculate the difference between the thermal power data and the load data and determine the power deviation value based on the difference. If the power deviation value is greater than a preset deviation threshold, the first level signal is generated. If the power deviation value is less than or equal to the preset deviation threshold, the second level signal is generated.

[0062] In this embodiment, the power deviation value can be used to characterize the degree of deviation between the thermal power and the load data. The power deviation value can be determined based on the difference between the thermal power data and the load data. The specific calculation formula can be found in formula (1):

[0063] Power deviation value = (heat power data - load data) / 100 (unit: %) (1)

[0064] When the power deviation value is greater than the preset deviation threshold, it means that the deviation is too large. At this time, it is necessary to open the bypass discharge valve to release the excess steam. In this embodiment, the first level signal can be set to a high level signal (value is 1) to characterize that the power deviation value is too large, and the second level signal can be set to a low level signal (value is 0) to characterize that the power deviation value is still within the preset deviation threshold.

[0065] Step 302: Generate a second response signal based on the thermal power data.

[0066] In one possible implementation, the second response signal is a third-level signal or a fourth-level signal. The server can then compare the thermal power data with a preset thermal power data threshold. If the thermal power data is greater than the preset thermal power data threshold, a third-level signal is generated. If the thermal power data is less than or equal to the preset thermal power data threshold, a fourth-level signal is generated.

[0067] In this embodiment, when the thermal power data is too high, the steam turbine may not be able to bear the load. At this time, it is also necessary to open the bypass discharge valve to release the excess steam. In this embodiment, the third level signal can be set to a high level signal (value is 1) to indicate that the thermal power data is too high, and the fourth level signal can be set to a low level signal (value is 0) to indicate that the thermal power data is still within the safe value range (preset thermal power data threshold).

[0068] Step 303: Generate a valve control signal based on the first response signal and the second response signal.

[0069] Based on the above embodiments, in one possible implementation, the server can set an AND gate between the first response signal and the second response signal, that is, when the first response signal is a first level signal and the second response signal is a third level signal, the server can generate a target valve control signal based on the first level signal and the third level signal.

[0070] In this embodiment, the target valve control signal can be used to characterize that the current power deviation value is too large and the thermal power data is too large; that is, the target valve control signal can be used to indicate that the bypass discharge valve is opened.

[0071] In this embodiment of the application, when the current power deviation value is too large and the thermal power data is too large, the server needs to quickly open the bypass discharge valve to ensure the safety of the turbine and the nuclear reactor. In this case, the server can send the target valve control signal to the bypass discharge valve, wherein the target valve control signal is used to control the bypass discharge valve to open.

[0072] In this way, the server directly bypasses the valve positioner to control the opening of the bypass discharge valve, improving the efficiency of controlling the opening of the bypass discharge valve.

[0073] In one embodiment, refer to Figure 4 An exemplary method for controlling a turbine bypass discharge valve is provided. This method is used in a server and can be applied to... Figure 1 The implementation environment shown.

[0074] Step 401: Obtain the current thermal power data of the nuclear reactor and the current load data of the turbine corresponding to the nuclear reactor.

[0075] Step 402: Calculate the difference between the thermal power data and the load data, and determine the power deviation value based on the difference.

[0076] Step 403: If the power deviation value is greater than the preset deviation threshold, then generate the first level signal.

[0077] Step 404: If the power deviation value is less than or equal to the preset deviation threshold, then a second level signal is generated.

[0078] The first response signal is either a first-level signal or a second-level signal.

[0079] Step 405: If the thermal power data is greater than the preset thermal power data threshold, then a third level signal is generated.

[0080] Step 406: If the thermal power data is less than or equal to the preset thermal power data threshold, then a fourth level signal is generated.

[0081] The second response signal is either a third-level signal or a fourth-level signal.

[0082] Step 407: When the first response signal is a first level signal and the second response signal is a third level signal, generate a target valve control signal based on the first level signal and the third level signal.

[0083] The target valve control signal is used to instruct the bypass discharge valve to be opened.

[0084] Step 408: Determine whether to open the bypass discharge valve of the steam turbine based on the valve control signal.

[0085] Step 409: Send the target valve control signal to the bypass discharge valve. The target valve control signal is used to control the bypass discharge valve to open.
