[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

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

[0042] The control method of the bypass discharge valve in the traditional steam turbine is usually to detect the change of the average temperature of the primary circuit or the change of the steam pipeline of the secondary circuit caused by the mismatch between the load change and the change of the thermal power of the nuclear reactor after the load of the steam turbine changes and the thermal power of the nuclear reactor changes, and then generate a corresponding control signal according to the result of the detection change, and then send the control signal to the valve positioner of the corresponding bypass discharge valve, and control the opening of the valve through the valve positioner.

[0043] For example, taking the generation of a control signal by observing the change in the average temperature of a circuit caused by the change in load and the change in the thermal power of the nuclear reactor, in this process, it is necessary to wait for the change in load to be detected for a period of time, and then detect the change in thermal power, so as to detect the change in the average temperature of the coolant in the first circuit, and finally generate a control signal based on this; the method of generating a control signal by the change in the steam pipeline of the second circuit is similar. The time required for both to generate control signals is too long, and there is a problem of low control efficiency.

[0044] In view of this, the present application provides a method, device, equipment, readable storage medium and program product for controlling a bypass discharge valve of a steam turbine, which obtains the current thermal power data of a nuclear reactor and the current load data of a steam turbine corresponding to the nuclear reactor, and then generates a valve control signal according to the thermal power data and the load data, thereby determining whether to open the bypass discharge valve of the steam turbine according to the valve control signal. In this way, a valve control signal for controlling whether the bypass discharge valve is opened is directly generated by the current thermal power data and load data obtained in real time, without waiting for changes in the load and thermal power to be detected, and continuing to observe the impact of the changes in the two on the steam turbine circuit, thereby reducing the waiting time and improving the efficiency of controlling the opening of the valve.

[0045] The turbine bypass discharge valve control method provided in the embodiment of the present application can be applied in the application environment as shown in FIG1. ​​Among them, the data storage system can store the data that the server 101 needs to process. The data storage system can be integrated on the server 101, or it can be placed on the cloud or other network servers. The server 101 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0046] In an exemplary embodiment, Figure 2 As shown, a method for controlling a steam turbine bypass discharge valve is provided, and the method is applied to the server 101 in FIG. 1 as an example for description, including the following steps 201 to 203. Among them:

[0047] Step 201, obtaining the current thermal power data of the nuclear reactor, and obtaining the current load data of the steam turbine corresponding to the nuclear reactor.

[0048] The thermal power data may be a numerical value corresponding to the thermal power generated when a nuclear reactor performs a nuclear reaction. Optionally, sensors may be installed at multiple preset positions of the nuclear reactor so that the server may obtain the current thermal power data of the nuclear reactor through signals transmitted by the sensors; optionally, the server may obtain thermal power data detected by other devices from a database.

[0049] In an embodiment of the present application, a nuclear reactor may correspond to at least one operating steam turbine, and the load data of the steam turbine is the power data that the steam turbine needs to output. In an embodiment of the present application, the server may detect the current load data through a variety of load detection devices. The load detection device may be set according to the actual application scenario. Taking the output of the steam turbine as an example, the load detection device may be a current sensor, a voltage sensor, etc. Optionally, the server may 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 may be uploaded to a database in real time, and the server may obtain the current load data from the database.

[0050] Step 202: Generate a valve control signal according to the thermal power data and the load data.

[0051] In an embodiment of the present application, when the load data is too low and the thermal power data is too high, in order to avoid the rapid loss of the heat sink in the secondary circuit of the reactor, it is necessary to open the turbine bypass discharge valve to discharge excess steam, thereby alleviating the overheating of the first circuit of the reactor and ensuring that the reactor operates within the allowable range.

[0052] Therefore, in one possible implementation, the server may calculate the difference between the thermal power data and the load data. If the difference exceeds a threshold, the server may generate a target valve control signal instructing to open the bypass exhaust valve; otherwise, other valve control signals may be generated.

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

[0054] Step 203, determining whether to open the bypass discharge valve of the steam turbine according to the valve control signal.

[0055] After the valve control signal is generated, the server can determine whether to open the bypass drain valve of the steam turbine according to the valve control signal. In a possible implementation, the server can determine whether to open the bypass drain valve of the steam turbine according to the level of the valve control signal. Optionally, when the server detects that the valve control signal is a high-level signal (value is 1), the server can determine that the valve control signal is used to indicate opening the bypass drain valve; optionally, when the server detects that the valve control signal is a low-level signal (value is 0), the server can determine that the valve control signal indicates not to open the bypass drain valve.

[0056] In a possible implementation, after receiving the valve control signal, the server may skip 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 the control efficiency.

[0057] In an embodiment of the present 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 execute preset operations to protect the safety of the nuclear reactor turbine.

[0058] In the above embodiment, a valve control signal for controlling whether the bypass discharge valve is opened is directly generated by obtaining the current thermal power data and load data in real time. There is no need to wait for changes in the load and thermal power to be detected, and continue to observe the impact of the changes in the two on the turbine circuit, thereby reducing waiting time and improving the efficiency of controlling the valve opening.

[0059] In one embodiment, based on the above Figure 2 The embodiment shown, see Figure 3 This embodiment relates to a process of generating a valve control signal based on thermal power data and load data. Figure 3 As shown, step 202 may include steps 301 to 303 .

[0060] Step 301: Generate a first response signal according to the thermal power data and the deviation of the load data.

[0061] In one possible implementation, the server may generate a first response signal based on the deviation between the thermal power data and the load data, wherein the first response signal may be a first level signal or a second level signal. The server may 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, a first level signal is generated; if the power deviation value is less than or equal to the preset deviation threshold, a second level signal is generated.

[0062] In the embodiment of the present application, 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 according to the difference between the thermal power data and the load data. The specific calculation formula can refer to formula (1):

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

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

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

[0066] In one possible embodiment, the second response signal is a third level signal or a fourth level signal, and the server can 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 an embodiment of the present application, when the thermal power data is too large, 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 excess steam. In an embodiment of the present application, the third level signal can be set to a high level signal (value is 1), which is used to characterize that the thermal power data is too large, and the fourth level signal is a low level signal (value is 0), which can be used to characterize that the thermal power data is still within a safe value range (preset thermal power data threshold).

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

[0069] Based on the above embodiments, in a possible implementation manner, the server may 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 may generate a target valve control signal based on the first level signal and the third level signal.

[0070] In the embodiment of the present application, the target valve control signal can be used to indicate 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 opening of the bypass exhaust valve.

[0071] In an embodiment of the present 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 drain valve to ensure the safety of the turbine and the nuclear reactor. The server can send a target valve control signal to the bypass drain valve, wherein the target valve control signal is used to control the opening of the bypass drain valve.

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

[0073] In one embodiment, referring to Figure 4 , provides an exemplary turbine bypass discharge valve control method, which is used for a server and can be applied in the implementation environment shown in FIG. 1 .

[0074] Step 401, obtaining the current thermal power data of the nuclear reactor, and obtaining the current load data of the steam turbine corresponding to the nuclear reactor.

[0075] Step 402, calculating the difference between the thermal power data and the load data, and determining the power deviation value according to the difference.

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

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

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

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

[0081] The second response signal is 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 according to the first level signal and the third level signal.

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

[0084] Step 408, determining whether to open the bypass discharge valve of the steam turbine according to the valve control signal.

[0085] Step 409 , sending a target valve control signal to the bypass drain valve, where the target valve control signal is used to control the bypass drain valve to open.
