Description

Technical Field

[0001] This invention relates to the field of nuclear power plant retrofitting technology, and more specifically, to a commissioning method, apparatus, and system for a nuclear power plant reactor top exhaust control cabinet. Background Technology

[0002] During the long-term phase of a nuclear power plant's operation under above-design-base-rate accidents, non-condensable gases can accumulate on the reactor pressure vessel top end caps, affecting the depressurization of the primary coolant loop and core reflooding. If these gases accumulate on the top of the steam generator U-tube, they can disrupt the natural circulation of the primary coolant loop, compromising nuclear safety. Some operating nuclear power plants in China are planning to add reactor pressure vessel top venting systems during unit overhauls. The pressure vessel top venting control cabinet is used to control the opening and closing of the pressure vessel top venting valves and collect information on the status of these valves in the field.

[0003] During the retrofit implementation, the installation progress of the reactor pressure vessel top cover vent valves and on-site temperature instruments consistently lags behind the installation progress of the pressure vessel top cover vent control cabinet. After completing the installation of the pressure vessel top cover vent control cabinet, the logic channel testing of the control cabinet is only conducted after the installation and wiring of the pressure vessel top cover vent valves are completed. For units with short overhaul durations, this may prevent the project from being completed within the stipulated time, affecting the normal startup and power generation of the nuclear power unit. Furthermore, if problems are found in the configuration logic during the testing process, it may be necessary to occupy the critical path time for handling.

[0004] The relevant technologies involve conducting control cabinet logic channel tests by short-circuiting, disconnecting wires, and measuring terminal output voltage at the input and output terminals of the control cabinet.

[0053] Figure 3 This is a schematic diagram of the circuit structure of the commissioning system for the exhaust control cabinet of the reactor top cover in a nuclear power plant, provided in an embodiment of the present invention. Detailed Implementation

[0054] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0055] like Figure 1 , 2 As shown, Figure 1 , 2 This is a flowchart of a commissioning method for a nuclear power plant reactor top exhaust control cabinet. In an embodiment of the commissioning method for a nuclear power plant reactor top exhaust control cabinet of the present invention, the following steps are included:

[0056] Action debugging steps:

[0057] S1-1: Receives the action debugging command output from the control cabinet, and triggers the simulated exhaust valve module to generate a position signal according to the action debugging command;

[0058] S1-2: The control cabinet receives position signals and performs logic processing to obtain the action debugging results;

[0059] Troubleshooting steps:

[0060] S2-1: Triggers fault debugging action and generates corresponding location fault signal;

[0061] S2-2: The control cabinet receives position fault signals and performs logic processing to obtain fault debugging results;

[0062] Get and display the results of action debugging or fault debugging.

[0063] like Figure 1 As shown, in some embodiments, the position signal includes a first open position state and a first closed position state; the action debugging steps also include steps S1-3: the control cabinet acquires and displays the first open position state and the first closed position state; and performs logical processing on the first open position state and the first closed position state to obtain the action debugging result.

[0064] like Figure 2 As shown, in some embodiments, the position fault signal includes a second open position state and a second closed position state; the fault debugging action includes steps S2-3: the control cabinet acquires and displays the second open position state and the second closed position state; and performs logical processing on the second open position state and the second closed position state to obtain the fault debugging result.

[0065] like Figure 3 The diagram shows the structure of the commissioning system for the exhaust control cabinet of a nuclear power plant reactor top cover provided by the present invention. It includes the structure of the commissioning device for the exhaust control cabinet of a nuclear power plant reactor top cover, comprising: a simulated exhaust valve module 110, a fault simulation module 120, and a signal module 130.

[0066] The simulated exhaust valve module 110 is used to receive and trigger actions based on the action debugging commands output by the control cabinet to generate position signals. When the exhaust valve of the reactor pressure vessel top cover lags behind the installation progress of the pressure vessel top cover exhaust control cabinet, the simulation of the opening and closing position of the exhaust valve of the pressure vessel top cover by the simulated exhaust valve module 110 can enable the logic channels of the control cabinet to be tested in advance, thereby optimizing the system schedule.

[0067] The fault simulation module 120 is used to trigger fault debugging actions and output corresponding location fault signals. The signal module 130 is used to acquire and display the action debugging results or fault debugging results output by the control cabinet to indicate whether the logic processing of the control cabinet is correct. By triggering a simulated exhaust valve fault through the fault simulation module 120 to perform fault debugging on the control cabinet, it is possible to realize the logic processing of the control cabinet when it receives an exhaust valve fault signal. The signal module can then determine whether the logic processing of the control cabinet is correct, thereby discovering whether there are any problems with the control cabinet logic in the process.

[0068] It should be noted that, Figure 3 The explanations of the letters or codes are as follows: DO1-48V, DO2-24V, DO3-24V, DI1, DI2, DI3, DI4 are the output and input terminals of the control cabinet; LA is the indicator light; KM1, KM2 are the relay coils; KM1-NC, KM2-NC are the normally closed contacts of the relay; KM1-NO, KM2-NO are the normally open contacts of the relay; SB1, SB2, SB3, SB4 are the buttons.

[0069] like Figure 3 As shown, in some embodiments, the simulated exhaust valve module 110 includes: a trigger unit 111 connected to the output end of the control cabinet, and a signal generation unit 112 connected to the input end of the control cabinet.

[0070] Trigger unit 111 is used to receive and trigger the generation of an action signal according to the action debugging command. Signal generation unit 112 is used to receive the action signal and generate an action to produce a corresponding position signal. Trigger unit 111 and signal generation unit 112 are linked in action.

[0071] In the embodiments provided by the present invention, the simulated exhaust valve module 110 includes a voltage relay; the triggering unit 111 includes a coil of the voltage relay; the signal generating unit 112 includes a normally open contact and a normally closed contact of the voltage relay; the position signal includes a first open position state and a first closed position state.

[0072] The coil is used to receive and trigger an action signal according to the action debugging command; the normally closed contact is used to receive and open according to the action signal to provide the first closed position state; the normally open contact is used to receive and close according to the action signal to provide the first open position state.

[0073] Specifically, after receiving a voltage signal from the control cabinet, the voltage relay coil is energized, generating an action signal. Upon receiving this action signal, the normally closed contact of the voltage relay opens, and the normally open contact closes. At this time, the normally closed contact simulates the closed position of the exhaust valve in the field, and the normally open contact simulates the open position. The first closed position and the first open position are digital signals. When the first closed position is a switch quantity 1 and the first open position is a switch quantity 0, it indicates that the simulated exhaust valve is in the closed position and is operating normally; when the first closed position is a switch quantity 0 and the first open position is a switch quantity 1, it indicates that the simulated exhaust valve is in the open position and is operating normally.

[0074] Furthermore, such as Figure 3As shown, in some embodiments, the fault simulation module 120 includes a first fault simulation unit 121 and a second fault simulation unit 122 connected to the input terminal of the control cabinet.

[0075] The position fault signal includes a second open position state and a second closed position state; the position fault signal includes a first position fault signal and a second position fault signal.

[0076] The first fault simulation unit 121 is used to trigger fault debugging action and generate a first position fault signal to simulate a fault in which both the second open position state and the second closed position state are output at a high level.

[0077] The second fault simulation unit 122 is used to trigger fault debugging actions and generate a second position fault signal to simulate a fault where both the second open position state and the second closed position state are low-level outputs.

[0078] In the first fault simulation unit 121, the unit that triggers the fault debugging action is the first triggering unit, and the unit that generates the first position fault signal is the first fault signal generating unit. In the second fault simulation unit 122, the unit that triggers the fault debugging action is the second triggering unit, and the unit that generates the second position fault signal is the second fault signal generating unit.

[0079] Optionally, the fault simulation module 120 and the simulated exhaust valve module 110 can be set up separately, or the fault simulation module 120 and the simulated exhaust valve module 110 can be set up in conjunction. That is, the position fault signal of the fault simulation module 120 can be generated by the signal generating unit 112 of the simulated exhaust valve module 110, and the first fault signal generating unit, the second fault signal generating unit, and the signal generating unit 112 share a single signal generating device; or, the first fault signal generating unit, the second fault signal generating unit, and the signal generating unit 112 can each be set up with a separate signal generating device. Optionally, the signal generating device includes a voltage relay.

[0080] In the embodiments provided by the present invention, the first fault simulation unit 121 includes a first button; the first button includes a first contact and a second contact; the first end of the first contact is connected to the first end of the normally open contact, and the second end of the first contact is connected to the second end of the normally open contact; the first end of the second contact is connected between the first end of the normally closed contact and the input terminal of the control cabinet, and the second end of the second contact is connected between the second end of the normally closed contact and the second button.

[0081] In the embodiments provided by the present invention, the second fault simulation unit 122 includes a second button; the second button includes a third contact and a fourth contact; one end of the third contact is connected to the input terminal of the control cabinet, and the other end is connected between the normally open contact and the first contact; one end of the fourth contact is connected to the input terminal of the control cabinet, and the other end is connected between the second end of the second contact and the second end of the normally closed contact.

[0082] In the embodiments provided by the present invention, the first fault signal generation unit of the first fault simulation unit 121, the second fault signal generation unit of the second fault simulation unit 122, and the signal generation unit 112 share a signal generation device, that is, the signal generation device is the normally closed contact and normally open contact of the voltage relay.

[0083] Specifically, when the first button is pressed, the simulated field exhaust valve simultaneously outputs both open and closed position faults; that is, the first fault simulation unit 121 generates a first position fault signal with both the second open position state as switch quantity 1 and the second closed position state as switch quantity 1. When the second button is pressed, the simulated field exhaust valve fails to output both open and closed position faults; that is, the second fault simulation unit 122 generates a second position fault signal with both the second open position state as switch quantity 0 and the second closed position state as switch quantity 0.

[0084] In the embodiments provided by the present invention, the signal module 130 includes: a signal light for receiving the action debugging result or fault debugging result output by the control cabinet, so as to indicate whether the logic processing of the control cabinet is normal.

[0085] In the embodiments provided by the present invention, the debugging device further includes a terminal block for quick connection between the control cabinet and the debugging device; the voltage relay also includes a 24V voltage relay, and the action debugging command includes a 24V voltage signal. In order to simulate the field exhaust valve as much as possible and match the output voltage of the control cabinet, a 24V voltage relay is selected as the simulated exhaust valve module 110, and the action debugging command issued by the control cabinet is a 24V voltage signal.

[0086] Optionally, the debugging device can be configured with multiple redundant columns. (See reference) Figure 2 In the embodiments provided by the present invention, the debugging device further includes a redundantly configured second simulated exhaust valve module 210 and a second fault simulation module 220. The unit composition and connection method of the redundant modules are the same as those of the simulated exhaust valve module 110 and the fault simulation module 120 described above.

[0087] like Figure 3 The diagram shown is a structural diagram of the commissioning system for the exhaust control cabinet of a nuclear power plant reactor top cover provided by the present invention. It includes the above-mentioned commissioning device for the exhaust control cabinet of a nuclear power plant reactor top cover, and also includes a control cabinet 140.

[0088] The control cabinet 140 is used to send action debugging commands, receive and display position signals or position fault signals, and perform logical processing on position signals or position fault signals to output the corresponding action debugging results or fault debugging results to the signal module 130.

[0089] The simulated exhaust valve module 110 and the fault simulation module 120 in the debugging device are connected to the input terminal of the control cabinet 140, and the signal module 130 is connected to the output terminal of the control cabinet 140.

[0090] Furthermore, the control cabinet 140 also includes a PLC logic control module. The PLC logic control module is used to perform logical processing on position signals to obtain signal processing results, and to perform logical processing on position fault signals to obtain fault debugging results.

[0091] Furthermore, the control cabinet 140 also includes a display module. The display module is used to acquire and display the first open position state and the first closed position state in the position signal, and to acquire and display the second open position state and the second closed position state in the position fault signal.

[0092] refer to Figure 1 , Figure 2 , Figure 3 The commissioning system for the exhaust control cabinet of the reactor top cover in a nuclear power plant provided by this invention is also used to implement the commissioning method for the exhaust control cabinet of the reactor top cover in a nuclear power plant provided by this invention. Specific embodiments are as follows:

[0093] Control cabinet 140 issues an action debugging command, which is a 24V voltage signal. Upon receiving this signal, the voltage relay is energized, causing the normally closed contact to open and the normally open contact to close, generating a position signal. Control cabinet 140 receives the open and closed position states from the position signal, performs logical processing, and outputs the action debugging result. Signal module 130 receives and displays this result. If signal module 130 displays "normal," it indicates that the logical processing result of control cabinet 140 for the normal position state of the field exhaust valve is correct. If signal module 130 displays "abnormal," it indicates that the logical processing result of control cabinet 140 for the normal position state of the field exhaust valve is incorrect, and the logic channels of the control cabinet need to be repaired and debugged.

[0094] Pressing the first button SB1 triggers the fault debugging action. Since the button changes the switching state of the voltage relay output, the voltage relay generates a first position fault signal, with both the open and closed positions displaying a switching quantity of 1. The control cabinet 140 receives the first position fault signal, performs logical processing, and outputs the fault debugging result. The signal module 130 receives and displays the fault debugging result. If the signal module 130 displays "normal," it indicates that the logical processing result of the control cabinet 140 on the fault position state of the field exhaust valve is incorrect; if the signal module 130 displays "abnormal," it indicates that the logical processing result of the control cabinet 140 on the fault position state of the field exhaust valve is correct.

[0095] Similarly, pressing the second button SB2 triggers the fault debugging action. At this time, because the button changes the switching state of the voltage relay output, the voltage relay generates a second position fault signal, resulting in an output fault where both the open and closed positions are both at a switching value of 0. After receiving the second position fault signal, the control cabinet 140 performs logical processing and outputs the fault debugging result. The signal module 130 receives and displays the fault debugging result. If the signal module 130 displays "normal," it indicates that the logical processing result of the control cabinet 140 on the fault position state of the field exhaust valve is incorrect; if the signal module 130 displays "abnormal," it indicates that the logical processing result of the control cabinet 140 on the fault position state of the field exhaust valve is correct.

[0096] By implementing the nuclear power plant reactor top cover exhaust control cabinet commissioning method, device and system of the present invention, the signals generated by the on-site exhaust valves can be simulated to realize the logic channel test of the pressure vessel top cover exhaust control cabinet. This can reduce the on-site disconnection and wiring, reduce the risk of control cabinet damage and poor logic test results caused by operational errors, and optimize the system availability period.
