Embodiment Construction
[0018] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0019] Such as figure 1 Shown is an embodiment of the nuclear power plant reactor protection system test simulation system of the present invention, including an actuator driver 11, a simulated normally closed drive circuit 12, a test bypass circuit 13, a test result display circuit 14, and a power supply 15. The power supply 15 supplies power to the actuator driver 11 , the analog normally closed drive circuit 12 , the test bypass circuit 13 and the test result display circuit 14 . In particular, the power supply 15 supplies power to the actuator driver 11 through the analog normally closed drive circuit 12, thereby keeping the actuator driver 11 in a power supply state. It can be understood that the actuator driver 1...

A disclosed test simulation system for a reactor protection system of a nuclear power station comprises an executing-mechanism driver, a simulation normal-close driving circuit, a test bypass circuit, a test-result display circuit, and a power supply for supplying electricity for the simulation normal-close driving circuit, the test bypass circuit and the test-result display circuit; the power supply supplies electricity for the executing-mechanism driver through the simulation normal-close driving circuit; the test bypass circuit comprises a test switch, and by triggering the test switch, power supplying for the executing-mechanism driver through the simulation normal-close driving circuit is switched off; and the power supply supplies electricity for an executing-mechanism driving relay through the test bypass circuit, and supplies electricity for the test-result display circuit for displaying the power-loss state of the simulation normal-close driving circuit. The system helps to simulate various failures of on-site equipment, further helps to solve the problems of off-line simulation on on-site failure and culturing of test personnel, and has the advantages of safety and reliability.
Description
technical field [0001] The invention relates to the field of nuclear power plants, in particular to a test simulation system which can be used for the T3 test of the reactor protection system of the nuclear power plant. Background technique [0002] The function of the reactor protection system is mainly to protect the integrity of the three major nuclear safety barriers (fuel cladding, primary circuit pressure boundary and containment). Shut down and start special safety facilities. [0003] For example, the RPR system of the Daya Bay Nuclear Power Plant is a nuclear reactor protection system, which is based on changes in the operating parameters of the power plant, through its logic to control the emergency shutdown of the reactor and the action of safety facilities, so as to prevent the state of the reactor from exceeding the specified safety limit or reduce the consequences caused by exceeding the safety limit. . Among them, the purpose of the T3 test is to verify the ...
