The application provides a kind of nuclear power plant reactor protection system driver connection lockout test test method, comprising: when the first test enable signal TE1 of all control preferred module in the control preferred module cabinet to be tested = "1" and the second test enable signal TE2 = "1", after executing a test command, execute the next test command;The read-back information TA and TB of test port are used to read the test feedback state result of all control preferred module in the control preferred module cabinet to be tested;Judge whether the test feedback state result is consistent with the expected result;If not, directly terminate the test, and transmit the abnormal result to the man-machine interface device, so as to prompt the abnormal result on the man-machine interface of the man-machine interface device;If consistent, judge that the test " passes " and transmit the test " passes " result to the man-machine interface device.The application adopts the method of online testing to solve the human error risk caused by manual forced method in traditional control preferred module test.

The application relates to a channel precision, response time and protection setting value automatic testing device of a nuclear power plant reactor protection system based on a NASPIC platform, and particularly relates to a nuclear power plant reactor protection system testing device. Field instruments or sensors are simulated, signals are injected into a NASPIC platform safety level DCS system port, corresponding output signals of the safety level DCS system are collected, data of a safety level DCS engineer station are acquired, comparison or logical operation is carried out, and a corresponding test report is generated. The application realizes a reactor protection system regular test automatic testing technology based on the NASPIC platform, can greatly shorten a test time, improve work efficiency and reduce human errors.
