The invention relates to the nuclear power station digital control technology field and provides a test device of a main processing unit of a nuclear power station protection system and a test method. The test device comprises a communication interface; a test loading unit used for loading a preset test case; a test performing unit used for performing the test case, before the test case is performed, a value of the main processing unit of the nuclear power station protection system is read through the communication interface according to test conditions corresponding to the test case, whether the value of the main processing unit satisfies a value required by the test conditions is determined, when the test conditions are satisfied, an operation result of the main processing unit of the nuclear power station protection system is transmitted through the communication interface to the test performing unit of the test device; and a test result output unit, a test result is automatically generated according to the result of the test performing unit. The test device is advantaged in that T2 test in the nuclear power station protection system can be conveniently and rapidly accomplished.
Description
technical field [0001] The invention relates to the technical field of nuclear power plant digital control, in particular to a test device and method for a main processing unit in a nuclear power plant protection system. Background technique [0002] With the wide application of digital technology in various industries and the improvement of reliability, the current protection system of nuclear power plants also adopts digital technology, and the analog system used in earlier nuclear power plants is gradually being upgraded to a digital system; due to the particularity of nuclear power, There are higher requirements for the normal and stable operation of the digital control system, so it is very important to regularly test and maintain the digital control system. Taking the T2 test as an example, in the era of analog systems, in order to complete the T2 test, a separate test device needs to be designed, and a separate location is required to store the test device and cables ...
