Study on the Feasibility of Oblique Wave Signal Injection Method in T1 Test-Bench Software

Reactor protection system is one of the most important systems to ensure the safe operation of nuclear power plant [1]. The T1 Test-bench software of Daya Bay nuclear power station consists of two parts: the main function module of software and the function module of periodic verification software. The former covers all the functions of the T1 cycle Test-bench of Daya Bay nuclear power station, and the latter is used to regularly inspect and calibrate the T1 Test-bench (generally, the cycle is one year). In this paper, the SIP channel test is carried out by physical slope test method, and the feasibility of this method is proved by simulation of case.
