Abstract

The invention discloses a reactor protection system channel response time intelligent testing system and method. The system comprises an integrated controller, a first channel selector, a second channel selector, and a high speed record card. The integrated controller is used for outputting a group simulation signal and a channel selection control signal and is connected with a nuclear power plant digital control system. The first channel selector is used for receiving the group simulation signal and selecting one signal as a protection input record sample according to the channel selection control signal. The second channel selector is used for receiving the channel selection control signal and selecting one signal as a protection output record sample according to the channel selection control signal. The high speed record card is used for recording change time difference data of the protection input record sample and the protection output record sample. The integrated controller carries out calculation according to the change time difference data to obtain reactor protection system channel response time, so that automation of the whole testing process and automation of data processing can be achieved, and lots of time and cable consumables are saved.

Description

technical field [0001] The invention relates to the field of equipment response time testing, in particular to a reactor protection system channel response time test system, and more specifically, to an intelligent test system and method for reactor protection system channel response time. Background technique [0002] Reactor protection channel response time is a key technical index to judge the effectiveness and timeliness of reactor protection triggering. Nuclear power plant safety guidelines have strict requirements on the response time of various protections. For the response time test of the protection channel, high-speed recording cards and signal simulation equipment are generally used at home and abroad, and it is completed by continuously manually replacing the wiring, manually replacing the simulation signal and the protection signal. However, since various protection signals need to be triggered multiple times, it brings great difficulties to field equipment isol...
