The Design And Realization Of Nuclear Power Plant DCS Test Instrument

The nuclear power plant Digital Control System (hereafter as "DCS")is the critical device of the nuclear power plant,it is will maintain power plant security, maneuverability and reliability, to assuring power plant carry out the protection funcion in all running and emergency situation. The DCS process is complex,the response time is very short(normally at millisecond),the test of DCS is very difficult.This subject research and simulate the requirements of power plant process, acquire the test requirements. According to the requirements, acquire the design requirements of the automatic test, combine the standard,.development the structure,software,hardware,finally, realize a automatic test equipment by the Virtual Instrumentrtual instrument, which can be carried out test automatic with high precision.The Virtual Instrumentrtual automatic test equipment has characteristics of versatility andflexibility.Application development is really convenient. This equipment can carry out the critical funcion and performance automatically.At present,this equipment have been used to the test activity, it improves the test coverage, accuracy andefficiency. So it has a good practical value.
