METHOD AND SYSTEM FOR TESTING OVERSPEED PROTECTION SYSTEM OF POWER PLANT

摘要

PROBLEM TO BE SOLVED: To provide a test method of an overspeed protection system which reduces the possibility of a trip.SOLUTION: The method and a system have the technical effect of automatically testing an overspeed protection system associated with a plurality of power plant machines of a power plant (100). The system may automatically test the overspeed protection system while at least one of the power plant machines is in the process of shutting down (300). The system may automatically test the overspeed protection system by adjusting the speed of a shaft (137) while at least one of the power plant machines (105, 160) operates under full-speed-no-load (FSNL).
