PROBLEM TO BE SOLVED: To provide a method of testing an overspeed protection system for reducing a possibility of a trip.SOLUTION: This embodiment have a technical effect that overspeed protection systems of power plant machines (105, 145) which have at least one shaft (137) is automatically tested (200). In one embodiment, the overspeed protection systems can automatically be tested during the power plant machines (105, 145) are decelerated in speed from a no-load rated speed (FSNL). In another embodiment, the overspeed protection systems of the power plant machines (105, 145) can automatically be tested during the power plant machines are accelerated in speed to the FSNL. |
