Abstract

A method and system of testing an overspeed protection system of a turbomachine may include providing an overspeed protection system on a turbomachine having at least one shaft. The method may: determine whether a permissive or permissive(s) is satisfied; initiate an overspeed test; automatically adjusting the speed of a shaft; determining if the speed exceeds an overspeed trip value; and automatically disabling the automatic adjustment of the speed after the test is complete.
