Abstract:
1. A method of determining when a test of an overspeed protection system of a powerplant machine is recommended, the method comprising: providing a powerplant machine comprising a shaft and an operational control system, wherein the operational control system is configured for operating the powerplant machine and comprises an overspeed protection system configured for detecting an overspeed event associated with the shaft; providing a condition based algorithm configured for determining when a test of the overspeed protection system is recommended, wherein the condition based algorithm is integrated with the operational control system, and performs the steps of: a) monitoring a component of the powerplant machine, wherein the component is associated with the overspeed protection system; b) determining whether an interval is met; c) determining whether an operational event associated with the component has occurred; and d) adjusting the interval based on the operational event; wherein the condition based algorithm determines when the frequency of testing the overspeed protection system can be decreased.
