A method and system is disclosed for generating a steam turbine overspeed control system fault alert. The method can include providing an overspeed control system with a control valve configured and located to adjust a speed of the steam turbine, the control valve having a control position. The method can also include monitoring the control position of the control valve and detecting a deloading event. Upon detection of a deloading event, a control system fault alert is generated when the control valve does not achieve a predefined control position within a predefined time from the deloading event.
