METHOD FOR TESTING PROTECTION AGAINST EXTRA MINIMUM ROTATION SPEED OF A SINGLE GAS AND STEAM TURBINE INSTALLATION

摘要

A method for testing an overspeed protection mechanism of a single-shaft combined-cycle plant that includes, during testing, an electrical load is first connected to the generator and the load is disconnected and a trigger threshold value can be achieved at a test moment in time, thereby triggering the overspeed protection mechanism.
