Abstract
A gas turbine overspeed protection method includes: a power utilization load of a generator is acquired, and a rotating speed value of a gas turbine is acquired; whether the power utilization load suddenly decreases or disappears is judged, and if so, an eddy current retarder is controlled by a controller to simulate the power utilization load to provide a braking torque for the generator; or, whether the rotating speed value exceeds a set speed range is judged, and if so, the gas turbine is controlled by the controller to reduce fuel supply, and a discharge valve of a gas compressor is opened to discharge a high-pressure gas to reduce the power output and the rotating speed of the gas turbine.
