With the progress of science and technology,the level of industrial development in China has also been greatly improved,especially the quality and demand for electricity have been increasing.Turbine generator is one of the important equipment in electric power system,the fault of any component in the use process will directly affect the entire steam turbine power generation system.Among such faults,rotor shorted turns and grounding short circuit are two types of common faults,and due to insufficient detection and maintenance treatment,single-point small faults often develop to multiple-point major faults.This paper mainly analyzes the detection methods and causes of electrical faults of turbine generator rotor,and puts forward scientific and reasonable maintenance methods and preventive measures.
