Review Of Research On Fault Analysis Of Large-Scale Motor-Generator

Based on power balance and stability of power grid, pumped storage power station plays an important role in modern power system. Motor-generator is the main equipment of a pumped storage power station. The fault rate and operation reliability of motor-generator is directly related to safe and stable operation of the power station and even the power grid. This paper summaries different types of faults with several examples of fault treatment of large-scale motor-generators, and puts forward corresponding countermeasures and suggestions, which provides a good reference for similar fault prevention and diagnosis.
