Discussion and research on electric reliability evaluation of wind turbine

Abstract

With the rapid development of wind power in China, the installed capacity has leapt to the top of the world in a few short years, and is the fastest growing power source in addition to solar energy. However, power generation capacity and installed capacity of wind turbines in China are not in proportion to the world average; the unplanned outage coefficient of wind turbines in China is much higher than the world level. Therefore, it is urgent to carry out research on the reliability of generator sets. This study analyzes and summarizes the general conditions and problems of China’s generating units, the theoretical basis of reliability evaluation of wind turbines, wind power reliability evaluation procedures, and cases, and proposes major ways to improve the reliability of wind turbines and wind farms for the majority of the Wind power industry professional and technical personnel learn from and exchange.
