A Study on the Electrical Characteristics of Key Bar in Large Turbine Generator

摘要

The turbine generator in power plant is responsible for the base load and operates for more than 20 years. Therefore it is important to ensure the reliability of the large turbine generator. The stator cores, which act as the main flux path of the generator, are supported by the key bar. In this paper, electrical characteristics of key bar are presented. Electrical characteristics of the key bar were predicted by the electromagnetic field analysis.
