Static self-excitation system has been more and more widely used for large turbogenerator units in China and achieved very good results in recent years. However, new problems have arisen along with the development of high-power thyristor technology, etc. In view of the actual operating condition of SEE900/5000 SCR static excitation system imported from Siemens, Germany, some technical renovations were carried out.
