The #7 and #8 steam turbine generators of Taizhou Power Plant are 330MW generator sets jointly produced by Beijing Heavy Electric Machinery Factory and Alstom (GEC--ALSTHOM), France, and are equipped with TKJ91--35 rotary brushless working exciters. They were put into operation on February 1, 1997 (#7) and December 23, 1997 (#8), respectively. By August 2005, they had undergone two major overhauls and six medium (minor) overhauls. During the major, medium and minor overhauls, the exciter pole windings were frequently burned. After years of exploration and practice, Taizhou Power Plant has made partial improvements to the air duct of the exciter, and achieved good results in actual operation.
