摘　　要：介绍了采用自并励磁系统的大型汽轮发电机组在电力系统中的优点和推广应用需注意的问题.根据目前国内外自并励励磁系统的应用情况,提出了在大型汽轮发电机组采用自并励励磁的可行性.重点探讨了在自并励励磁系统的运行方式下,提高机组强励能力指标所采用的具有高、低压桥式可控整流器的改进措施.This paper describes the merits and application problems for attention of self-shunt excitation used in large scale turbine-generator in power system. According to the application both at home and abroad,self-shunt excitation system for large thermal power generator is feasible. Importantly,improved measurements of high and low voltage controlled bridge rectirier adopted to enhance strong excitation ability index are discussed based on self-shunt excitation mode.
