摘要
大功率风机和泵采用调速传动有巨大效益,现有的调速方法有两大类:定子侧中压直接变频和转子侧串调,文中介绍了6种调速方法,谈了个人看法,重点在如何改进串调性能。
A lot of benefits will be achieved if variable speed drives are employed for high Power fans and pumps. There are two sets of adjusting speed methods: stator side medium voltage variable frequency one and rotor side cascade one. Six kinds of drive systems are introduced in this paper and personal viewpoints are mentioned. The focus is how to improve performance of the cascade one.
