串级调速系统中的变流技术

Converter Technology in Cascade Control System

高压大容量电机采用的串级调速是高效稳定的调速方法,其变流技术直接决定了串级调速的调速性能。文章对基于不同变流器的串级调速系统进行分析与研究,对完善串级调速系统的设计、促进变流技术的发展有一定意义。

Cascade control used in high-voltage and large-capacity winding motor speed adjustment is a high efficient and stable method, and the converter technology directly determines the speed adjusting performance of cascade control system. By studying on the cascade control systems consist of different converters, it has certain significance to improve the design of the cascade control system and to promote the development of the converter technology.
