摘要
单元串联多电平(Cell Series Multi-Level：CSML)PWM技术是一种成熟的多重化变频技术。文章在比较了几种市场化的高压变频技术的基础上,介绍了CSML PWM技术的原理与特点,并以山东黄台火力发电厂#8炉引风机节能改造项目的经济性得出,采用CSML方式的高压变频器是目前火力发电厂厂用高压电动机节能改造项目的高性价比解决方案。
CSML （Cell Series Multi-Level） PWM technology is a mature multiplex conversion technique. Its principle and characters are analyzed in this paper, on the basis of comparing several mature high-voltage conversion topologies. The economical efficiency is analyzed with example of No.8 boiler＇s suction motors＇ energy conservation item in Huangtai Power Plant.lt is concluded that the solution with a large ratio of performance to rate for energy conservation of high-voltage motors in power plant is to choose CSML PWM high-voltage converters.
