摘要
绕线异步电动机因采用传统串级调速控制,受调速范围、功率因数、谐波污染等问题影响,其推广应用受到限制,故提出采用双PWM整流器的双馈串级调速控制方案。给出了整流器的控制策略以提高调速系统的可控性和控制精度。仿真和模拟实验验证了所提方案和控制策略的有效性。
Application of the traditional Scherbius variable-speed control of winding induction asynchronous motor is restricted by its speed-range,power factor and harmonic pollution,etc..The scheme of doubly fed Scherbius system with double PWM rectifier is proposed,and the control strategies of the supply-side PWM and the rotor-connected converter are given respectively.All conclusions are supported by simulation and practical experiments.
