绕线式异步电机串级调速系统的设计
摘 要
串级调速是指绕线式电动机转子回路中串入可调节的附加电势来改变电动机的转差,达到调速的目的.大部分转差功率被串入的附加电势所吸收,再利用产生附加的装置,把吸收的转差功率返回电网或转换能量加以利用.
本文串级调速系统是双闭环控制系统,通过速度调节器和电流调节器等一系列环节输出触发角控制电压,再用单片机根据触发角的大小,来作相应的定时并发出触发脉冲,最后经过功率放大器等器件实现晶闸管的触发.
关键词：串级调速；转差率；双闭环；系统；触发
请不要再用软件或者谷歌翻译过来了，有能力的英语高手就帮我翻译一下！我等答案！

Wound cascade induction motor speed control system design
Abstract
Speed is the cascade-type motor rotor winding loop of string attached to the adjustable potential to change the motor to the poor,to achieve the purpose of speed.And deterioration of quality of power by the majority of string attached to the absorption potential,and then have the additional use of the device,the absorbing power of the poor to return to power grids or conversion to the use of energy.
In this paper,cascade speed regulation system is a double closed-loop control system,through the speed regulator and current regulator output to trigger a series of links in angle control voltage,and then single-chip microcomputer according to the size of the trigger angle to make the necessary trigger pulse from time to time and issued Finally,after the realization of power amplifiers and other devices to trigger the thyristor.
