32、trol/译文：现代交流调速系统的类型现代交流调速系统分为交流电动机、电力电子功率变换器、***和***四大部分组成。根据被控对象的交流电动机的种类不同，现代交流调速系统可分异步电机调速系统和同步电动机调速系统，在这里主要介绍异步电机调速系统。1/1异步电动机调速系统的基本类型由异步电动机工作原理可知，从定子传入的电磁功率Mp可分两部分/一部分mp=(1-s)Mp是拖动负载的有效功率；另一部分是转差功率sp=sMp与转差率s成正比。转差功率如何处理、是消耗还是回馈给电网，可衡量异步电机调速系统的效率高低。因此按转差功率处理方式的不同可把现代异步电机调速系统分为三类。(1)转差功率消耗型调速系统全部转差功率都转换成热量的形式消耗掉。晶闸管调压调速属于这一类。在异步电机调速系统中，这类系统的效率最低，是以增加转差功率的消耗为代价来换取转速的降低。(2)转差功率回馈型调速系统转差功率一小部分消耗掉，大部分则通过变流装置回馈给电网。转速越低，回馈的功率越多。绕线式异步电机串级调速和双馈调速属于这一类。(3)转差功率不变型调速系统转差功率中转子铜损部分的消耗是不可避免的，但在这类系统中，无论转速高低，转差功率的消耗基本不变，因此效率很高。变频调速属于此类。目前在交流调速系统中，变频调速应用最多、最广泛，可以构成高动态性能的交流调速系统，取代直流调速。l/2现代交流调速系统的发展趋势和动向
