摘要
大中型泵站工程电气设计中经常涉及到电动机启动、无功补偿的问题。通过多年的工程实践,对电动机常用的直接启动、变频器启动、自耦变压器启动、电抗器启动、变压器抽头启动、热变电阻启动、磁控电抗器启动及开关变压器启动等方式及第1、2、3代无功补偿装置的选择进行了技术经济方面的分析比较,提出了一些个人观点,供同行探讨。
The problems of electromotor starting and reactive compensation are often involved in electrical design of large and medium-scaled pumping station.The author makes a technical and economic analysis and comparison from the selection of electromotor direct start,converter start,compensator start,reactor start,transformer tapping start,thermistor start,magnetron reactor start,switch transformer start,and the first,second and third generations of reactive compensation installation,and put forward his own opinions in combination with years ofengineering practical experience.
