韶山4改型电力机车功率因数补偿的研究

Study on Power Factor Compensation of Shaoshan 4-modified Electric Locomotive

本文将电力机车现代化的功率因数补偿手段和使用特点作为基础,分析了韶山4改型电力机车谐波对电流的干扰以及功率因数较低两个问题。诠释了电气化铁道的功率因数补偿、谐波抑制主要方法及功率因数补偿和谐波抑制谐波的基本原理。设计和实现了韶山4改型电力机车功率因数补偿装置,通过对功率因数补偿装置的应用效果分析,提出了补偿装置的投切过程和原则,最终达到了对电力机车装置的保护及补偿目的。

Taking the compensation means and characteristics of the electric locomotive modern power factor as the basis, this paper analyzed interference to harmonic current brought by Shaoshan 4-modified electric locomotive and low power factor, interpreted the power factor compensation and harmonic suppression method of electrified railway and the fundamental principle, designed and implemented power factor compensation device of Shaoshan 4-modified electric locomotive, put forward the switching process and principles of compensation device through the application effect analysis of power factor compensation device, and eventually reached the protection and compensation purpose of electric locomotive device.
