摘要
煤矿井下供电网络中大量无功功率的循环运行,容易引起煤矿井下电网供电质量的显著下降,对机电设备造成损坏。文章简要介绍了煤矿井下供电系统的特点以及井下使用无功功率补偿的意义,重点分析了无功功率补偿技术原理和无功功率补偿方式的确定方法。
Cycling operation of large amount of reaction power in underground mine power supply system can easily lead to sharp drop of power supply quality and break the mechanical and electrical equipment.This paper briefly introduces characteristics of underground mine power supply system and the meanings of using reaction power compensation,it also focuses the analysis on the principle of reaction power compensation technology and determination method of reaction power compensation pattern.
