摘要
矿井采用的可控整流型大功率直流提升机是一种典型的冲击性负荷,它的运行给电网带来了大量的无功冲击,致使电网电压波动,严重威胁供电系统的安全运行。因此,对提升机的供电系统进行动态无功补偿是十分必要的,但是目前常用的动态无功补偿装置(如TCR、TSC)都有着各自的缺陷。采用了新型的MCR动态无功补偿技术,通过建立Simulink系统补偿模型,验证了其动态补偿的性能,也凸显了其技术上的优势。
The controllable rectifier high-frequency DC hoister adopted by coal mine is a typical impulsive load, its motion brings a great deal of reactive power impact to power system, which makes wave motion to voltage, and seriously threatens the safe run-time of power supply system. So it is necessary to do dynamic reactive power compensation to the power system of hoister. But the var compensation devices mostly used nowaday（for example：TCR ,TSC）all have their shortcomings.Adopted the new MCR vat compensation device validates its capability to do dynamic reactive power compensation by building a simulation of compensation model, in this way ,it show the advantage of this technology.
