摘要
针对矿井提升机对电网造成无功冲击和高次谐波污染等问题,文章以焦煤集团某矿提升机负荷的特性为例提出了一种矿井提升机TSC型动态无功补偿方案,分析了矿井提升机负荷对电网的影响及产生的谐波电流,详细介绍了该方案的设计实现。仿真结果表明,该TSC型动态无功补偿方案基本上能满足动态补偿的要求,可提高网侧的功率因数并减少谐波向高压电网的输入,减小谐波电压和谐波电流畸变率。
Aiming at the problems of impact of reactive power and high-order harmonic wave pollution caused by mine hoist to power grid, the paper proposed a scheme of TSC type dynamic reactive power compensation of mine hoist taking characteristics of hoist load of one coal mine of Jiaozuo coal mine group as sample. It analyzed influence of mine hoist load on power grid and harmonic current produced by mine hoist load, and introduced design and implementation of the scheme in details. The simulation result showed that the scheme of TSC type dynamic reactive power compensation can satisfy the requests of dynamic compensation basically, and can enhance power factor of net side and reduce input of harmonic wave to high-voltage power grid as well as reduce distortion rate of harmonic voltage and harmonic current.
