SVG无功补偿技术在煤矿电网中的应用研究

Application of SVG Reactive Power Compensation Techniques in Coal Mines Power Grid

随着煤矿中电力电子驱动装置及大型电机的普遍应用,大量的谐波分量和无功冲击会引起供电系统电网产生较大波动,降低电机功率因数。提出在煤矿6 k V电网中使用SVG静止型无功补偿装置,通过对其原理的分析,针对实际工程设计出控制算法和电路方案。实际效果表明SVG无功补偿装置有效地改善了煤矿电网的供电质量,抑制谐波产生,提高功率因数,使得煤矿生产供电稳定而可靠。

With the widespread application of coal in power electronic motor drives and large, a large number of harmonics and reactive power supply system impact will cause greater volatility, reduce motor power factor. Proposes the use of SVG in 6 kV mine in static reactive power compensation device, through the analysis of its principles, the actual engineering design of control algorithms, and circuit solutions. Actual results indicate SVG reactive power compensation device effectively improve the power supply situation in the coal mine, suppress harmonics and improve the power factor, making a stable and reliable supply of coal production.
