研究了供电系统中SVG(Static Var Generator,静止无功发生器)无功补偿技术的具体应用.首先对SVG的原理进行了分析.其次以A煤矿项目为例,分析了该煤矿无功补偿情况及现状问题,提出选用SVG代替现有FC(Filter Compensation,谐波补偿)装置的方案,并详细地对SVG的监控系统及运行测试进行了分析.结果显示,SVG的应用可以提高煤矿电网功率因数、治理谐波、抑制电压波动,达到节能降耗和改善电能质量的效果.最后展望了SVG无功补偿技术的前景,并提出了相关的建议.
Specific Application of SVG Reactive Power Compensation Technology in Coal Mine Power Supply Systems
This paper investigated the specific application of SVG(Static Var Generator)reactive power compensation technology in power supply systems.Firstly,it analyzed the principle of SVG.Secondly,taking the project in A Coal Mine as an example,it analyzed the situation and current problems of reactive power compensation in the coal mine,proposed a plan to replace the existing FC(Filter Compensation)device with SVG,and conducted a detailed analysis of the SVG monitoring system and operational testing.The results show that the application of SVG can improve the power factor of coal mine power grid,control harmonics,suppress voltage fluctuations,achieve energy-saving and consumption reduction,and improve power quality.Finally,it looked forward to the prospects of SVG reactive power compensation technology and put forward relevant suggestions.
