摘要
为提高矿井供电稳定性、确保煤矿的安全生产,阐述了无功补偿在矿井供电系统中的意义.以山东某矿井为例,分析当前供电系统现状,根据静止无功发生器(Static Var Generator,SVG)原理,确定SVG控制方法与装置容量.结果表明,SVG就地无功补偿能够显著降低谐波含量,稳定电网电压.综合矿井情况,建议矿井结合供电系统制订无功补偿方案,满足设备运行需求.
Abstract
To improve the stability of mine power supply and ensure the safety of coal mine production,the signifi-cance of reactive power compensation in mine power supply system is expounded in this article.Taking a mine in Shandong Province as an example,the current status of the power supply system is analyzed.Based on the principle of the Static Var Generator(SVG),the SVG control method and device capacity are determined.The results indi-cate that SVG on-site reactive power compensation can significantly reduce harmonic content and stabilize grid voltage.Based on the overall situation of the mine,it is recommended that the mine develop a reactive power com-pensation plan in conjunction with the power supply system to meet the operational needs of the equipment.
