水泉选煤厂无功补偿的研究与实践

Study and Practise of Reactive Power Compensation in Shuiquan Cleaning Plant

结合水泉选煤厂用电系统的实际情况,分析了选煤厂用电系统功率因数低的原因,同时对比目前常用几种无功补偿设备的优缺点,采用一种新型的电压无功自动调节装置对水泉选煤厂一车间的用电系统进行高压无功集中补偿,在一车间无功补偿取得了良好的使用效果后,对选煤二车间的用电系统也进行了高压无功处支补偿改造,实现了高压电容器补偿的无人值守自动调节,符合国家对环保和节能的要求,取得了良好经济效益和社会效益。

Based on the situation of power supply system of Shuiquan cleaning plant, the article analyzes the causes of low power factor of the power supply system, comparing with reactive power compensation devices usually used, a newkind of pressure reactive automatic controlling device is recommended to perform high- voltage reactive intensive compensation for power supply system in No.1 Workshop of Shuiquan Cleaning Plant. With positive result in No.1 Workshop, similar transform is performed in No.2 Workshop. In t...
