摘要
随着生产的发展,装置的扩建、设备的增加,用电负荷日趋增大,与此同时线路损耗、变压器损耗也在不断的增加,从而导致功率因数也在下降。介绍了无功补偿节能改造原因及方式的选择,并进行了无功补偿方案的经济分析。
The power load is added gradually along with expanding the production devices,meanwhile the line and transformer loss increase continually which bring about the power factor decreasing.The reformation reason and mode selection are presented,and the economic analysis for compensation scheme are also given.
