无功功率补偿在供配电系统设计中的应用

无功补偿能减少线路的损耗、减小导线截面积和变压器容量、减少线路压降。无功补偿的方式有变电所集中补偿、用电负荷就地补偿、配电线路的分散补偿等。无功补偿应注意的问题有防止产生自励、谐波问题、无功倒送问题、电压调节方式的补偿给设备带来的问题等。无功补偿的发展方向有电力有源滤波器、统一潮流控制器这说明了无功补偿在企业供配电系统设计中的重要应用。

Application of Reactive Power Compensation in the Design of Distribution System

Reactive power compensation can reduce the losses of each line, the cross-sectional area, transformer capacity and the line pressure drop as well. The modes of reactive power coition include centralized compensation in substation, on-site compensation in load, distributed compensation of lines and so on. For reactive power compensation, attention should be paid to the prevention of such problems as self-encouragement, reactive current injection and compensation of voltage regulator impacting on the operation of equipment. There are active power filter and unified power flow controller in the development of reactive power compensation. It shows that reactive power compensation is very important in the design of distribution system for enterprises.
