| 摘 要： | 沿10 kV线路主变接下来的电力用户,依据无功补偿就地就近平衡原理,由安装在变压器0.4 kV侧的电容器组除对用电负荷无功进行补偿外,并通过过补偿方式对变压器励磁和漏磁无功进行补偿,使之线路流动无功最小化,降低了线路有功损耗。通过对无功补偿装置和运行方式的改变,降损节能效果较显著。经一年多时间运行,该无功补偿装置安全、可靠。

| Abstract: | Along the 10 kV line T for power users,on the basis of wattless power compensation in near baIanee principle, the capacitor group is installed on the 0. 4 kV side of the transformer for electric load wattless compensation, and also the compensation of transformer magnetizing and leakage by over compensation way, so that the line flows in wattless power minimization, which reduces the line active power loss. Based on the non reactive power compensation device and the change of operation mode, loss reduction and energy saving effect is remarkable. After one year＇ s running, the set up is safe and reliable. |
