摘要

由于串联补偿电容器串联在线路中

存在和负载中的电机产生谐振的问题

为了解决这个问题

设计的串补度往往不能过高

否则影响补偿效果。本文提出了一种适合10 kV配电线路的串、并联混合电容器补偿技术。详细研究了其基本工作原理、推导出了补偿电压和补偿无功功率的公式、分析了串联和并练补偿电容器的相对位置对补偿效果的影响;提出了并联和串联补偿容量的确定策略;通过对一回实际10 kV线路的补偿设计和计算机仿真计算

进一步阐述了容量设计策略

并验证了理论分析的正确性。最后介绍了应用该技术的一个实际工程案例。

Abstract

The resonance issue is generated with the motor in the load because the series compensation capacitor is in series in the line. For solving the problem

the design series compensation degree shall not too high

otherwise the compensation effect will be affected. In this paper

a kind of series and parallel mixed capacitor compensation technology which is suitable for 10 kV power distribution line is proposed.Its basic operating principle is studied in detail

the formula of compensation voltage and compensation reactive power is derived and the influence of relative position of series and parallel compensation capacitor on the compensation result is analyzed. The strategy on deterring the parallel and series compensation capacity is proposed and the capacity design strategy is described further by way of compensation design and computer simulation calculation of one circuit real 10 kV line and the correctness of the theoretical analysis is verified.Finally

one real engineering case with the technology is introduced.
