| 摘 要： | 本文从中性点位移电压、三相电压不平衡度以及残流的有功分量、无功分量等方面,分析了阻尼率和脱谐度对补偿电网运行特性的影响,给出了合理配置阻尼率和脱谐度的公式,认为采用非线性电阻将增大残流的有功分量,不利于电弧的熄灭;在保证残流小于规程允许范围内的前提下,适当增大脱谐度,可改善三相电压不平衡度,有利于补偿电网的运行。

| Abstract: | The paper analyzes the influence of damp rate and out-of-resonance degree on running characteristics of power compensation network in aspects of neutral-point displacement voltage, unbalanced degree of three-phase voltage, power component and idle component of residual current, etc. The reasonable formula setting damp rate and out-of-resonance degree are given. It concluds that the adding power component of residual current caused by the application of nonlinear resistance will make against suppressing electric arc; and the proper accretion of out-of-resonance degree in the premise of residual current less then the permissible scope of regulations will improve the unbalanced degree of three-phase voltage, which makes for running of power compensation network. |
