A new tuning method of arc suppression coil based on the increment of zero-sequence voltage amplitude
摘要
Abstract
In order to conveniently and simply measure the line-to-ground parameters in arc suppression coil grounding system, a new tuning method of arc suppression coil based on the increment of zero-sequence voltage amplitudes is proposed.In this method,the distribution network neutral point will be added the arc suppression coil and resistor , firstly measure the amplitude of the zero sequence voltage before incorporated resistance ;and measure the amplitude of the zero sequence voltage again after incorporated resistance , and then adjust the arc suppression coil inductance val-ue, further measure and record the amplitude of the zero sequence voltage .According to the recorded measured val-ues, it can be substituted into the equation to obtain the total capacitance and resistance to line -to-ground.Finally, build a model using Matlab simulation experiment and this method needn ’ t measure zero-sequence voltage phase .It has the advantages of simple operation , high accuracy and so on .It is very significant for the tuning of the arc sup-pression coil .关键词
