摘要
全电流补偿消弧线圈可有效解决接地故障残余电流中阻性与谐波电流成分的补偿问题,同时抑制电弧接地过电压,保证配电网供电的安全性和可靠性,因此具有广阔的应用前景。基于全电流补偿消弧线圈的原理、结构及研究现状,对全电流补偿消弧线圈研究存在的不足之处和利用其进行接地残流补偿时存在的技术问题进行总结,指出将零序电压作为检测和分析对象对残流补偿十分有利。最后,给出全电流补偿消弧线圈的控制思路,阐述了对其进行增容改造的必要性。
Full current compensation arc suppression coil can solve the compensation problem of resistive current and harmonic current components in residual current, also can suppress the arc-earthing over-voltage effectively, and ensure power supply security and reliability in distribution network, so it has a wide application prospect. Based on the principle, structure and research status of full current compensation arc suppression coil, the imperfections on full current compensation arc suppression coil research and the technology questions on residual current compensation are summarized. It points out that zero sequence voltage is regarded as a measure and analysis object is advantageous to residual current compensation. The control strategies of full current compensation arc suppression coil are put forward and the necessity of capacity increasing transformation iselaborated.
