摘要
分析和探讨了补偿电网中性点位移电压异常的原因及危害,讨论了电网的网络结构、运行方式对中性点位移电压与自动跟踪消弧装置结构及调谐和运行方式对电网中性点位移电压(如电网不对称度、电网阻尼率等)的影响。基于电网运行、消弧装置结构和调谐运行方式诸方面的研究分别对补偿电网中性点位移电压采取了控制措施(如调整电网结构,加大消弧线圈补偿回路的阻尼率等)。
Reasons of abnormal displacement voltage of neutral points in compensation electric network and the harm are analyzed deeply. The effects of power structure and operation on the displacement of neutral points are discussed. Based on it, the effects of structure, tuning and operation manners of automatic tracing arc suppression device on the displacement of neutral points are discussed. The control measures of abnormal displacement voltage of neutral points in compensation electric network are introduced based on power networks operation, arc suppression device structure, tuning and operation manners.
