摘　　要：发电机组中性点采用消弧装置补偿方式时,中性点电压过高会严重影响系统的安全稳定运行。依据测量结果,分析了发电机三次谐波电压和传递电压对中性点电压的影响,为分析和判断发电机组中性点电压短暂异常升高的原因提供参考。When the arc suppression device is adopted in compensation for the neutral point of generator u- nits, neutral-point overvoltage can seriously affect the safe and stable operation of the system. Through the analysis of the impact of third harmonic voltage of generator and transfer voltage on the neutral point based on the measurement result, this paper can serve as a reference for determining and analyzing the reasons for abnormal short-time voltage rise of neutral points of generator units.
