| 摘 要： | 随着电力系统的发展,大量的并联电容器组在配电网被用来提高电能质量,补偿系统无功。这些并联电容器组通常要求频繁操作。针对真空断路器投切并联电容器组产生的过电压和过电流,采用了阻尼装置来进行限制。文章对阻尼装置的参数进行了选取,并利用电磁暂态仿真程序进行了研究和现场实测。

| Abstract: | With the rapid development of power system,More and more shunt capacitor banks are installed in distribution power grid.They may be switched on and off frequently by vacuum circuit breaker during a typical day.Damping circuit is used to limit the over-voltage and over-current.The selection of damping circuit parameter is introduced.Compare between field test and calculation by EMTP is also presented in this paper. |
