| 摘 要： | 针对换流站滤波器电容器出现漏油与爆炸的现象,结合背靠背换流站工程,运用ATP软件,分析换流站220kV侧交流滤波器关合时的涌流特征,计算不同类型滤波器关合时的涌流。结果显示:对于SC型滤波器,使用相控关合技术可将其关合的涌流倍数限制在标准规定的范围内;而对于HP12/24和HP3型滤波器,其涌流值较小,可不采用相角控制技术。考虑到断路器操作时的动作时间分散性,为将合闸涌流倍数限制在标准规定的20倍以下,对不同绝缘强度下降率(rate of decrease of dielectric strength,RDDS)的断路器进行研究,得到了RDDS与断路器合闸时间分散性对滤波器断路器相控关合初相角的影响,为背靠背换流站滤波器组相控关合断路器的选取提供了依据。

| Abstract: | To eliminate the leakage and explosion of capacitors for filters of converter station,based on back-to- back converter station project and by use of ATP software,the feature of inrush current during the switching of AC filter banks at 220 kV side of converter station is analyzed,and inrush currents during the switching of different types of filter banks are calculated. Calculation results show that for SC type of filter the multiple of its inrush current can be restricted to the range specified in the stand... |
