高频过电压抑制导线抑制VFTO的试验研究
|
摘要
为验证高频过电压抑制导线(以下简称抑制导线)对VFTO抑制效果,在某550 kV GIS试验平台上开展了VFTO抑制验证试验。为开展试验,依据IEC 62271?102—2013标准对试验平台的尺寸进行了优化设计。依据GIS的工作工况,设计了加交流、直流、隔离开关分闸、合闸等试验条件。从VFTO的幅值、持续时间、击穿次数和频率成分方面对安装抑制导线前后的试验结果进行了总结分析。试验结果表明:VFTO最高幅值可从安装前2.42p.u.下降为1.49p.u.;幅值抑制比最大可达52.94%,最小也有22.22%;安装抑制导线后,全波击穿次数可从13次减少到5次,持续时间从7个工频周波减少到2.5个工频周波;同时试验结果揭示抑制导线对VFTO的高频成分抑制效果明显。上述结果表明:高频过电压抑制导线法对VFTO具有很好的抑制效果,是一种极具工程应用前景的方法。
In order to verify the VFTO suppression effect of the restraining busbar,the VFTO suppression verification test was carried out on a 550 kV GIS test platform.In order to carry out the test,the dimensions of the test platform were optimized according to the IEC 62271-102—2013 standard.According to the working conditions of GIS,the test conditions of AC,DC,disconnector opening and closing are designed.From the aspect of VFTO,the duration,the number of breakdowns and the frequency components,the test results before and after the installation of the restraining busbar are summarized and analyzed.The test results show that the maximum amplitude of VFTO can be reduced from 2.42 p.u.to 1.49 p.u.before installation;the amplitude suppression ratio can reach up to 52.94%,and the minimum is also 22.22%;after installing the restraining busbar,the number of full-wave breakdown can be reduced from 13 times to 5 times,the duration is reduced from 7 power frequency cycles to 2.5 power frequency cycles;at the same time,the test results reveale that the restraining busbar has a significant effect on the high frequency component suppression of VFTO.The verification test shows that the restraining busbar has a good suppression effect on VFTO,and it is a method with great engineering application prospects.
