摘要:
为了保护柔直输电系统的全控性电力电子元件,在柔性直流换流站的桥臂和换流阀侧会安装避雷器。为了评估避雷器的运行状态,在每一台避雷器上安装了泄漏电流在线监测装置。依托厦门柔直输电工程,统计研究了两个换流站的各个位置避雷器从2016年到2018年5月的泄漏电流监测数据,发现了泄漏电流随着负荷增加而增加的现象。在此基础上对监测表计进行了强谐波下的检测,发现针对交流避雷器设计的监测表计用在柔直避雷器泄漏电流的在线监测上,存在较大测量误差,此外,柔直站运行时产生的大量谐波也是影响其电流监测数据的主要原因。
Abstract:
In order to protect the IGBT of VSC-HVDC system, some lightning arresters are installed in bridge and commutation valve. In order to evaluate the running state of lighting arresters, online leakage current monitoring device are installed on each arrester. It is studied statistically that the leakage current monitoring data of lightning arresters at different locations of two converter stations from 2016 to May 2018 and it is found that the leakage current increases with the increase of load based on VSC-HVDC project in Xiamen. The monitoring meter is tested under strong harmonics under these circumstances and it is found that there is a large measurement deviation in the monitoring meter designed especially for AC arrester which is used for online monitoring of the leakage current of VSC-HVDC arrester instead of AC arrester. In addition, a large number of harmonics generated by flexible station operation are also the main reason affecting the leakage current monitoring data.
