摘要
针对华东电网福建与浙江加强联网工程500 kV线路同塔双回距离长、导线截面大等特点,对线路的感应电压和感应电流进行了专题计算,并对其影响因素(地线情况、线路换位方式、高抗中性点小电抗)进行了分析,为工程中设备正确选型提供依据。
The 500 kV enhanced Fujian-Zhejiang interconnection engineering, which transmits power through a twocircuit line on the same tower, has the features of long-distance and large conductor cross section. Based on these features, the induced voltage and current of the line are calculated, and their influences are analyzed, providing support for equipment selection in the engineering.
