摘要
以云广±800kV直流输电工程为背景,探讨直流输电线路工程通信保护设计中,求解电磁感应的等效短路电流的简便方法,所得到的结果能应用TXBH程序进行通信影响计算,并能方便地计算杆塔地电位。
Yunnan-Guangdong ±800 kV DC project is taken as an example,and a simple calculation method for equivalent short-circuit current in the communication protection design for DC power transmission lines is discussed.The results can be applied to calculate communication interference effects by using the TXBH program and determine the grounding voltage rise of DC power tower easily.
