摘要
采用电力系统等值程序 (NIMSCAN)软件 ,根据系统网络结构特点、典型运行方式和直流系统动态性能的要求 ,分别对华中—西北背靠背直流输电工程的两侧交流系统进行了等值简化 ,并采用BPA等软件比较等值前后的系统特性 ,提出了不同运行方式下研究直流系统动态性能的等值系统参数。
Respective equivalent models of the AC systems connecting to the back-to-back DC system between Central China grid and Northwest China grid are set up in order to do the dynamic performance study. The NIMSCAN program is used during the equivalent calculation of the two AC systems. The system characteristics before and after the equivalent treatment are compared by BPA software, and the parameters of equivalent system for study of dynamic performance of AC system in various operation conditions are proposed.
