摘要(Abstract)：
为适应电力负荷密度的不断增长 ,在负荷密度较高的区域内选择更大的变电站建设规模是必要合理的。针对当前电网面临的短路电流超限问题 ,优化电网结构的措施应包括在负荷较密集区域提高变电站建设规模 ,使各级线路、变电容量相互协调匹配 ,合理选择变电站电气主接线和严格限制500kV出线回路数。
To meet the requirement of increasing high denisity of power load, it is necessary and reasonable to select larger substation capacity scale. To resolve the short_circuit current of the electric network surpassing the limitation being faced with at present, the measures of optimizing the electric network structure should include raising substation capacity scale and coordinating it with the transmission lines and other substations, selecting suitable substation bus scheme, and restricting the substation 500 kV lines.
