In light of the situation that the nationwide interconnection of power networks in China in the coming years will take shape, it is imperative to emphasize the importance of setting up rational power network configuration. Combined with the characteristics of regional power networks in China, problems in network planning that need to be solved are put forward in this paper, such as, the access of power plants to grid by layers and zones, the share of external power in the load of local network, the power network configuration study in-depth in planning and design stage, and enforcement of receiving-end power network trunk etc. The background of these problems and their countermeasures are also analyzed in the paper.%针对我国未来形成全国互联电网的局面,强调建立合理电网结构的重要性.结合我国区域电网的特点,提出电网规划中需要解决的问题,如电厂的分层分区接入,外来电力占本网负荷比例,规划设计阶段对电网结构的研究深度,加强受端网架等,分析这些问题的背景和解决对策.
