摘要
交流电网是大区电网的主体；要加强其网络结构，组成坚强的网架。大区电网之间，应以直流互联，避免在我国幅员辽阔的土地上，出现大面积的交流大电网，潜伏着事故的互相影响。在远距离大容量输电问题上，直流输电将取代特高压交流输电。大区电网只要在引进直流输电主干线的同时，采取有力措施加强５００ｋＶ网络结构，采用双回５００ｋＶ线路，以及高自然功率线路等新技术，便不必要在５００ｋＶ主网之上再叠加更高一级交流电压。
The main part of regional networks is AC system and the network structure should be enhanced.The interconnections of regional networks will be DC mode to forbid an extended large AC network with possible extension of disturbances. DC will be more favorable than AC for long distance transmission.The regional network should take major effort to enhance 500kV network by adopting double circuit 500kV lines and higher transfer capacity transmission techniques while introducing DC.It is,therefore,not necessary to built an overlap higher AC voltage system on the present regional 500kV networks.
