摘　　要：为充分发挥西北地区的资源优势 ,加快西部大开发步伐 ,实现西电东送和在更大范围内满足资源优化配置的需要 ,西北电网现有的 330 k V网架不能满足水火电系统补偿调节的要求 ,迫切需要发展高一级电压等级。通过技术经济分析 ,认为西北电网在 330 k V以上采用 75 0 k V电压有利于网络结构的简化 。In order to bring resources superiority of Northwest China into full play, to speed up the great development of Northwest China, to implement the transmission of electric power from West China to East China and to meet the need of optimize configuration of resources in a larger scope,the existing 330kV power network in Northwest Power Grid can not meet the requirements of compensation regulation between the thermal and hydroelectric power generation,so that it is imminency to configure a higher voltage grade.Through the technical and economical analysis,it is considered that in favor of the simplification of power network to choose 750kV as the higher voltage grade above the 330kV is reasonable.
