在全国特高压电网规划及浙江电网规划的基础上，从浙江省电力电量预测和电力平衡的基本情况出发，分析特高压交直流站的供电区域、规划落点及其合理性，提出特高压浙中、宁东落点后的浙江主网优化调整方案，并对浙江特高压交直流混合系统的不同落点方案进行技术经济比较和分析。

On the basis of national UHV power grid planning and Zhejiang power grid planning, the power supply area, planning location and rationality of UHV AC/DC stations were analyzed, and an adjustment and optimization scheme for Zhejiang main grid by locating at Zhezhong and Ningdong was proposed, combined with the basic situation of power consumption forecast and power balance in Zhejiang Province. Finally, the technical and economic comparison and analysis were carried out on the different location schemes of Zhejiang UHV AC/DC hybrid systems.
