摘　　要：永富直流“十三五”期间主要以送电广西电网为主,随着滇东南地区负荷的快速增长,永富直流需回送云南电网,满足新增负荷的用电需求,减轻云南电网500 kV南北交流断面和滇东南500 kV交流断面的输送潮流。本文对现状电网永富直流回送云南电网以及500 kV柳井输变电工程投产后永富直流回送云南电网的系统稳定性进行了仿真分析。仿真结果显示,现状电网不能完全满足永富直流回送云南电网的运行要求,500 kV柳井输变电工程投产后永富直流具备回送云南电网的条件。During the 13th Five-Year Plan period,Yongfu HVDC mainly transmission power to Guangxi grid.With the rapid growth of load in Southeast Yunnan,Yongfu HVDC needs to transmission power to Yunnan grid to meet the demand of new load and reduce the transmission tide of 500 kV north-south section of Yunnan grid and 500 kV AC section of Southeast Yunnan.This paper presents a simulation analysis of the system stability of Yongfu HVDC transmission power to Yunnan of the current grid and the grid after the commissioning of the 500 kV Liujing transmission project.The simulation results show that the current grid can not fully meet the operational requirements for the power transmission of Yongfu HVDC to the Yunnan grid,while it will be available after the commissioning of 500 kV Liujing transmission project.
