8月29日,云南电网与南方电网主网鲁西背靠背直流异步联网工程柔性直流单元建成并投运。据称,该工程为世界电压等级最高、容量最大的柔性直流输电工程。该工程在世界上首次采用大容量柔性直流与常规直流组合模式,将云南电网与南方电网主网相连的3条500kV交流线路通过交流变直流、再从直流变交流,实现云南电网与南方电网主网全部异步联
August 29, Yunnan Power Grid and Southern Power Grid main network Luxi back to back DC asynchronous network engineering flexible DC unit built and put into operation. Allegedly, the project is the world’s highest voltage level, the largest capacity of flexible DC transmission project. The project in the world for the first time using large capacity flexible DC and conventional DC combination mode, the Yunnan Power Grid and China Southern Power Grid connected to the three 500kV AC lines through the exchange of DC, then change from DC to AC, Yunnan Power Grid and the main power to achieve the main All asynchronous network
