Abstract :
There is an AC/DC transmission system in Sichuan power grid include 1000kV UHVAC transmission and ±800 kV UHVDC transmission, after Jingsha river hydropower stations and their UHVDC transmission were finished. Power network structure of Sichuan power grid will be more complicated. According to the characteristic of Sichuan power grid, the control method of DC active power coordinated control is selected. And the influence of Sichuan power grid stability of ample flow period maximum method caused by DC active power coordinated control is analyzed. The result of research shows that the capability of Sichuan power grid against serious fault can be improved with DC active power coordinated control.
