| Abstract: | The idea of coordinated control for the modulation of multi-HVDC transmission line systems in the southern power grid was put forward after analyzing the function of modulation control in HVDC systems for improving AC system stability. Through practical calculation and analysis, it is verified that the coordinated control of multi-HVDC transmission line systems is very important for improving AC system stability in the southern power grid. The preliminary scheme for the coordinated control in the southern power grid are discussed and presented. |
