Research on Control Strategy of 800 kV Grid-forming Converter Station
The converter station is one of the important components of the new power system with high proportion of power electronic equipment. The grid-forming converter station has strong ability of frequency support and voltage support,this paper deduced the mathematical model of the converter station,and then deduced the control strategy of the converter station. In order to increase the frequency support and voltage support capability of the converter station,the active power-frequency sag control strategy and reactive power-voltage sag control strategy were improved by referring to the virtual synchronous generator. Finally,a simulation model was built,and the simulation results show that the converter station can provide frequency support and voltage support through the control strategy when the load is sudden.
