The HAVC system can improve the power system's voltage dynamic performance, enhance the voltage stability, and decrease the power grid's losses. Firstly introduces the model of HAVC system has been introduced, and the HAVC systemic framework has been designed for the 500kV power grid of Northeast China (PGNC). Also the power plant's HAVC control device has been implemented due to the practical instance. The physical dynamic simulations proved the validity and efficiency of the HAVC system's framework and device. 收起
