Feasibility Research on Adopting HVDC Centralized Control in China

In this paper firstly the present situation of HVDC power transmission systems in China is analyzed;then the problems such as implementation of automatic management scheme for centralized control of HVDC,structural planning of control system,its technical and economical feasibility,and future development are researched. Research results show that there are conditions for the implementation of centralized control of HVDC,and it is feasible in technology,the further research on its design and implementation is necessary as well. With appropriate centralized control of HVDC,power grid enterprises can obtain benefits in many aspects;lay the foundation for the implementation of advanced auxiliary control strategy;and further give full play of HVDC in the improvement of power grid security and stability.
