Therefore, power grid planning will face a long-term and arduous task. To meet the power demands from the social development and people’s livelihood in the future, a large number of coal-power projects have to be installed, which tightens the situation of coal supply, transportation and environmental protection, lowering the efficiency of energy configuration. Therefore, to secure the harmony between China’s energy and the development of economy and society, it is necessary to build long-distance, great capacity and low HV power transmission system; it will also help to improve the framework of the power grid and enhance the safety of the power grid; it also will help to decrease the cost for the construction of power grid, to save land resources, to relieve the pressure of transportation and environmental protection, to improve the management efficiency and promote the construction of energy-saving and environment-friendly society. Based on the height of the global strategy, our country national HV power grid planning problem is studied in this paper.
