China Southern Power Grid (CSG), of which the main grid consists of 500 kV transmission lines, is characterized by long distance, high capacity and AC/DC parallel transmission, and there are clear problems of thermal stability and standard-exceed short circuit current in its main grid. Considering the features of CSG operation, this paper does the classification of the above problems, and proposes corresponding solutions for various classifications through economic and technical comparisons. In addition, based on the development plan of wind power in Yunnan and Guizhou, the influence of these wind power integrated to the main grid on its stability and the potential impacts of the DC projects in construction in CSG are analyzed.
