| Abstract: | The authors analyzed the research background of wide area protection, summarized the current different types of wide area protection systems and re-delimited the functions of these systems. According to three kinds of power system stability problems which may affect power system security in varying degrees, this paper proposed a novel wide area protection system constituted by quick protection, stability and emergency control and system oscillation detection. The functions to be possessed and the working flow of the presented system were expounded. To establish such a system the authors also pointed out items to be researched. The proposed wide area protection system can offer rational security solution for interconnected power grids. |
