Abstract
Voltage quality is critical to the security and economic operation of power system and the security and life of power equipment. In this paper, the probability statistics and vector algebra methods are used to set voltage deviation and fluctuation indexes, and the multi-period voltage quality comprehensive evaluation approach is also built. Then, the voltage quality of CSG 500kV plants and substations is analyzed by using of proposed method, the common features of voltage during weak period of different stations and different periods are presented, and the cause of relative weak voltage level in some substations is also analyzed. The proposed method can provide accurate quantitative index, which helps for adapting different controlling strategies as to the features of voltage during different periods, and improve the voltage quality of CSG furthermore to guarantee the security and stability operation of power grid.关键词
