Abstract
To prevent the manual switching failure events of auxiliary power system that are caused by unreasonable setting of switching mode under different connection modes or incorrect value setting in application, the influence of power angle of auxiliary power system on parallel switching mode is discussed by taking the example of the switching of auxiliary power system under several different connection modes. Then the impact of impulse current on series switching when start-up transformer is under stand-by heat and stand-by cool mode, the problems of impulse current and bus voltage failure during all switching are analyzed. In addition, the calculation method of maximum loop closing angle of parallel switching for auxiliary power system is given. At the same time, the issue that load is not permitted to completely fast switch under connection mode of two units sharing same start-up transformer is pointed out, and the same switching mode is suggested for this case. The selecting method of the switching mode for auxiliary power system under different connection modes is put forward according to analysis results.关键词
