Abstract: For the override trip problem of power system in Zhaozhuang No.2 Mine, we analyze the reasons and summarize the main causes leading to override trip,which are the unreason of tuning method, undistinguished setting value caused by short-circuit and large difference of power system operation. In order to solve this problem, we propose a set of anti-override trip power system based on intelligent substation centralized control area. Besides, the program achieves rapid exchange of information among monitoring-control equipment with the method of GOOSE technology and fast fault isolation technology. In addition, the scheme improves the fast and selection of the protection by using the protective action of subordinate substation and the quick-break protection function, which prevents the happening of override trip.
