The invention relates to a method for positioning a fault channel of a process layer physical loop based on a station level signal. The method comprises the following steps: carrying out association mapping between the station level signal and a process layer virtual loop; based on virtual-real mapping interaction between a virtual loop and a physical loop in the process layer, binding the station control layer signal after association mapping with the whole-station physical loop of the process layer; splitting the whole-station physical loop into fault sections according to the whole-station physical loop corresponding to the virtual loop in the normal state, and generating a signal fault comparison table; and through data comparison of the fault comparison table, positioning of the process layer physical loop fault channel is completed. According to the method, virtual-real mapping can be performed on the process layer through station control layer signals, and the working efficiency and correctness of operation and maintenance personnel are effectively improved.
Description
technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular relates to a method for locating a process layer physical circuit fault channel based on a station control layer signal. Background technique [0002] At the present stage, the smart substation mainly adopts optical fiber communication to replace the traditional cable connection mode. Choosing the optical fiber communication mode will bring huge positioning difficulties to the relevant operation and maintenance staff when a fault occurs. [0003] The smart substation consists of three layers and two networks. The two networks are divided into the station control layer network and the process layer network. The third layer is divided into the station control layer, the bay layer and the process layer. The bay layer equipment includes relay protection and measurement and control Intelligent secondary equipment such as devices, and process layer equipment i...
