Operation Tickets Automatic Generation Method in Intelligent Substation Based on Rule Reasoning

The operation ticket generation system of the intelligent substation can effectively prevent disoperation and achieve the sequential control. At present, however, the operation logic of the system is mainly based on the typical bay, with manual configuration and heavy workload. To solve this problem, a method of automatic generation of operation tickets based on IEC 61850 is proposed in this paper. First, the basic unit model is established based on the "Five Prevention" rule, the operation rule functions of various typical bay devices are generated to realize the construction of the system knowledge base. Second, the state of primary equipment is obtained by analyzing the SSD file of the intelligent substation to construct the primary equipment topology table and the inference mechanism is constructed by using the inference algorithm based on the equipment state and the equipment operation rule function to realize the automatic generation of the operation ticket. Finally, an example is given to illustrate the effectiveness of the proposed method.
