Abstract

Compared with traditional substations, the secondary circuit of smart substations is quite different in terms of transmission channel and protection function realization, which puts forward higher requirements for the knowledge level and business capabilities of smart substation operation and maintenance personnel. It is necessary to develop a set of teaching tools suitable for the training of secondary circuits in smart substations. This paper proposes a set of smart substation simulation secondary circuit simulation training system. The system builds the dynamic drawing model of the secondary schematic diagram, secondary wiring diagram, and secondary expansion diagram of the smart substation through visual modeling tools; with the help of the drawing monitoring module, the system can monitor the status of drawing elements in real time, dynamically calculate the input and output of drawings, and record the action sequence of elements; the system can build training cases based on typical protection action events and alarm events of smart substations. Thus, the system can be used to carry out drawing recognition training and defect tracking training for the secondary circuit of smart substations. This system enriches the content of the simulation training of smart substation secondary circuit, and has achieved good results in practical applications.
