Research on Distribution Network Fault Simulation Based on Cyber Physics System

The coupling effect between power system and communication system is becoming more and more complex. While the controllability of distribution network has been strengthened, it also has a stronger dependence on information control system. This paper presents a method of distribution network fault simulation based on cyber physical system (CPS). A terminal CPS fusion model based on finite state machine is constructed. Distribution network fault simulation is carried out under Distributed Denial of Service (DDOS) attack. The feasibility of terminal CPS fusion model based on finite state machine is verified, and the actual distribution network fault handling is realized. The simulation fully simulates the interaction process between physical and information in the actual distribution network fault handling process, verifies the correctness of the method proposed in this paper, and analyzes the impact of communication environment on fault handling.
