Research and Simulation on the Influence of Communication Faults in Electric Power System

Real-time wide area stability control of electric power system also increases the scale complexity and data transmission capacity of power communication network while realizing the interconnection of large interconnected power grids. The time delay caused by the randomness of signal transmission brings great difficulties to the analysis and control of the dynamic performance of the power system. In this paper, the problem of time delay and error code in communication network is analyzed, and the interaction between communication system and power system is analyzed by using the mathematical model of delay and error. Combined with the example of a provincial network and a particular power system, the effect of communication delay on the cascading failure of power and communication system is analyzed by OPNET simulation.
