Modeling and Simulation for Performance Evaluation of Distribution Network Communication Systems

A custom designed distribution network communication systems can maintain the fast and reliable information transmission and lead to improved operation and management of a distribution automation system. In this paper, the distribution automation transformation scheme of a regional power grid is analyzed. Then a simulation model of three types units, including the intelligent distributed protection unit, the three-remote unit and the master station unit, is constructed based on the Optimized network engineering tool (OPNET) Modeler platform, which is the main novelty of this paper. Finally, an intelligent distributed protection system is constructed and simulated using the models. The simulation results show that the models can act an effective tool to analyze the network performance, which can provide a quantitative basis for the design of the distribution network communication systems.
