Research and Application of Power Supply Path Trace in Integrated Dispatching/Distribution Automation System

This paper proposes a method of power supply path trace suitable for integrated dispatching/distribution automation system. It can realize the target device’s trace function of superior power supplies, its retrieval scope can extend to 220kV high voltage looped network, and the highest voltage level it can reach is up to 500kV. The power supply path presents directly as automatical mapping, which can reflect the power supply safety, trace process and trace result dynamically. This paper demonstrates the basic principle of the function realization, provides technical researches of power supply path tracing and automatical mapping based on integration modeling technology of dispatch. It can follow the full power supply path and observability of power supplies with higher voltage levels. The correctness and effectiveness of the proposed method are verified by different functional scenario analysis and application examples.
