Research On Wide Area Standby Power’s Automatic Switch And Fault Recovery Strategy Evaluation For Regional Power Grid

Currently, self-healing is a majoi feature of smart grid, the power supply recovery for non-fault power lost area can significantly improve the curative property of power grid. Recent studies of various algorithms have achieved encouraging results in simulation experiment, but still there are few systems which can quickly propose solutions based on actual grid data and provide a graphical display.To meet the needs of enhancing self-healing in actual power grid, this paper proposes a design on wide area spare automatic switch and recovery strategy evaluation system with integrity and multi-method characteristics, and designs its core functions such as online checking, adjustment and fault recovery, etc. Combining the technology or theory of wide area spare automatic switch, graph theory, SVG graphic, etc, this paper develops a wide area spare automatic switch and recovery strategy evaluation system based on the power grid data of Xingtai.The system establishes the primary model of power grid and generates automatic modeling tools for wide area spare automatic switch, it accomplishes the online checking and adjustment function for the automatic generation of wide area spare automatic switch strategy when simple malfunction occurs by EMS system, this paper achieves the evaluation and application of multi-path recovery method based on the objective and subjective evaluation model of entropy law in complex malfunction condition, combining with CSS, JavaScript, Qt with many other computer technologies, this paper develops a graphical display platform based on the results of SVG recovery strategy and adds rich dynamic display effect to the graphical display platform, which greatly improves the system’s usability. Finally, this paper tests the designed system by simulating the fault information and further verifies the effectiveness of designed system.
