Research and Application of Dispatching Misoperation Prevention System for Integrated Dispatching and Controlling

摘要

The possibility of dispatching misoperation under integrated dispatching and controlling and the defects of the existing dispatching misoperation prevention system were analyzed. A method about the integration between real-time data from dispatching SCADA system and data from substation misoperation prevention system was proposed, to solve the problem of incomplete high voltage equipment position in dispatching SCADA system; A method about the combination of the misoperation prevention check on instruction ticket and the online misoperation prevention locking on remote operation was proposed, to make up for the deficiency of the existing dispatching misoperation prevention system; A method about the hierarchical analysis on the grid topology was proposed, to improve the rate and efficiency of the online operation topology analysis. A novel dispatching misoperation prevention system was designed. The system has been put into application. The research result can be used as a reference for construction of integrated dispatching and controlling.
