A Research Of Jincheng Power Network Dispatching Visualization And Intelligent Analysis Of Early Warning

With the multiplication of the number of transportation substations,the scale of the power grid is becoming more and more large,the structure of the grid is becoming more and more complex,and the information of the state of the power grid is becoming more and more huge.Therefore,how to present the raw data of the power grid to the dispatcher in an intuitive and convenient way,and to improve the ability of dispatchers to control the complex large power grid have become a major challenge for the development of strong smart grid.Aiming at the actual demand of dispatching in Jincheng power grid,the visualization and intelligent early warning system of Jincheng power grid is designed,and the main functions of the system are realized.The main functions and features of OpenGL software system is analysised;The three-dimensional visualization platform based on grid data is built combined with SCADA/EMS and OpenGL;According to the actual situation of Jincheng power grid,the design of intelligent early warning system is completed.Four aspects of the problem are studied in this paper,including real-time monitoring and analysis,static stable security early warning,voltage stability security early warning and the research of state calculation.And the corresponding realization method is given.Finally,the interface and function of the dispatching visualization and intelligent early warning analysis system of Jincheng power grid are introduced.The paper designs and achieves the Jincheng power grid dispatching visualization and intelligent early warning analysis system.It has strong power grid monitoring function.It can automatically identify the real time security risks in the system,and give a solution to eliminate hidden dangers,which can effectively reduce the labor intensity and difficulty of staff.Especially,it greatly reduces the degree of mental stress of dispatchers,and improves the safety,accuracy and rapidity of dispatching operation in Jincheng power grid when the power grid emergent failures.The design and successful application of the system has the great significance for ensuring the safe and stable operation of Jincheng power grid,and for the development of Jincheng power grid and the construction of smart grid.
