The Study Of Online Supervisory And Analysis System Of Power Grid Based On Visualization

With the development of the scale of power grid and the appearance of the new technology,the amount of the power grid operating data increase rapidly.In the meanwhile,the occuring of the contingency become more and more undetectably.The traditional method of power grid real-time monitoring and analysis should not meet the development needs.The visualization technology which develops rapidly in recent years as a new technology can convert the data to the graphics or images showed on the screen by using the computer graphics technology.So it's application for the online supervisory and analysis system of power grid has great theoretical significance and application value.The paper describes the principles and concepts of the visualization technology and the application for the power grid operating。Then it study the visualization technology of the online supervisory and analysis system of power grid and the algorithm for the power flow cartoon,graphical calculation and voltage contour.Finally,the article makes the design and programming for the online supervisory and analysis system of power grid.The system has been applied in Dingxi power grid and proved its feasibility.
