Research And Application Of The Power Grid Data Show Based On The Web-SVG

With the urban's construction and social development of our country, Society needs more and more on electricity, the importance of the power grid information is becoming more and more prominent, therefore establish a intelligent information power grid will be the inevitable trend in the development of electric power industry, facing the complicated production management, considering the grid security and efficiency in production, the leadership of grid enterprises and other administrative departments at directing production and management, need understanding of grid real-time, historical information for power system comprehensive information timely, so that they can make the right decision for the state evaluation, production planning etc of power grids.This paper is based on power grid data display, on the basis of previous literature research, based on relevant documents of power grid and electric company actual demand, analyzes the reason of the SCADA system can't be used as the display platform for the department outside of scheduling directly, put forward the scheduling real-time information display and curve analysis system based on the Web-SVG is feasible.In data storage aspects, this system create corresponding database and data sheet according to the power grid data types and characteristics, as to the real-time data storage adopted longitudinal table, historical data store in transverse table according to the policies. In data show, this system adopts Myeclipse development software, using J2EE language, development is based on B/S structure, the browser using Ajax asynchronous request technology,use the scheduler's periodic automatic function calls of browser to realize the automatic periodic request, backend server using Weblogic9 for business logic analysis, query and retrieve relevant data in the database and return these data to the browser, it cooperates with the JS script of browser, make asynchronous request of XMLHttpRequest Object and SVG picture DOM be together, display the real-time information data changes dynamically. This system platform can real-time release and display scheduling real-time information, SVG once hookup, grid history data, curve analysis and show real-time and historical data. Considering the safety, system realizes the personnel access permissions and role of combined, prohibit permissions and permission combination. The research of scheduling real-time information display and curve analysis system based on Web-SVG has a very important significance for power system security, economic and stable operation.
