Design and Implementation of Wind Farm's Power Prediction Web System

摘要

In this paper, a web system for Wind farm power prediction is presented. By using annotation-based Spring 3 platform and technologies including FreeMarker and JFreechart, process of web design is simplified and quickly finished. In addition, the web system can be easily maintained and expanded. Finally, the establishment of wind power prediction web system is convenient for bidding of power market and maintenance of wind farms. Usually, wind farms are located in remote area and wind turbines belonging to the same wind farm are not in the same area. It is difficult for the dispatching and the management departments which are far away from wind farm to obtain data, such as power generation and the changing wind speed. So, it is necessary to build a distributional, open and real-time web system to predict power of wind farms. As the development of Internet and web technology, it is easier to apply web according to different and complex enterprises demands. And the focus of web design was to make application more convenient, more powerful and more flexible. In this paper, in order to design the forecasting web system, the lightweight container Spring3 was taken as a development platform, Spring MVC as web framework, Spring JPA as data persistence technology, Spring Security3 as Web security management. Moreover, FreeMarker was adopted as view template and JFreeChart as figure display tool. The web system provides the dispatching and the management departments with an information sharing platform which is safe, efficient, stable, extendible and easy to be maintained.
