The Technique Research And Implementation Of The Power Grid Investment Evaluation Application System

Power Gird is the infrastructure and important resource that related the vitals of national economy. As the rapid development of national economy and the increasing people’s living standards,people’s demand for electricity is growing,investment on power grid is also increasing year by year. How to do reasonable investment, to Speed up the grid development and gain more benefit. Evaluation of the enterprise investment is key to the management,it provides Scientific basis for enterprise investment.The subject build a comprehensive investment evaluation model on the basis of full study on the characteristics of the grid investment.And research and development a investment evaluation system by using advanced software development techniques.System achieves building a flexible evaluation index system,by configure the index formula,achieve automatic calculation of the index value.By using data management model,calibrate index data in both integral and rational.Then getting quantitative result through calculating by using index data and investment evaluation model.System also impelement investment evaluation auxiliary analysis,to analysis index data in more finer-grained both in horizontal and longitudinal.System implement a rich display capabilities for analysing and displaying to make anlysis result easy to understand.System is developed based on J2EE,implemented based on B/S mode and build by using Ibatis+Spring+Flex as3framework.The application of the system provide scientific and reliable evaluation results for user.The result reflect the running situation and effectiveness of the power grid realisticly and provide a quantitative foundation for investment decisions,thus to improve investment decision-making.At present, the system has been put into use and achieved good results.The system is easy to use,versatile and has high promotional value.
