The Research Of Assistant Decision-making In Rural Grid Network Planning

The scientific planning scheme is a good basis for the structure of the grid. Doing a good work of planning ang design plays a decisive role in investment cost of engineering construction and comprehensive economic benefits of operation. At present, the rural grid network planning is mainly finished by the planners via handcraft, that's great elective. This text strives to make a more perfect rural grid network planning model and asks solution with computer in order to receive more economic decision scheme.Load forecasting is the prerequisite and basis for the grid planning. In chapter two, this literary uses the grey model and the regression model to forecast the total load, and uses the technology of optimizing grouping which synthesizes the advantage of every method to obtain the systematic total amount of load. In addition, according to the characteristics of the town's electricity growth, we divide its' electric load into two parts, that's the part of natural increasing and the part of jumping increasing. We use the model of Logistic in demology to forecast the part of natural increasing and adopt the model of fuzzy synthesis judging to analyze the part of jumping increasing. So go on, we can get a certain every district town load of rate at the same time.The optimization of the substation's site and the choice of the capacity are the important factors in influencing the grid structure and the construction investment of the grid. In chapter three herein, the author seeks to conduct an in-depth analysis on this issue. At first, I sets up the model of optimizing substation halt of many stages and confirming capability, which stands on the basis of selecting sites with many continuously sources. Employ, the author uses the theory of the most little tree and the most short road in the theory of chart to discuss the issue of selecting site with single source. At last, using computer as a tool, I solves the actual matter.Network planning is the key technology in grid planning. This text establishs the...
