Research On Post-evaluation System Of Power Grid Project

Now post-evaluation of studies have enter into a more mature stage, however, specific types of post-evaluation study have rarely been found. To solve this problem, this thesis proposed post-evaluation of power grid project research. Usually post-evaluation has been studied in different aspects of project evaluation research, The thesis proposes the concept of the post-evaluation system, and will be divided into three aspects of indicators research,data analyze and methods of research based on the concept ,then the studies will be proved to be true by analyzing case.First of all, by using system theory, the study of indicator evaluation is divided into primary target indicators and targets indicators, the validation. Then the initial set of indicators will be established by selecting the method of analysis and the method of questionnaire survey and clustering analysis are used to carry out filtering. The feasibility of a single index, the coverage of overall index and information will go through the process of the filtering indicator system. Ultimately, the thesis establishes the final set of indicators of the power grid post-evaluation system.Secondly, through literature review, the target indicators set of network after a subject appraisal system will be separated into the known and unknown. According to different characteristics of evaluation systems, the thesis will propose the access channels of the process of appraisal target indicators set. By design questionnaire survey matrix, the impact indicators to evaluate can be developed. Network technology performance appraisal target indicators can be calculated through the clear formula. By analyzing the constitution of indicators, and define the data to predict which is purchase tariff and electricity consumption. Time series method uses the right way to predict electricity price. Regression method can be used to predict electricity consumption. Finally the date which is required in network after a project appraisal can be obtained. Thirdly, the process of analyzing information will divide the research of the power grid post-evaluation method into indicators weight calculating method and evaluation methods. Through analyzing the applicability of those methods,the way of calculating indicators weight is the method of relationship of the order, the post-evaluation method applies to the principles which is easily to apply and combine with the method of relationship of the order. The power grid post-evaluation project will use the method of fuzzy comprehensive evaluation of projects.Finally,the article quote in the case, determine the specific evaluation indicators and its weight, use fuzzy comprehensive method to evaluate, and finally develop the power grid post-evaluation.
