Research On The Basin Cascade Development-based Hydropower Project Post-evaluation

Abstract:Hydro power project in power generation, flood control, irrigation,water supply, shipping, tourism,aquaculture and so on have important social and comprehensive benefits.Cascade hydropower development in investment, construction scale,long time span,wide scope,work in the entire project cycle decisions have strict requirements. Therefore, to gain fully basin project development experience,and to improve constantly the level of water conservancy construction of decision-making and management ability, is in the new period our country the key factors to realize the social,economic,ecological environment sustainable development in river basin.The project post-evaluation aims at summing up the experience of the project development process, to improve the project decision-making ability, increase the project development experience's important way. But the current lack of research on post-evaluation theory and method of hydropower engineering based on river basin development. Aiming at this problem,based on the related research at home and abroa, combined with the feature of reality of river basin development, combing the basic theory of river basin hydropower project post-evaluation and the mechanism of action,at the same time,by points and lines,first of all,on the base of hydropower project construction process,development goal, society and ecological environment influence four aspects,the basic composition unit of river basin hydropower development, individual hydropower project post-evaluation index system and evaluation method. Secondly, from the perspective of the overall benefit of cascade hydropower stations,this paper expounds the economic and development after the temporal evaluation of river basin hydropower development of theoretical framework and evaluation model.Finally, combining with the results of the above,taking YuanShui basin hydropower development projects for the object after the evaluation of the empirical analysis,verify the relevant theory of the scientific nature and effectiveness.Thesis research work is as follows.(1)We summarize river basin hydropower development post-evaluation theory system and the mechanism of action.System cybernetics and put forward the sustainable development of project evaluation theory are two basic theories of river basin hydropower project post-evaluation,the whole project management as a system,the former after the project evaluation is the important project management systems and control systems.Request for project construction should be the goal of sustainable development, fully considering the influence of the economic, social and ecological environment, achieve the goal of decision maximum comprehensive benefit;The basic principles of building hydropower project post-evaluation mechanism design,analyzes the project post-evaluation supervisory control function,analyzed the suitable for cascade hydropower project post-evaluation in our country3D management organization system and operational mechanism,which is suitable for cascade hydropower project design flow chart of the feedback, its purpose is theoretical analysis,the evaluation results can be smoothly after feedback to the decision-making, design, construction and operation units,for the project decision-making and construction control effect and significance.(2)Cascade hydropower the single project post-evaluation theory and methods.From the individual of the basin hydropower engineering construction process,the overall goal as well as to the society, natural environment, the evaluation on the four dimensions to examine the effects of to have dynamic control effect after the construction process of evaluation,combining with the actual construction process control effect after evaluation, discusses the individual hydropower project have dynamic control effect after evaluation content and evaluation method, and established the evaluation index system;Target for sustainable post-evaluation,combing the research scope of cascade hydropower project in sustainability, connotation,definition and characteristics,puts forward the concept of cascade hydropower project goals in the sustainable post-evaluation and basic content, to build the index evaluation system;Impact assessment for the harmonious development of society, analyses its basic contents,and builds the index system, and detailed analysis of the project and the social adaptability and resettlement evaluation content;After the environmental impact assessment study, cascade hydropower project in the ecological environment is constructed after the evaluation index system,establishing the ecological environment impact assessment matter-element-level analysis of coupled model.(3)Cascade hydropower project in economic benefits post-evaluation theory and method.From the national economic evaluation and financial evaluation after two aspects,delves into the overall economic benefit of cascade hydropower project in content, index system.In view of the river basin of compensation benefits of cascade hydropower project, introduced the general economic compensation benefits of cascade indexes after the evaluation index system, discusses the mechanism and compensation benefits of cascade hydropower project in index calculation method, and from three allocation methods,in-depth analysis of the cascade hydropower project benefit compensation allocation problem,gives the calculation method of three share ways?Is studied based on the DEA model of cascade hydropower project in the overall economic benefits after evaluation,constructs the cascade hydroelectric project in the overall economic benefits after evaluation of the theory framework of "static analysis and comprehensive evaluation", established the evaluation index system, puts forward the cascade hydropower project economic evaluation after the DEA model as a whole.(4) Cascade hydropower project development sequence in post-evaluation theory and method.Reviewed the basic mode of river basin development in the world, aiming at "valley, stair, rolling, comprehensive development" the principle of using the structural model analysis (ISM) technology, analysis of the cascade hydropower development in sequence after the evaluation of the key factors,discusses the development and utilization of the management mode of small and medium,large and medium-sized valley.This paper expounds the basic theory of fuzzy optimization model modeling, based on the fuzzy optimization model is put forward after cascade hydropower development evaluation model.(5)Post-evaluation of the empirical analysis after YuanShui river basin development project.The article introduces the situation;YuanShui river basin hydropower development. Using the analytic hierarchy process (AHP)combined with the expert scoring method,to post-evaluate YuanShui valley cascade hydropower project process;In qualitative analysis YuanShui hydropower project based on the factors affecting the sustainable evaluation of the project goal sustainability;Comprehensive analysis of YuanShui cascade hydropower development in the social environment factors;Evaluation of the engineering in power generation, navigation and flood control effect on yield zone, and analyzes the project resettlement; Using the fuzzy model of matter-elemen-level analysis for the YuanShui river basin hydropower project after the environmental impact assessment; By static analysis and comprehensive evaluation of two stage evaluation approach, using DEA model to evaluate the overall economic benefit of cascade hydropower development; Using fuzzy optimization model to calculate the ideal development timing, the project development situation,combination with the engineering practice of YuanShui cascade hydropower development in sequence post-evaluation. Comprehensive summary YuanShui the main conclusion of the development of cascade hydropower project puts forward the corresponding policy recommendations.Paper based on cascade hydropower project post-evaluation study, explores the theoretical system of river basin hydropower development after evaluation and function mechanism,analyze the hydropower project after single indicator of evaluation index and evaluation method, set up a cascade hydropower development in economic impact and development after the temporal evaluation of basic theory and evaluation model,the empirical evaluation of the YuanShui river basin development project. Thesis research work of cascade hydropower project evaluation related theory and application research has played a positive role in promoting.
