Research On Evaluation Theory And Application Of Sustainable Development Capability For Thermal Power Plant

Enterprise's sustainable development is a theoretical innovation of sustainable development in soc-economy and has important significance in theory and practice. Sustainable development is a new development concept which gradually grows up in the seventies of the 20th century,it is a major breakthrough in cognition and this is formed under the practice of human exploration and rational understanding of reflection,but also it is an attribute of the human's thinking way and concept of update.Enterprises development model based on sustainable development is a new topic which depends on the socio-economic sustainable development theory.The meaning of this pattern is not only that the economic benefits of enterprise should increase in continuous,but also it should emphasizes Social responsibility and the harmony between the enterprise and the local social economic circumstances,natural environment.The study of thermal power plant's sustainable development has important significance in practice.Thermal power plant is the consumption of resources-oriented enterprise;it must consume a lot of fossil energy and other resources in production process.Meanwhile,it also discharges harmful substance and destroy the natural environment to some extent.It will improve the level of energy use and promote the protection of the environment through the analysis and comprehensive evaluation of sustainable development energy for thermal power plant.Analysis and conclusion have been made to the factors which influence the sustainable development of thermal power plant.The factors can be divided into three aspects:the external environment,the company's inherent competitiveness and the enterprise's external efficiency.The external environment contains political and economic environment,market environment;the company's inherent competitiveness includes company's performance level,technique level,capital strength,human resources management level and integrated management level;the enterprise's external efficiency contains the environmental benefits,political and economic benefits of the enterprise.The sustainable development index system based on harmonious development of enterprise is established,which can be divided into four layers.Subject layer is sustainable development energy for steam-power plant,this is the first layers which have three indexes:the external environment for enterprise systems(constraint condition),the enterprise's comprehensive competitive power(the own quality),the enterprise's external efficiency(impact output),the second and the third index system are the disintegration of the fist index system,the forth index system is the specific measurement indexes.We proposed a new evaluation method:a sustainable development evaluation model for thermal power plant based on SA-BP neural network.Artificial neural network is an advanced intelligent evaluation method,but it is too easy trap in local optimum when calculate.This new model(SA-BP) can overcome the disadvantage when evaluate with ANN method.It builds a sustainable development evaluation model for thermal power plant based on SA-BP neural network.With this new method,it can jump out of local minima to overall small in evaluation process,and it also can increase learning speed and precision approach system.Application analysis is made for 10 thermal power plants in the paper.Compared with traditional evaluation methods;there are some advantages of SA-BP neural network evaluation model such as more accurate and more convenient.Moreover,it doesn't have to analyze the relation among the influential factors,and it will not influence the evaluation result when other not important factors are input the database.This new model can evaluate the sustainable development capability for thermal power plant in accuracy.
