The Green And Harmonious Post-Evaluation For Construction Project Of Thermal Power Plant

As power projects are both technology-intensive and capital-intensive, the construction of a thermal power plant requires massive financial, human and material resources. Once completed, they have to keep on operation for decades and will not be able to transfer to other businesses even if significant changes occurred in the objective environment and its own state. As a result, power projects are not only put at risk during construction period, they are also largely exposed to risks during operation period due to constant changes of external conditions. Whether a power project adapted to the demands of times can be built up is the key to effective management and decision-making for government administration departments and various investment subjects. It is the urgent desire of both investors and relevant government institutions to carry out green and harmonious post-assessment for thermal power project, which furthermore gathers experience for future project development, investment, construction decision-making and management and even provides theoretical basis for guiding investment orientation.The concept of green and harmonious post-assessment concept is put forward. Combing the characteristics of power market reform and macroeconomic environment in China, this paper elaborates the background and significance of green and harmonious post-assessment for thermal power project in China. Investigating relevant thermal power plant post-assessment criteria as well as currently available research findings of thermal power projects, the significance of green and harmonious construction to thermal power project post-assessment is analyzed and the basic principles and ideas for establishing green and harmonious post-assessment index system of thermal power project construction is advanced.The index system of green and harmonious assessment is brought up. The ordinary comprehensive assessment for thermal power projects can not reflect the green and harmonious benefits the thermal power project brought to the community. This paper builds the green index system from the aspects of energy saving, comprehensive utilization of resources and pollutant control and etc.; it builds the harmonious assessment index system through the angles of internal harmony of project, namely harmony between human, harmony between human and equipment, harmony between human and environment, harmony between labor and management, harmony of project intrinsic economic efficiency, as well as harmony between project and external surroundings, namely harmony between project and society, harmony between project and natural environment, harmony between project and economic environment and harmony between project and market environment.This paper proposed a hierarchical fuzzy comprehensive assessment model based on "feature-driven" and "difference-driven" combined weight. Eigenvalue method and entropy weight method are based on "feature-driven" and "difference-driven" approach respectively to determine the weights. With a structure design of "hierarchical model" and "fuzzy comprehensive assessment", this paper constructs a hierarchical fuzzy comprehensive assessment model based on the "Function Driver" and "difference-driven" combination weights. The assessment results shows that this assessment method adapts to the assessment system proposed in this paper, which combines the advantages of both subjective weight and objective weight, thus possessing an open and transparent nature and to a certain extent, ensures the inheritability.The preferred combination forecasting model based on hidden Markov models and time series multiplicative is proposed in this paper, which is adopted to forecast indicators in need of prediction in post-assessment system and satisfactory forecasting results are attained.The 2×600MW thermal power project in Sanmenxia, Henan, China is taken as a case for green and harmonious comprehensive assessment. Based on the assessment result, effectiveness is shown, problems are analyzed and suggestions are put forward concerning various aspects of green and harmony for more extensive reference.
