Research On Investment Benefit Evaluation Of Motor Energy-saving Technical Revolution In Power Plant

Post project evaluation plays a vital role in the process of the entire project operation, analysis on the investment benefit is helpful to improve the project management and decision-making level.In order to response to state advocate of saving energy, accelerate the reduction and elimination of high-energy products and equipment, so power companies insist on increasing technical innovation in energy efficiency the input. Therefore, to improve the level of energy-saving technological transformation project evaluation has become an important issue, however, electric power companies in the energy-saving technological transformation project investment evaluation of the effectiveness and methods of the theory have many gaps to be explored further.This paper researches some problems undertook in energy saving technical reformation investment benefit evaluation, basing on the related theories and practice of power station. This article first elaborated the project investment benefit evaluation of the basic concept, theory and method; Secondly, analyzing the technical project and power industry energy-saving technological transformation projects, combined with its particularity, construct the project investment benefit evaluation index system, determined with AHP method and the entropy weight method a combination weighting method for comprehensive evaluation. Finally, taking the coal power plant of Shanxi province Pingshuo as an example, illustrating its fan motor liquid resistance energy-saving renovation project investment benefit evaluation, including the calculation of the index weight, index value calculation and analysis. Finally, getting the comprehensive evaluation value.The traditional investment benefit evaluation often only pay attention to financial index, the paper considers the characteristics of energy-saving technological transformation projects,, taking the technical factors into consideration in the investment benefit evaluation, establishing the corresponding index system, It has certain reference significance on the future of fire power plant energy-saving technological transformation project investment benefit evaluation.
