Benefits Analysis Of Gas Turbine Power Generation Projects Under Lifecycle

Gas turbine power generation as a major form of power generation has been supporting regional power and heat supply. Meanwhile, the developing of gas turbine projects gives direct impetus to adjusting the energy structure and deepening the energy conservation and emission reduction of China. Such projects provide certain support for regional peak load dispatch, with visible feature of clean and environmentally-friendly. Focused on the economic efficiency of gas turbine projects, the evaluation and optimization analysis system for lifecycle economic efficiency of gas turbine projects is studied, providing certain reference basis for comprehensively improve the evaluation level of economic efficiency and capability of sustainable development of gas turbine projects.The research is carried out from the following aspects.The macro background of gas turbine project developing is analyzed, the features and major problems during the development are described, and the basic theory on the economic efficiency analysis is studied.The evaluation system for the lifecycle economic efficiency of gas turbine projects is built, which is considered from two main steps-investment and operation, and three main benefits-economic, environmental and social benefits,the particularity of economic efficiency evaluation is also considered. One of the gas turbine projects is selected to implement empirical analysis, the main economic efficiency indexes are described, an evaluation model based on Delphi with AHP is proposed, and the detailed empirical computing is given.Based on the empirical analysis, the life cycle optimization is deeply analyzed. The method for the measurement of economic efficiency influence factors is proposed based on Fuzzy Bias, energy conservation and emission reduction and peak dispatch are introduced to help analyze the advantages of environmental and social benefits.The research results provide certain theoretical reference for the scientific evaluation of the economic efficiency, but also put forward suggestions to the sustainable development of deepening gas turbine projects.
