Research On Risk Assessment Of Gas Turbine Project Schedule Under DB Mode

With the rapid growth and constantly improve the level of social productivity and economy, the demand for energy is also growing rapidly. At present, the world of power station turbine dominant situation has started to shake, "large power plant unit, mainly in small units, with combined heat and power for the majority" has been the main pattern of plant development in many developed countries. Gas turbine has the advantages of highly fit, can be used as a variety of power generation mode, to become one of the main form of the world power, because the device, especially the combined cycle power generation device has the advantages of high efficiency, good mobility, can not only be used as peak load unit grid, and more for base load power grid, and can to meet the increasingly stringent environmental requirements, its position will be consolidated and strengthened. Since China’s reform and opening up, with the rapid development of power industry and the peak valley difference increasing, gas turbine power generation has been paid more attention and developed. In recent years has been the construction of a number of international advanced level of units, to alleviate the shortage of electric power at the same time, effectively play the role of enhancing the peak load capacity of power network. With the development of science and technology, energy policy adjustments, how efficient and clean utilization of fossil energy has become a prominent problem in the field of electric power. Gas steam combined cycle power generation more and more national attention, should be developed further.Gas turbine from manufacture to installation and commissioning to the last generation, the process is long and complex, the paper mainly uses the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method, the schedule risk of project of gas turbine.The author takes Wuxi gas turbine project as an example, analysis for this project, mainly includes the overview of Wuxi city gas turbine gas turbine project, Wuxi project risk identification, using the analytic hierarchy process (AHP) index of Wuxi gas turbine project schedule risk identify, determine the schedule risk of project based on fuzzy comprehensive evaluation method.
