Research on technical and economic of the 1 000 MW unit two unit one tower project
In order to compare the technical and economic feasibility of the 1 000 MW unit two unit one tower project,the 2×1 000 MW unit of a power plant expansion project in Anhui Province taken as the research object,a two machine one tower high-level tower scheme,a one machine one tower high-level tower scheme,and a one machine one tower conventional tower scheme have been proposed.The scheme was calculated by using the dynamic payback period method.The results show that the initial investment of the two machine one tower high-level tower scheme increases by 46.61 million yuan,which can save about 7.166 3 million yuan per year in operating electricity costs.Calculated based on an annual utilization hour of 4 750 hours,the dynamic investment payback period is 8.1 years,which is less than 10 years.Therefore,the two machine one tower project is feasible.
