1000 MW机组两机一塔项目的技术经济性研究

Research on technical and economic of the 1000 MW unit two unit one tower project

为了比较1 000 MW机组两机一塔项目的技术经济性,以安徽某电厂扩建项目2×1 000 MW机组为研究对象,拟定两机一塔高位塔方案、一机一塔高位塔方案、一机一塔常规塔方案,利用动态回收期法进行计算。结果显示,两机一塔高位塔方案的初投资增加4 661万元,可节约运行电费约716.63万元/年,按年利用时长4 750 h计算,动态投资回收期为8.1年,小于10年,两机一塔项目可行。

In order to compare the technical and economic feasibility of the 1000 MW unit two unit one tower project,the 2×1000 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 7.1663 million yuan per year in operating electricity costs.Calculated based on an annual utilization hour of 4750 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.
