我局承担一座水电站的咨询项目,经过勘测设计,决定装机2×125千瓦,年平均发电量为119.21万千瓦小时,工程总投资46万元.本站虽已通过经济分析与财务分析,但实际上这些预估的数据可能在未来受某种因素的影响而引起变化,从而导致原来已定的经济方案可能不合理,因而有必要进行灵敏度分析,现论述如下.一、基本资料1.工程建设年限:m=1年;2.经济计算年限:n=40年;3.损耗率η_1:因为计算时应以有效电量计算,而有效电量是以本系统电力电量平衡确定的,
Our bureau undertakes the consulting project of a hydropower station. After investigation and design, it is decided to install 2 × 125 kilowatts with an average annual generating capacity of 1.1921 million kilowatt-hours and a total investment of 460,000 yuan. Although this site has passed the economic analysis and financial analysis, The above estimated data may be affected by some factors in the future caused by changes, resulting in the original economic plan has been set may be unreasonable, so it is necessary for sensitivity analysis, are as follows: First, the basic information 1. Engineering N = 40 years; 3. Loss rate η_1: Because the calculation should be based on the effective power calculation, and the effective power is based on the balance of the system to determine the power and electricity,
