当前全国各地的规划、设计部门,正在运用《小水电经济评价暂行条例》(以下简称《条例》)对小水电工程进行可行性研究。笔者从某些设计文件的经济评价章节中,发现在运用《条例》的计算一、对工程投资K_0是工程投资折算到基准年的总值,基准年可以随意选定,《条例》推荐取工程基本建成达到设计效用(正常运行)的年初为基准年。如果按此选定,则一般情况下基准年后是不再有项目投资的,因而可以按下式计算:
Currently, the planning and design departments throughout the country are using the “Provisional Regulations on the Evaluation of Small Hydropower Hydropower Economics” (hereinafter referred to as the “Regulations”) to conduct feasibility studies on small hydropower projects. From the economic evaluation section of certain design documents, the author finds that the calculation of the “Regulations” is used. 1. The project investment K_0 is the total value of the project investment converted to the base year. The base year can be arbitrarily selected. The “Regulations” recommend the project The base year of the year when the basic construction was completed to achieve design utility (normal operation) is the base year. If this is selected, the project investment will no longer be available after the base year, so it can be calculated as follows:
