The cost and income of analysis hydroelectric engineering
In the feasibility study stage of hydropower project, the cash balance of investments must be predicted in subsequent various periods, and on this basis, the economic effect of the investment project has to be analyzed, calculated and finally determined whether it is feasible.
Fig. 1 The cost structure of hydropower project Fig. 2 Hydropower project risk quantification Because of the complexity of hydropower engineering and non repeatability, it is difficult to accurately analyze and quantify various risk factors by the objective probability.
For example, in the process of hydropower project construction, geological conditions are of greater uncertainty, correspondingly, the engineering cost effect can be described using the uniform distribution; For the certain risk factors with less information, the triangle distribution is the first choice.
