电力建设工程项目的经济评价已成为电网规划工作中不可或缺的部分。电网投资效益分析计算包括电量加价计算、线损分析计算、净现值计算、动态投资回收期计算及敏感性分析等,其中,对电量加价的计算是关键。投资效益分析法采用反算法计算电量加价部分,再用正推法计算净现值、动态投资回收期、利润率等。基于此开发的电网投资效益分析软件系统,易于应用,计算合理。
The economic evaluation of power construction projects has become an indispensable part of the power grid planning work. The investment benefit analysis and calculation of power grid includes calculation of price increase, calculation of line loss, calculation of net present value, calculation of dynamic payback period and sensitivity analysis. Among them, the calculation of price increase is the key. The investment benefit analysis method adopts the inverse method to calculate the part of the electricity price increase, and then uses the forward method to calculate the net present value, dynamic investment payback period and profit rate. Based on this development of power grid investment benefit analysis software system, easy to use, calculated properly.
