Embodiment 1

[0035] Such as figure 1 As shown, a power grid economic evaluation data processing system based on full life cycle cost, including an improved financial evaluation index processing module 1, an efficiency index processing module 2 based on full life cycle cost and a minimum grid electricity price index processing module 3, in

[0036] The improved financial evaluation index processing module 1 takes the whole life cycle cost data, newly added cash inflow data and newly added cash outflow data as input data during the research period, and outputs financial net present value data, financial internal Rate of return data and payback period data;

[0037]The performance index processing module 2 based on the whole life cycle cost takes the whole life cycle cost data in the research period as input data, and outputs the direct economic benefit performance index data and the indirect benefit performance index data after calculation and processing;

[0038] The minimum on-grid elect...

Embodiment 2

[0077] refer to figure 1 As shown, this embodiment takes a 500kV power grid in an actual area of ​​China at the beginning of 2012. On this basis, the brief tables of newly added stations and newly added lines of the two sets of planning schemes are shown in Table 4 and Table 5. In the case of a newly added station, a new transformer is used instead, and the corresponding cost parameter adopts the comprehensive cost value. The cost value of the comprehensive construction cost in 2012 is the actual value of the current year, and the cost values ​​of other years are predicted by combining the trend extrapolation method and the gray system method. Obviously, both sets of planning schemes are multi-stage planning schemes from 2012 to 2015, and the life cycle of new equipment is different. The two sets of planning schemes both meet the reliability and safety requirements of future power operation in the region, so further economic evaluation can be carried out to select the optima...

Abstract

The invention relates to a power grid economy evaluation data processing system based on life cycle cost. The system comprises an improved financial evaluation index processing module, an effect index processing module based on the life cycle cost and a lowest on-grid price index processing module. After calculating and processing input data including life cycle cost data, newly increased cash inflow data and newly increased cash outflow data within a research period, the improved financial evaluation index processing module outputs financial net present value data, financial internal-rate-of-return data and investment payback period data. After calculating and processing the input data, namely the life cycle cost data, within the research period, the effect index processing module based on the life cycle cost outputs direct economic benefit effect index data and indirect economic benefit effect index data. The lowest on-grid price index processing module is used for calculating the lowest on-grid price data. Compared with the prior art, the power grid economy evaluation data processing system based on the life cycle cost has the advantages of objectivity, comprehensiveness, accuracy in evaluation and the like.

Description

technical field [0001] The invention relates to a data processing system for power grid economic evaluation, in particular to a data processing system for power grid economic evaluation based on full life cycle cost. Background technique [0002] Economic evaluation is an important means to make scientific and democratic decision-making of engineering projects, reduce and avoid decision-making mistakes, and improve economic benefits of engineering projects. According to whether the time value of funds is considered, economic evaluation is mainly divided into static evaluation method, dynamic evaluation method, and uncertainty economic evaluation method. Among them, the dynamic evaluation method considers the time value of funds, adopts the method of compound interest calculation, and converts the costs at different time points to the same time point for comparison, which is the main cost evaluation method. The traditional content of economic evaluation includes financial ev...
