Embodiment Construction

[0046] Such as figure 1 Shown is the method flowchart of the inventive method: the evaluation method method of this grid project investment benefit provided by the present invention, comprises the steps:

[0047] S1. Classify the projects to be evaluated; the voltage level is classified according to 500 (750) kV, 220 (330) kV, 110 (66) kV and 35 kV and below power grid transmission and transformation projects; the function of power grid projects is based on meeting the load Classification of supply, power transmission, electric railway power supply, supporting transmission of substations, and grid strengthening projects;

[0048] S2. According to the classification result of step S1, construct evaluation index system; Can adopt AHP to construct evaluation index system, specifically comprise the following steps:

[0049] A. Taking the investment benefit of the project to be evaluated as the goal, divide the indicators related to the power grid project benefit evaluation into t...

Abstract

The invention discloses an evaluation method of investment benefit of a power grid project, which comprises the following steps of: classifying the items to be evaluated; constructing an evaluation index system; establishing the graph model of the index and quantifying it; calculating index weights of the quantized index graph model; performing quantification and dimensionlessness of the indexes;constructing a comprehensive scoring model to evaluate the investment benefit. The invention provides a method for evaluating the investment benefit of a power grid project, the evaluation index system considering the functional characteristics of the project is constructed, a graph model index weighting method is proposed and the differential evaluation results of power network projects based onfunction classificaiton can be obtained through a scoring module; the method of the invention can scientifically and reasonably evaluate the benefit of the investment of the power network project, andcan reflect the investment benefit of the different functional projects more accurately and quickly, and the method of the invention is scientific and reliable, and the calculation process is simpleand clear.

Description

technical field [0001] The invention specifically relates to an evaluation method for the investment benefit of a grid project. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. [0003] At present, the scale of my country's power grid is gradually expanding, the voltage level is gradually increasing, and the transmission network project is gradually being planned and constructed. However, the construction investment of power transmission projects usually has the characteristics of large scale and long payback period. In the face of huge and fast-growing investment trends, it is considered to analyze the investment benefits of the projects put into operation according to their functions, so as to confirm whether the expected goals...
