Power grid asset revenue calculation method and device based on power grid topological relation

Abstract

The invention provides a power grid asset revenue calculation method based on a power grid topological relation, and the method comprises the steps: building a power and electric quantity balance model of a power grid, determining an electric quantity transmission relation among all voltage levels, and sharing assets of the power supply voltage levels to a power receiving voltage level according to the total electric quantity and power supply proportion of all voltage levels; constructing asset redistribution model, achieving redistribution of assets of all voltage levels, and then constructing a cost collection model and an electricity selling income collection model according to an electric power and electric quantity balance model and the asset redistribution model, so that redistribution of the cost and the electricity selling income of all the voltage levels is realized; and finally, based on the power grid topological relation, the electric power and electric quantity balance model, the asset redistribution model and the electricity selling income collection model, respectively collecting the total income of each voltage level to the transformer substation, the power transmission line, the transformer area and the single equipment, thereby realizing accurate measurement and calculation of the income of the transformer substation, the power transmission line, the transformer area and the single equipment in the power grid assets.

Description

technical field [0001] The present invention relates to the field of electric power technology, and more specifically, to a method and device for measuring and calculating the income of power grid assets based on the topological relationship of the power grid. Background technique [0002] Electric power enterprises are relatively typical asset-intensive enterprises, with a large number of fixed assets, various types and wide distribution. In order to quantitatively reflect the investment benefits and operational efficiency of power grid assets, objectively evaluate the value contribution and creative ability of each business link, deeply analyze the weak links of key value chain activities, and provide scientific and quantitative information for the company's power grid planning and design, equipment procurement, operation and maintenance, and decommissioning transformation Analyze the basis for decision-making, accelerate management transformation, measure the specific ben...

Problems solved by technology

[0003] However, due to the complex topological structure of the power grid, the revenue of the power grid can only be gathered in the station area, and is not directly related to other specific assets of the power grid, such as substations, transmission lines, and power grid equipment. Value contribution of lines and grid equipment
