Problems solved by technology

[0002] At present, with the rapid development of the national economy, the electricity load in various places continues to grow, and comprehensive commercial and commercial areas, high-density residential areas, and economic development areas with different functions emerge one after another, and users at all levels have more diversified demands on power supply reliability. Under the situation of double growth of electricity demand and reliability demand, distribution network planning and reconstruction work project investment is facing enormous pressure, and long-term large-scale high-level investment will be unsustainable

Embodiment

[0050] Embodiment, the application example of Yangzhou City Power Grid, Jiangsu Province;

[0051] (1) There are four types of power supply areas in Yangzhou: A, B, C, and D. The current annual load density of the four types of power supply areas is 7.6000MW / km 2 、2.6403MW / km 2 、0.5098MW / km 2 、0.2388MW / km 2 In 2020, the load densities of the four types in the supply area will be 9.0000MW / km respectively 2 、3.1267MW / km 2 、0.6037MW / km 2 、0.2827MW / km 2 ;

[0052] (2) According to the voltage level sequence of substations in Yangzhou supply area, the number of main transformer configurations, capacity, and outgoing medium-voltage lines, etc., the power supply mode of Yangzhou supply area is selected as A, B, and A-3, B-3 and B-2 Mainly, C and D categories are mainly C-1, C-2, D-2, D-5, a total of seven typical power supply modes;

[0053] (3) According to the project investment model of the above-mentioned typical power supply modes, judge the most economical power supply ...

Abstract

The invention relates to a project investment calculation method based on a typical power supply mode, which comprises the following steps: 1) establishing a typical power supply mode scheme library; 2) establishing a typical power supply mode project investment model; 3) setting the boundary of the typical power supply mode project investment model 4) Select the only typical power supply mode; 5) Calculate the project investment model of the typical power supply mode, if the power supply area is a new area, calculate the investment Ca of the new distribution network project under the typical power supply mode; if If the power supply area is a reformed area, the current year power supply reliability rate RS1 of the power supply area is required 1 , and the power supply reliability rate RS1 of the annual planning target of the typical power supply area planning 2 In comparison, calculate the distribution network transformation investment Ca under the typical power supply mode. The invention is beneficial to standardization, quantitative evaluation, and standardization of power grid construction in each power supply area.

Description

technical field [0001] The invention relates to a project investment calculation method, in particular to a project investment calculation method based on a typical power supply mode used in the field of power grids. Background technique [0002] At present, with the rapid development of the national economy, the electricity load in various places continues to grow, and comprehensive commercial and commercial areas, high-density residential areas, and economic development areas with different functions emerge one after another, and users at all levels have more diversified demands on power supply reliability. Under the situation of double growth of electricity demand and reliability demand, distribution network planning and transformation work project investment is facing enormous pressure, and long-term large-scale high-level investment will be unsustainable. The typical power supply mode involves load density, voltage level, grid structure, reliability and economy, which i...
