Household average distribution transform capacity configuration method based on user behaviors

Abstract

The invention discloses a household average distribution transform capacity configuration method based on user behaviors, comprising the steps of: S1, calculating resident loads to obtain a calculated load Pjs; S2, calculating a distribution transformer load rate beta, and based on the calculated load Pjs obtained in step S1, calculating a distribution transformer capacity S and a distribution economic operation range; S3, determining a user number n; S4, calculating a household average distribution transform capacity Sav based on S1,S2 and S3; and S5, performing economic analysis on the distribution transformer capacity. The method can guarantee power grid safe operation, reduce power grid loss, improve power supply reliability and electric energy quality, effectively reduce distribution transform requirements and construction investment, improve the use ratio of electric power company manpower and material resources, achieve the purposes of saving electricity and reducing power grid operation costs, and allow a power distribution network to satisfy maximum electricity demands of social economy development and living standard improvement.

Description

technical field [0001] The invention relates to a configuration method of distribution transformer capacity per household based on user behavior, and belongs to the technical field of distribution network planning in the electric power industry. Background technique [0002] The research on the capacity of distribution transformers per household is an important content of regional power distribution system planning, which is directly related to the reliability of power supply in the region and the economic evaluation of transformation. Therefore, a reasonable selection of distribution transformer capacity per household can not only effectively Guiding power supply and consumption departments to make reasonable and economical investment also plays a key role in the energy-saving and economic operation of distribution transformers, and is more related to the national economy, the people's livelihood and the stable development of society. Due to the sharp increase of power load...

Problems solved by technology

[0005] 1. The distribution transformer capacity per household is a key indicator that reflects the infrastructure construction and power supply capacity of a regional distribution network. Reasonable configuration is a key measure to solve the phenomenon of power consumption being stuck and large horses and small cars. However, the facts show that there is no household distribution system in China. The corresponding technical principles of variable capacity;

[0006] 2. The increase of distribution transformer capacity per household will meet the electricity demand of users, but too high distribution transformer capacity per household will lead to light load or even no load of power equipment, resulting in waste of investment by the power sector and the country, and poor economic benefits. While satisfying the needs of users, good economic benefits must be produced

[0007] At present, the selection of distribution transformer capacity per household in my country lacks technical and economic principles, and the systematic research on distribution transformer capacity per household is still in its infancy
