Embodiment

[0021] In an embodiment, a method for controlling line loss in a distribution station area under seasonal loads includes the following steps:

[0022] (1) Grouping of electricity load characteristics: The single-phase power supply users in the station area are divided into commercial electricity load and residential electricity load according to the nature of electricity load.

[0023] (2) Three-phase grouping: Divide the total quarterly electricity consumption load of residents in the station area by the average value of Sande, and divide the electricity consumption load of residents in the station area into three groups according to the average value. The difference between the values ​​is within 10%; then the three groups of residential electricity loads are divided into A-phase power supply, B-phase power supply, and C-phase power supply;

[0024] Divide the total quarterly commercial electricity load in the station area by the Santo average value, and divide the residenti...

Abstract

The invention relates to a line loss control method for a power distribution area under seasonal load. The line loss control method comprises the following steps of (1) grouping the electrical load characteristics, namely dividing the single-phase power supply users in the area into the commercial electrical load and the residential electrical load according to the electrical load characteristics;(2) grouping three phases, namely dividing the residential seasonal total electrical load in the area by three to obtain an average value, dividing the residential electricity loads in the area intothree groups according to the average value, wherein the difference between the total seasonal electricity load of each group and the average value is within 10%; and then dividing the three groups ofresidential electricity loads into A-phase power supply, B-phase power supply and C-phase power supply respectively. According to the present invention, the line loss under the condition of seasonalload outburst can be effectively reduced.

Description

technical field [0001] The invention relates to a method for controlling line loss in a distribution station area under seasonal load. Background technique [0002] The level of line loss rate can effectively reflect the problems of power grid structure or enterprise management. Under the background of State Grid Corporation of China's requirements for in-depth management of line loss, how to manage line loss in low-voltage station areas time-saving and efficiently has become a major issue for various municipalities. The primary goal of the company's marketing department, especially after the implementation of the rural power network transformation, companies in various cities have paid more and more attention to low-voltage line loss, and have also studied various methods to reduce low-voltage line loss [1]-[3]. According to relevant literature reports, when the three-phase load of the low-voltage power grid is unbalanced, the line loss rate can reach up to 6-9 times that o...
