Abstract

The invention discloses a method for finely and accurately comparing line losses based on a smart-grid technology, and belongs to the field of measurement. The method comprises electric quantity settlement of a user and electricity consumption information acquisition, and is characterized by comprising the following steps of: constructing a unified distributed analysis system for finely and accurately comparing the line losses based on .NET Remoting software system architecture; adopting corresponding electric quantity settlement and electricity consumption information acquisition modes aiming at different types of users to form line loss statistic subsystems aiming at the different types of users; performing data or information transmission between each line loss statistic subsystem and a unified line loss management application platform by adopting a shared database interface form, and a mode of directly importing data based on an integrated data processing (IDP) data access interface of Web Service or an Excel file; realizing acquisition, conversion, cleaning and warehousing of remote heterogeneous data, and establishing a data dynamic seamless interconnection mechanism and an information real-time fast interaction mechanism; and finally realizing the fine comparison of the line losses to ensure that user side information is visible and controllable. The method can be widely used in the field of operation / management of an electric power system.

Description

technical field

[0001] The invention belongs to the field of measurement, in particular to a line loss measurement method for electric energy measurement. Background technique

[0002] In the process of transmission and distribution (transformation) of electric energy, the power loss, electric energy loss and other losses generated by each component in the power network are collectively referred to as line loss (power supply loss), referred to as line loss.

[0003] For the urban power supply department, the line loss usually includes all the electric energy loss from the main transformer of the substation to the electric energy meter of the user.

[0004] Line loss electricity cannot be directly measured, it is calculated by subtracting power supply and electricity sales.

[0005] The percentage of line loss power to power supply is called line loss rate, or line loss rate for short.

[0006] Line loss rate is an important economic index of power supply enterprises, which...
