Embodiment

[0046] This embodiment provides a method for real-time online calculation and analysis of power loss for distribution, which is characterized in that: the method for real-time online calculation and analysis of power loss for distribution includes:

[0047] Copy power: Calculate the copy power of the main metering point (no superior metering point) according to the meter difference × magnification between the collected hourly reading and the previous full-time reading;

[0048] Quantitative power: Quantitative power = quantitative value × number of operating days / 30 / 24

[0049] Note: Number of days of operation = 1

[0050] Daily agreement electricity: daily agreement electricity=quantitative value×running days / 24

[0051] Note: Number of days of operation = 1

[0052] Variable loss power: For customers whose metering method is: high supply and low meter, and the high-voltage side has not installed an assessment meter, since the collected low-voltage side data does not inclu...

Abstract

According to an online real-time calculation and analysis method of equipped wire loss, read electric quantity calculation and transformer power loss electric quantity calculation are performed, wherein an instrument error between an obtained collected integral point display number and a last integral point display number is multiplied by a multiplying power, and the read electric quantity of a main metering point is calculated; for electricity customers with a metering mode of high-voltage-side power supplying and low-voltage-side metering and without an examination meter on the high voltage side, when integral point electric quantity is calculated, the integral point transformer power loss electric quantity of a transformer is calculated according to user profiles and the type of the transformer based on the integral point read electric quantity; the read electric quantity of the main metering point is calculated according to the display number difference between an obtained collected daily zero point display number and a zero point display number of the last day is multiplied by the multiplying power. The online real-time calculation and analysis method has the advantages that the function of copying and reading data in real time is achieved, and the function becomes an important means for wire loss monitoring and analysis. Important analysis data such as instantaneous magnitude and alarming information are obtained, all system module data are integrated, high-speed calculation of mass data can be conducted independently, and independent marketing wire loss application of the function of an existing system is not affected.

Description

technical field [0001] The invention relates to the field of line loss in the power system industry, in particular to a method for real-time on-line calculation and analysis of distribution line loss. Background technique [0002] At present, power grid resources such as substations, switches, lines, and station areas and their collected data and monitoring data are placed in the gateway collection system, and the electricity consumption information of electricity customers is placed in the electricity collection application, while customer files and the relationship between lines and metering points And the user's billing power is placed in the marketing business application, and each system calculates the line loss according to its own data, which fails to realize the calculation, statistics and analysis of the entire network line loss from the substation to the user. Contents of the invention [0003] The object of the present invention is to accurately measure the loss...
