Embodiment

[0051] A theoretical line loss estimation method based on call-to-test data, such as figure 1 shown, including the following steps:

[0052] S1: Identify high-power users based on their daily power consumption.

[0053] S11: Use the power consumption information collection system of the distribution network to obtain the daily power consumption data of users and station areas.

[0054] The daily electricity consumption data of the station area and the users in the station area are obtained from the electricity consumption information collection system of the distribution network, and the data source is simple and reliable.

[0055] S12: Determine whether the daily power consumption of the user is greater than 30% of the total power consumption of the station area, if yes, go to step S13; if not, end.

[0056] S13: Determine whether the user's daily power consumption is greater than 100 kWh, if yes, determine that the user is a large power user, and enter step S2; if not, end...

Abstract

The invention discloses a theoretical line loss estimation method based on interrogation data. The method aims to solve the problems that a theoretical line loss calculation method in the prior art needs a large amount of data, has high data requirements, is complex and is not suitable for a production environment. The method comprises the following steps: S1, identifying a large-power user according to the daily power consumption of the user; s2, load interrogation is carried out, and power utilization data of a large-electric-quantity user and a terminal are obtained; and S3, calculating a theoretical line loss value according to the interrogation data. The theoretical line loss value is estimated simply and quickly with less data required by calculation, so that workers can know the line loss condition and the change trend preliminarily and conveniently, and the method is suitable for the production environment.

Description

technical field [0001] The invention relates to the field of line loss estimation, in particular to a method for estimating theoretical line loss based on survey data. Background technique [0002] Line loss refers to the amount of electricity lost in a line. Theoretical line loss refers to the line loss value calculated on the theoretical level, but due to other factors in actual production, the statistical line loss is greater than the theoretical line loss. Theoretical line loss calculation plays an important role in measuring the economic operation of the power grid, evaluating the rationality of the grid structure and layout, identifying weak links in the power grid, formulating loss reduction measures, and reasonably issuing line loss assessment indicators. important content in loss management. At present, many experts have carried out in-depth research on theoretical line loss, and proposed line loss calculation methods including power flow method and equivalent cal...
