AI Technical Summary

Technical Problem

Existing technologies suffer from incomplete and inaccurate parameters when calculating reasonable ranges for line loss rates. They are also complex in calculation methods, cannot be applied to both lines and transformer substations simultaneously, and traditional algorithms consume a lot of computing resources, making it difficult to meet the management needs of power grid companies.

Method used

By acquiring monthly line loss rate data for lines and transformer substations within the power grid zone, data cleaning and outlier removal are performed. The average line loss rate and outlier rate are calculated to determine the reasonable range coefficient for the line loss rate. The rationality of the theoretical line loss rate is evaluated by using a simple percentage calculation method to avoid complex clustering and decision tree algorithms.

Benefits of technology

It enables direct assessment of the reasonable range of line loss rates for lines and transformer substations, improves the management efficiency of power grid companies, simplifies the calculation process, reduces the demand for computing resources, and enhances the usability and accuracy of the assessment.

Abstract

The application discloses a kind of theoretical line loss rate evaluation method and system, method includes obtaining the initial monthly line loss rate data and monthly line loss rate abnormal rate data of several months of all line stations in power grid partition, line station includes line and area;Each initial monthly line loss rate data is cleaned up and abnormal data is rejected, to obtain the first monthly line loss rate data;According to the first monthly line loss rate data and preset rejection rule, calculate monthly line loss rate average, judge whether monthly line loss rate average satisfies first preset condition, if satisfy, then according to monthly line loss rate average, determine line loss rate reasonable interval, if not satisfy, then calculate line loss rate reasonable interval coefficient, and according to line loss rate reasonable interval coefficient and monthly line loss rate average, calculate line loss rate reasonable interval;According to line loss rate reasonable interval, evaluate the rationality of theoretical line loss rate calculation value.This embodiment calculates the line loss rate reasonable interval of line and area simultaneously, effectively evaluates theoretical line loss rate, improves power grid company management efficiency.
