Asynchronous load acquisition modification method for partial electricity utilization

Abstract

The invention discloses an asynchronous load acquisition modification method for partial electricity utilization, which relates to the technical field of electric power, and aims at solving the technical problem of reducing the acquisition time error of asynchronous data acquisition. The method comprises the following steps of: obtaining an electricity utilization wire-outgoing load set and electricity utilization load data of an energy consumption monitoring system, and dividing the obtained electricity utilization load data into two types at first; then calculating a current difference and an active power difference, and then calculating a modification factor; then performing corresponding modification on the three-phase current, active power and reactive power of each wire-outgoing load by virtue of the modification factor. The method provided by the invention is capable of improving the accuracy of an energy consumption monitoring analysis result.

Description

technical field [0001] The invention relates to electric power technology, in particular to a technology of a load correction method for sub-item electricity consumption asynchronously collected. Background technique [0002] The power system is equipped with an energy consumption monitoring system for monitoring the electricity consumption status of power users. Power companies can monitor power users’ sub-item energy consumption through the energy consumption monitoring system.

Problems solved by technology

However, in the process of data correction, since the data collection time of various metering devices is not completely synchronized, there is a large collection time error between the data collected at the same collection point, which may bring big differences to the results of energy consumption monitoring and analysis. Large deviations may even lead to errors in energy-saving analysis reports, reduce the effect of energy-saving implementation, and cause large energy waste
