Metering error monitoring method for alternating current charging pile and storage medium

Abstract

The invention relates to a metering error monitoring method for an alternating current charging pile and a storage medium. The metering error monitoring method comprises the following steps: acquiring high-frequency metering point data in an electric energy meter in the charging pile; ineffective information generated by faults and violation operation in the charging pile is removed in a commemorative mode, and redundant data are removed at the same time; obtaining an electricity consumption time interval corresponding to the electricity consumption, obtaining effective time period data of each charging pile according to a preset working time, and obtaining effective data of all charging piles in a public time period at the same time; all the charging piles are divided into high-utilization-rate charging piles and low-utilization-rate charging piles according to the utilization rates, and a low-utilization-rate sample database is constructed; performing target time period data field processing on the high-utilization-rate sample database and the low-utilization-rate sample database respectively, and constructing models respectively; and solving the error of the metering point by using the constructed model. According to the invention, the operation error of the charging pile with low utilization rate in the charging station can be effectively monitored, and the problem of time and labor consumption of manual detection can be solved.

Description

technical field [0001] The invention belongs to the technical field of measurement error monitoring, and in particular relates to a measurement error monitoring method and a storage medium for an AC charging pile. Background technique [0002] In recent years, increasingly serious energy problems and environmental pollution problems have made new energy vehicles have a broad space for development. At the same time, the large-scale construction and operation of charging piles provides important support for the promotion and application of new energy vehicles. Online monitoring of the operating errors of charging piles to ensure their normal and reliable operation has also become an urgent problem to be solved in the electric vehicle industry. [0003] At present, the national metrological verification regulations have made relevant standards for the important state indicators of charging piles involving user settlement, that is, the measurement performance verification part: ...

AI Technical Summary

Problems solved by technology

However, when these standards are used in actual work, some problems will arise: the measurement performance status depends on on-site verification, and it is difficult to find abnormalities in time

However, this method is time-consuming and labor-intensive, and relies too much on the business level of professionals, so it is not suitable for the development of large-scale operation and maintenance services
