Abstract

According to the electric energy metering device verification equipment start-stop parameter early warning method and system provided by the invention, the real-time start-stop parameter of the verification equipment is obtained when the verification equipment is switched in the operation state, and whether the verification equipment is in the alarm state is determined according to the real-time start-stop parameter of the verification equipment, when the verification equipment is in an alarm state, an alarm signal can be sent out, the parameter condition of the verification equipment when the verification equipment is input or cut out is fed back to an operator or a control system in time, and the information that the starting and stopping parameters of the verification equipment are abnormal is provided for the operator or the control system of the verification equipment in time, an operator or a control system can conveniently make adjustment in time, it can be avoided that errors are possibly introduced to the verification result of the electric energy metering device when verification equipment is input or cut out in the state that the verification equipment does not meet the conditions, and the verification accuracy is improved.

Description

technical field

[0001] The invention relates to the technical field of equipment detection, in particular to a method and system for early warning of start-stop parameters of electric energy metering device verification equipment. Background technique

[0002] Electric energy metering device, as a device for measuring electricity in the power system, is an important metering device in the process of electric power creation, transmission, and application. With the development of computer technology and automatic control technology, the automatic verification process of electric energy metering devices tends to change from traditional manual control to a fully automated process, which can greatly improve the verification production efficiency, reduce the verification production cost, and reduce the probability of accidents . Among them, the verification equipment of the electric energy metering device is a collection of a series of devices that can provide standard source sig...
