Problems solved by technology

Due to artificial theft of electricity, failure of electric energy metering devices or out-of-tolerance measurement errors, the amount of electricity measured by the electric energy metering device will not match the actual usage, which will cause economic losses to grid companies or power generation companies and affect the fairness and fairness of measurement.
[0003] Traditional metering device management is mainly based on regular manual on-site calibration and periodic calibration of meters, which need to be carried out one by one. The workload is heavy, the work process is cumbersome and complicated, and the measurement error of the system cannot be accurately measured in real time; There are certain security risks when operating under certain circumstances, and a little carelessness will bring greater security risks to the system

Abstract

The invention provides a state discrimination method for a gateway electrical energy metering device based on the multiple agents. The method comprises the following steps: firstly, data collection is carried out; secondly, feature extraction is carried out; thirdly, state classification is carried out; fourthly, database is constructed; fifthly, analysis discrimination is carried out, namely, electrical information of a gateway electrical energy metering device is collected in real time, and on-line monitoring and state discrimination of the gateway electrical energy metering device are carried out by utilization of the multi-agent algorithm; sixthly, state feedback is carried out, namely, state discrimination of the gateway electrical energy metering device is displayed on a display screen for user reading, remote on-line monitoring and state discrimination of the gateway electrical energy metering device are achieved, and discrimination basis is provided for existence or not of metering errors. Inconvenience of on-site verification and regular replacing of a gateway metering device is avoided, economic loss of power grid companies and power plants caused by metering errors is lowered.

Description

technical field [0001] The invention relates to a monitoring method for a gate electric energy metering device, in particular to a state recognition method for a gate electric energy metering device, in particular to a state recognition method for a gate electric energy metering device based on multi-agents. Background technique [0002] The gateway metering device is an important basis for trade settlement between power generation companies and grid companies, between grid companies, and between grid companies and users. Due to reasons such as artificial theft of electricity, failure of electric energy metering devices or out-of-tolerance measurement errors, the amount of electricity measured by the electric energy metering device will not match the actual usage, which will cause economic losses to the power grid company or power generation company, and affect the fairness and fairness of measurement. [0003] Traditional metering device management is mainly based on regula...
