[0037] In order to make the personnel in the technical field better understand the scheme, the technical solutions in the scheme embodiments will be clearly described below in combination with the drawings in the scheme embodiments. Obviously, the described embodiments are part of the embodiments of the scheme, rather than all the embodiments. Based on the embodiments in the scheme, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the scheme.

[0038] The term "comprising" and other any variants thereof in the specification and claims of the scheme and the above-mentioned drawings means "including but not limited to", which is intended to cover non-exclusive inclusion, and is not limited to the examples listed in the text. In addition, the terms "first" and "second" and the like are used to distinguish different objects, rather than to describe a specific order.

[0039] The real-time error of the gateway electric energy metering device is caused by the following reasons:

[0040] 1. The self error of the electric energy meter: the self error of the electric energy meter is mainly caused by the manufacturing process and improper use, and if it is running in the low load and low power factor load condition, the error value will also be relatively increased.

[0041] 2. The error of the mutual inductor connected with the electric energy metering device: the electric energy metering device needs to rely on the current and voltage mutual inductor for the collection of the operation data, if the mutual inductor itself has error, the collected data will also have error, which finally leads to the generation of the metering error. The error reasons of the current mutual inductor generally include: improper selection of the ratio, improper selection of the secondary capacity, improper control of the secondary load, long-term reduction of the primary current, etc. The error reasons of the voltage mutual inductor include: not setting the metering special loop, the deviation of the secondary rated power factor and the actual secondary load power factor is too large, the synthesis error, etc.

[0042] Regardless of human factors or equipment factors, the error of the gateway electric energy metering device ultimately reacts to the secondary voltage value and the current value entering the gateway table. Therefore, monitoring the secondary voltage, current and power balance can analyze the error range. The gateway electric energy metering device real-time error detection system provided in the application is based on the current gateway electric energy metering system structure, and increases the power equipment and the remote meter reading system, realizes the following two functions:

[0043] 1. Taking the bus as the reference, the power balance is analyzed. When the current direction flowing into the bus is unbalanced with the current direction flowing out of the bus, an alarm is given.

[0044] 2. Taking the average value of the secondary metering of the line single-phase voltage transformer as the reference, the accuracy of the metering voltage value is monitored in real time. When the voltage exceeds or is lower than the reference value too much, an alarm is given.

[0045] The gateway electric energy metering device real-time error detection system provided in the embodiments of the application monitors the running state of the electric energy metering device, obtains the voltage, current and other running state data and curves in the running environment through the error detection master controller and the display connected thereto, preliminarily analyzes the running error of the gateway electric energy metering device, and monitors the accuracy of the gateway metering power and the secondary voltage.
