Problems solved by technology

During carrier communication, the carrier signal can reach the adjacent station area through the neutral line, and the power supply domain of the station area is different from the communication domain of the carrier. Therefore, it will be misjudged to determine the ownership of the smart electric energy meter only by the success of the carrier communication.

Embodiment Construction

[0010] 1. Basic conditions:

[0011] 07 Standard energy meters support power-off records, which can record the power-off and power-on time of the energy meter;

[0012] 07 standard energy meters all support the clock overshoot of the energy meter, which can judge the clock error of the energy meter.

[0013] Second, the basic principle:

[0014] Combined with the clock error of the energy meter, the more accurate power-off time and power-on time of the energy meter can be calculated;

[0015] By comparing the power-off time and power-on time of the transformer end and the energy meter end, the transformer ownership of the energy meter can be effectively judged.

[0016] 3. Data acquisition:

[0017] Accurate power-off and power-on time at the transformer side;

[0018] Power-off and power-on time of the electric energy meter;

[0019] The clock error of the energy meter terminal.

[0020] 4. Data acquisition method:

[0021] Accurate power-off and power-up times at the ...

Abstract

The invention discloses a method for judging the affiliation of a transformer area meter by utilizing power-off and power-on records of an intelligent meter. The invention discloses a method for effectively and automatically judging transformer attribution of an electric energy meter by comparing power-off time and power-on time of a transformer end and an electric energy meter end. Relatively accurate power-off time and power-on time of the electric energy meter can be calculated in combination with the clock error of the electric energy meter; the transformer attribution of the electric energy meter can be effectively judged by comparing the power-off time and the power-on time of the transformer end and the electric energy meter end.

Description

technical field [0001] This method effectively solves the problem of automatic division of station area load that has plagued power supply enterprises for a long time. It changes the traditional manual judgment method and provides a more reliable criterion. Through the use of this method, it solves (1) realizes the automation of station area division, saves labor and instrument costs for investigation, and improves operating efficiency; (2) provides reliable criteria and improves management level. Background technique [0002] The construction of electricity consumption information collection system (hereinafter referred to as collection system) has now entered the stage of deepening application. Among them, applications such as line loss analysis in the low-voltage station area, remote fee control, remote recharge, and clock calibration all require a clear and clear smart meter area attribution, that is, the low-voltage station area must have correct load division.
