Problems solved by technology

[0002] With the continuous improvement of the informatization level of the marketing system of power companies and the continuous introduction of new requirements for the deepening and application of power consumption information collection systems, in order to better serve the majority of power users, power companies need to collect single-phase meters of users in low-voltage distribution stations. Phase information, in the prior art, the phase detection is generally carried out through power failure, but this method will affect the daily life of users, and at the same time, processing each distribution station area separately will also cause waste of manpower and material resources

Embodiment 1

[0051] A large data identification method for low-voltage distribution box user phases based on load mutation synchronization, such as Figure 4 As shown, the specific steps are as follows:

[0052] S1: The power consumption information collector periodically samples and saves the three-phase current values; the cycle is 1 second;

[0053] S2: During the operation of the power consumption information collector, if the communication message of "synchronous inspection of current mutation" uploaded by the single-phase electric energy meter is received, the three-phase current change values ​​are calculated respectively;

[0054] S3: Analyze the three-phase current change values ​​of phase A, phase B and phase C to obtain phase information of the single-phase electric energy meter.

Embodiment 2

[0056] On the basis of Embodiment 1, the method of uploading the "synchronous inspection of current mutation" communication message by the single-phase electric energy meter is as follows: Figure 5 As shown, that is, the working process of the single-phase electric energy meter, the specific steps are as follows:

[0057] 21) After the single-phase electric energy meter AdrX is powered on and running, the single-phase current value is periodically sampled and saved; the cycle is 1 second;

[0058]22) Calculate the current change value Iscd and the current change percentage Iscp, and judge whether the current change value Iscd and the current change percentage Iscp meet the preset conditions. "Communication message.

[0059] As a preferred embodiment, the method for calculating the current change value Iscd and the current change percentage Iscp is as follows:

[0060] Current change value Iscd=|Icur–Ipre|;

[0061] Current change percentage Iscp=(Iscd / Ipre)*100%;

Abstract

The invention discloses a large data identification method for the user phase of a low-voltage power distribution box based on load mutation synchronization. First, the electricity information collector periodically samples and saves the three-phase current values; The "synchronous inspection of current mutation" communication message uploaded by the phase watt-hour meter calculates the three-phase current change value respectively; analyzes the three-phase current change values ​​of A phase, B phase and C phase to obtain the phase information of the single-phase watt-hour meter. The invention can realize the phase information identification of the single-phase meter of the user in the low-voltage distribution station area under the premise of no power failure.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a large data identification method for user phases of low-voltage distribution boxes based on load mutation synchronization. Background technique [0002] With the continuous improvement of the informatization level of the marketing system of power companies and the continuous introduction of new requirements for the deepening and application of power consumption information collection systems, in order to better serve the majority of power users, power companies need to collect single-phase meters of users in low-voltage distribution stations. For phase information, in the prior art, phase detection is generally carried out through power failure, but this method will affect the daily life of users, and at the same time, processing each distribution station area separately will also cause waste of manpower and material resources.
