Embodiment Construction
[0023] The technical scheme of the present invention is described further below:
[0024] The low-voltage branch topology identification method in the carrier station area, the steps are as follows:
[0025] Step 1, identify the station area;
[0026] Step 2, performing automatic phase identification;
[0027] Step 3, identify the relationship between the household meter and the meter box and distinguish the power supply;
[0028] Step 4: Obtain the topological relationship among branches, meter boxes, and household meters.
[0029] The identification of the station area adopts the method of power outage reporting or zero-crossing identification or feature comparison and integrates independent multi-dimensional data to automatically identify and iteratively optimize the electric energy meters inside and outside the station area.
[0030] Station area identification is divided into CCO centralized mode and STA distributed mode.
[0031] Such as figure 1 As shown, in the CC...
