Step S20 is according to described subscriber profile data, Unit account of plant data and power network topology information architecture transformer station-circuit-transformer-user's corresponding relation.
Concrete, the basic datas such as the subscriber profile data that utilization is obtained, Unit account of plant data build transformer station-circuit-transformer-user's corresponding relation on the Distribution power network GIS figure according to power network topology.
Step S30 obtains faulty equipment information and selectes power failure range according to described faulty equipment information and described power network topology information.
Concrete, transfer the mode of lock, wireline inspection (as line data-logging) to find out the equipment that produces fault, the then relevant information of typing faulty equipment according to switch; For example, the information such as faulty equipment and device type thereof, in power distribution network positional information etc.
After obtaining the relevant information of faulty equipment, be directed to zone and the circuit at faulty equipment place, be selected in the power failure range when faulty equipment is overhauled; Wherein, selected power failure range is in conjunction with the Distribution power network GIS figure, and selected power-off switch, divide power supply interrupted district by power-off switch on the GIS figure, determines power failure range by power-off switch.
As an embodiment, the method for selected power failure range can comprise as follows:
(1) be power failure range by the zone between selected former and later two power-off switches of faulty equipment of direction of current; Concrete, according to sense of current, the zone before and after faulty equipment between selected two power-off switches is power failure range, when formulating the power failure scheme; For example, selected power-off switch A presses direction of current to power-off switch B(, and the A switch is before the B switch), the zone between switch A, B is power failure range.
(2) press the front single power-off switch of the selected faulty equipment of direction of current and down partly be power failure range; Generally, can't turn involved area under electric power thus supplied, selected single power-off switch before faulty equipment, by single power-off switch power failure range, the following part of switch is all as power failure range.For example, selected power-off switch A(is with direction of current), the following All Ranges of switch A is power failure range
Step S40 carries out power network topology according to described corresponding relation to selected power failure range and follows the trail of, and determines the customer interrupted in this power failure range;
Particularly, call the Distribution power network GIS service, carrying out power failure range follows the trail of, take Distribution power network GIS topological structure of electric structure as the basis, press direction of current, selected power failure range is carried out follow-up analysis, in conjunction with transformer station-circuit-transformer-user's corresponding relation, obtain the customer interrupted information of selected power failure range impact.
In one embodiment, the process of step 40 comprises the steps:
