Description

A kind of a plurality of looped networks station system
Technical field
The utility model relates to a kind of electrical power distribution automatization system, relates in particular to a kind of a plurality of looped networks station system.
Background technology
In electrical power distribution automatization system, the extraction problem of control power supply and working power is a difficult point.Comparatively current at present way is the control power supply of switch and the station electricity consumption that working power is all taken from this looped network station in Distributing Terminal Assembly and the station.Fig. 1 is the structure (becoming the looped network of forming with European case is example) of traditional power distribution automation dicyclo website, comprise #1 looped network station 111 and #2 looped network station 112, #1 looped network station 111 comprises #1 distribution transformer 15, #1 stand electricity consumption 17, higher level transformer station outlet circuit breaker 11 and on-load switch 12; #2 looped network station 112 comprises #2 distribution transformer 16, #2 stand electricity consumption 18, higher level transformer station outlet circuit breaker 113 and on-load switch 14.The station commonly used electricity consumption at #1 looped network station 111 is provided by lead 19 by the self loop website, and the standby station electricity consumption is provided by lead 110 by #2 looped network station.
When 13 places broke down, higher level transformer station outlet circuit breaker 11 at first tripped, because of on-load switch 14 in the separating brake position, #1 distribution transformer 15 dead electricity, 19 also dead electricity.At this moment, have two incidents to take place simultaneously: (1) because of 19 dead electricity, and #1 station electricity consumption 17 device action of autotomying switches to the station electricity consumption from 110 of #2 distribution transformer, and required time is about 1 second.In this 1 second, the electricity consumption of standing is power failure state always.(2) break down after, power distribution automation intelligent decision program start, after higher level transformer station outlet circuit breaker 11 tripping operation, remote control on-load switch 12 tripping operations immediately are with isolated fault.And this moment, #1 station electricity consumption 17 is being switched, cause provides the control power supply of on-load switch 12 tripping operations from #1 station electricity consumption 17, therefore, if the trip command that the intelligent decision program is issued on-load switch 12 just in time is in 1 second that #1 station electricity consumption 17 switches, on-load switch 12 can or not trip because of there being the control power supply, thereby cause the Fault Isolation failure, and #1 distribution transformer 15 also can't restore electricity from #2 looped network station 112 (because of on-load switch 12 does not trip, on-load switch 14 can not close a floodgate, otherwise on-load switch 14 will close in 13 place's faults, cause bigger accident).
The problem that above-mentioned dicyclo website exists equally also is present in a plurality of looped networks station, and therefore, the continuity of station electricity consumption when traditional station electricity consumption (band is autotomyed) structure can not guarantee to break down can not satisfy the needs of power distribution automation fully.
Summary of the invention
The purpose of this utility model provides a kind of a plurality of looped networks station system exactly in order to address the above problem.
The purpose of this utility model is achieved in that a kind of a plurality of looped networks station system, comprise several looped network stations, described looped network station comprises distribution transformer, stand electricity consumption and on-load switch, on-load switch links to each other by lead with distribution transformer, simultaneously, link to each other by lead between each looped network station, and this lead is provided with on-load switch, it is characterized in that:
The distribution transformer at a looped network station in the described system in the station commonly used electricity consumption at arbitrary looped network station and all the other looped network stations links to each other by lead, promptly provides station electricity consumption commonly used by the latter for the former;
The distribution transformer of the standby station electricity consumption at arbitrary looped network station and this looped network station self links to each other by lead in the described system, promptly by this looped network station for the standby station electricity consumption is provided self.
The quantity at described several looped network stations can be three or four.
The utility model makes it have following advantage and characteristics owing to adopted above technical scheme:
1, the continuity of station electricity consumption in the time of can guaranteeing to break down;
2, send the success of electricity for power distribution automation fault judgement, isolation and recovery powerful guarantee is provided.
Description of drawings
Fig. 1 is the structural representation of traditional power distribution automation dicyclo website;
Fig. 2 is the structural representation of a plurality of looped networks of the utility model station system.
Embodiment
Referring to Fig. 2, Fig. 2 is the structural representation of a plurality of looped networks of the utility model station system.This system comprises four looped network stations, is respectively #1 looped network station 21, #2 looped network station 22, #3 looped network station 23 and #4 looped network station 24.
Described #1 looped network station 21 comprises higher level transformer station outlet circuit breaker 25, #1 distribution transformer 211, #1 station electricity consumption 212 and on-load switch 214, links to each other by lead each other;
Described #2 looped network station 22 comprises #2 distribution transformer 221, #2 station electricity consumption 222 and on-load switch 223, links to each other by lead each other;
Described #3 looped network station 23 comprises #3 distribution transformer 231, #3 station electricity consumption 232 and on-load switch 233, links to each other by lead each other;
Described #4 looped network station 24 comprises higher level transformer station outlet circuit breaker 26, #4 distribution transformer 241, #4 station electricity consumption 242 and on-load switch 243, links to each other by lead each other.
It is characterized in that:
The station commonly used electricity consumption at described #1 looped network station 21 is provided by lead 234 by #3 looped network station 23, and the standby station electricity consumption self is provided by lead 215 by #1 looped network station 21;
The station commonly used electricity consumption at described #2 looped network station 22 is provided by lead 225 by #4 looped network station 24, and the standby station electricity consumption self is provided by lead 224 by #2 looped network station 22;
