Abstract
The utility model relates to a cable ring network structure of a power distribution network, which comprises transformer stations, K type stations, P type stations and WX type stations. Adjacent transformer stations are connected through one K type station. The K type station is further connected with P type stations. Each transformer station is respectively connected with one more K type station. The K type station located between adjacent transformer stations is also connected with a single-ring network. Compared with the prior art, the cable ring network structure of the power distribution network has the advantages of power consumption reliability increase, etc.
Description
Technical field
The utility model relates to a kind of distribution system, especially relates to a kind of cable ring-system structure of power distribution network.
Background technology
The general wiring complexity of distribution system, number of devices is various, amount of information is huge, exist certain related between each device parameter and the state, corresponding data and operate closely relatedly, the forecast assessment of finishing distribution system user power supply reliability by craft is very difficult.Develop software systems for forecast assessment even can utilize computer technology, but if the software systems of exploitation only are off-lines, then the user still needs to utilize graphical interfaces manually to draw electric hookup in advance on computers, parameter and the state information of input all devices, and when electric network composition changes, power system operating mode or Plant maintenance plan change and when having new equipment to drop into, also need the user artificially to revise winding diagram and device parameter, workload is very big, simultaneously also make mistakes the situation that the result will cause the real work personnel that the off-line forecast assessment software systems of developing are given it up easily.
The network configuration of power distribution network is the basis of its reliability level, brief flexible net topology can ensure user's dwindling of scope that have a power failure, namely under failure condition, non-faulted line segment load is changeed band, arrange in advance non-pre-arrangement line segment load to be changeed band under the power-off condition at equipment.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of cable ring-system structure that improves the power distribution network of electricity consumption reliability for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of cable ring-system structure of power distribution network, it is characterized in that, comprise transformer station, K type station, P type station and WX type station, connect by K type station between a plurality of transformer stations are adjacent, and this K type station connects P type station, each transformer station connects K type station respectively, and the K type station between the adjacent substations connects Single-ring network.
Described Single-ring network is by being connected two P type station, band WX type stations, P type station under the K type station separately, and the band WX type station, P type station that connects two K type stations is respectively formed.
Band WX type station, described P type station refers to that a P type station connects the WX type station of four circulation series connection; Band WX type station, described P type station refers to two the WX type stations in parallel behind another P type station of connecting, P type station, and two WX type stations interconnect.
Described transformer station connects the WX type station that K type station also can connect one six circulation series connection separately.
Compared with prior art, the utility model distribution wiring pattern is reasonable, cable system adopts the radial pattern wiring pattern at band P type station, K type station or band WX type station, K type station substantially, can ensure user's dwindling of scope that have a power failure with brief flexible net topology, has improved the reliability of electricity consumption.
Description of drawings
Fig. 1 is the structural representation of utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of cable ring-system structure of power distribution network, comprise transformer station, K type station, P type station and WX type station, connect by K type station between a plurality of transformer stations are adjacent, and this K type station connects P type station, each transformer station connects K type station respectively, and the K type station between the adjacent substations connects Single-ring network.
Described Single-ring network is by being connected two P type station, band WX type stations, P type station under the K type station separately, and the band WX type station, P type station that connects two K type stations is respectively formed.Band WX type station, described P type station refers to that a P type station connects the WX type station of four circulation series connection; Band WX type station, described P type station refers to two the WX type stations in parallel behind another P type station of connecting, P type station, and two WX type stations interconnect.
Described transformer station connects the WX type station that K type station also can connect one six circulation series connection separately.
As shown in Figure 1, be example with two transformer stations, be connected two P type stations 6 of K type station a3, K type station a3 series connection between the a1 of transformer station and the b2 of transformer station, the a1 of transformer station connects a K type station b4 separately, the b2 of transformer station connects a K type station c5 separately, K type station b4 is connected Single-ring network with K type station c5, that is: the K type station b4 P type station 6 of connecting, this P type station 6 connects the WX type station 7 of 4 circulation series connection, K type station c5 three the P type stations 6 of connecting, K type station b4 is connected a P type station 6 simultaneously with K type station c5, and this P type station connects the WX type station 7 that two circulations are connected after connecting another P type station.
Wherein K type station c5 also connects the WX type station 7 of 6 circulation series connection.
