Each backup auto-activating device of the present utility model is without the difference of main website, substation, each substation is main website, with the mode communication contact of cascade dual-ring network (two networks are independent) between each station, two any one networks of cascade loop network are normal, region prepared auto restart can normally work, substantially reduce the impact of Network Abnormal on the operation of region backup auto-activating device, region prepared auto restart logic identifies on the spot, realize the trip avoidance function of self, do not affect the tripping operation at other stations, avoid false tripping, by the closing function at other stations of real-time performance.
Cascade dual-ring network is optical fiber cascade network, exchanges a large amount of data by optical fiber.
Backup auto-activating device comprises two independently communication interfaces, is respectively used to connection two cascade loop network; The communication direction of two communication interfaces is contrary.
Backup auto-activating device is incorporated to chain type electrical network after connecting the circuit breaker of the transformer station left and right sides in chain type electrical network.
Compared with prior art, the utility model comprises following beneficial effect:
The utility model adopts full main website cascade prepared auto restart pattern, and this pattern is simple and directly perceived, explicit physical meaning; Comparatively main website-substation pattern, the utility model not only reduces the use of equipment, saves Financial cost, adopts the mode of dual-ring network cascaded communication, also reduce the probability because network communication abnormal region prepared auto restart cannot normally work, improve the stability of operation of power networks.
Accompanying drawing explanation
The structural representation of Fig. 1 chain type electrical network;
Fig. 2 is the structural representation of the utility model chain type electrical network spare power automatic switching system.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The chain network in accompanying drawing 1 is shown in by the structure chart of chain type electrical network.Be power station at the two ends of network, centre is chain type electrical network.As shown in Figure 2; the utility model adopts the structure of full main website cascade mode; namely at two power stations; and a region backup auto-activating device is all installed by middle each transformer station, and (backup auto-activating device full name computer line backup power automatic switching protection device is a kind of protective device, has strong interference immunity, the advantage such as reliable and stable, easy to use.), device independently runs and the circuit breaker of the only required control of control itself, information interaction between backup auto-activating device is realized by optical fiber cascade network, and adopt dual-ring network pattern, as long as have one in two cascade ring networks normally, region prepared auto restart just can normally realize prepared auto restart function.
As shown in Figure 2, chain type electrical network spare power automatic switching system, comprises several backup auto-activating devices, and power station and the middle transformer station of chain network all arrange backup auto-activating device, are connected between described backup auto-activating device by cascade dual-ring network; Cascade dual-ring network comprises two cascade loop network, and independently ring week connects all backup auto-activating devices to described two cascade loop network.
Each backup auto-activating device of the present utility model is without the difference of main website, substation, each substation is main website, with the mode communication contact of cascade dual-ring network (two networks are independent) between each station, two any one networks of cascade loop network are normal, region prepared auto restart can normally work, substantially reduce the impact of Network Abnormal on the operation of region backup auto-activating device, region prepared auto restart logic identifies on the spot, realize the trip avoidance function of self, do not affect the tripping operation at other stations, avoid false tripping, by the closing function at other stations of real-time performance.
Cascade dual-ring network is optical fiber cascade network, exchanges a large amount of data by optical fiber.
Backup auto-activating device comprises two independently communication interfaces, is respectively used to connection two cascade loop network.
Backup auto-activating device is incorporated to chain type electrical network after connecting the circuit breaker of the transformer station left and right sides in chain type electrical network.As in Fig. 1, backup auto-activating device between circuit breaker C1, C2, between D1, D2 ... between N1, N2, C1, C2, D1, D2, N1, N2 are circuit breaker.
