Detailed Description
The method and system for synchronizing distribution system events based on hierarchical distribution of the present invention are described in detail below with reference to the accompanying drawings.
Example 1
This embodiment illustrates a power distribution system event synchronization method based on hierarchical distribution, as illustrated in fig. 1. The power distribution system event comprises one of power distribution faults, power distribution abnormality and data monitoring, and the power distribution system event in the embodiment is power distribution fault assignment.
The hierarchical-based power distribution system generally comprises a plurality of power distribution devices in communication connection in the hierarchical distribution of the power distribution system, wherein each power distribution device at least comprises a plurality of bottom-layer power distribution terminals, generally a power distribution cabinet or a power distribution box, the bottom-layer power distribution terminals of the embodiment are power distribution cabinets, and an intermediate layer in communication connection with the plurality of bottom-layer power distribution terminals, the intermediate layer of the embodiment is a central collector, has certain operation capability, and can store a certain amount of data.
As shown in fig. 1, the method for synchronizing distribution system events based on hierarchical distribution provided by the embodiment of the invention comprises the following steps:
s101, resetting a failed middle layer in communication connection with a plurality of bottom layer distribution terminals in a plurality of distribution devices in communication connection in the distribution system hierarchical distribution;
s102, acquiring the reset middle layer event number N0 and the plurality of bottom layer power distribution terminal event numbers N1;
s103, synchronizing the middle layer event number N0 with the plurality of bottom layer power distribution terminal event numbers N1 such that n0=n1;
s104, acquiring the subsequent event numbers N1 'of the plurality of bottom-layer power distribution terminals, and calculating a difference value M between the subsequent event numbers N1' of the plurality of bottom-layer power distribution terminals and the synchronized event number N0 of the middle layer;
s105, when the difference value M >0, the M events are called.
Specifically, when a failure of the concentrator in the power distribution system is detected, it is necessary to reset the concentrator to ensure that the whole power distribution system operates normally. Reset generally refers to replacing or formatting the center concentrator. And after the central concentrator is reset, acquiring the reset central concentrator event number N0 and the event number N1 of the bottom-layer power distribution cabinet. The event number N0 of the middle collector is forced to be synchronous with the event number N1 of the bottom-layer power distribution cabinet, namely N0=N1, so that the event number of the middle collector after reset is the same as the event number of the bottom-layer power distribution cabinet before reset. Because the event number of the bottom power distribution cabinet can be collected in real time and stored in the central collector when the central collector runs, the event number of the central collector is reset to zero after the central collector is reset, and the purpose of synchronization is to recover the event number stored before the central collector fails. The method for synchronizing can send out a command by the central collector, collect the event number of the bottom-layer power distribution cabinet and enable the event number of the central collector to be consistent with the event number of the bottom-layer power distribution cabinet. After synchronization is completed, the central collector sends an instruction to the bottom-layer power distribution cabinet, the event number N1 'of the subsequent bottom-layer power distribution cabinet is obtained, the difference value M between the N1' and the synchronized N0 is calculated, and when M >0, the fact that the obtained event number of the subsequent bottom-layer power distribution cabinet is more than that of the central collector after synchronization is described, and the number of M events needs to be called. The calling refers to the fact that a central collector initiates a command for acquiring the number of events of the bottom-layer power distribution cabinet and collects the number of events in the power distribution cabinet.
According to the distribution system event synchronization method based on the hierarchical distribution, when the middle collector fails for various reasons or needs to be formatted and reset in the two-hierarchy distribution system, the recorded event number of the bottom-layer distribution cabinet or the distribution box and the middle collector is re-synchronized, so that the event number of the middle collector after reset in the subsequent bottom-layer distribution cabinet or the distribution box is conveniently and repeatedly counted, the middle collector is ensured to not repeatedly collect the distribution system event, the middle collector resource is saved, and the electric power operation safety is ensured.

s202, acquiring the number N0 of events in the middle layer after reset and the number N2 of events reported to the top server by the middle layer;
s203, synchronizing the middle layer event number N0 with the event number N2 reported by the top layer server, so that N0=N2;
s204, acquiring the subsequent event numbers N1 'of the plurality of bottom-layer power distribution terminals, and calculating a difference M between the subsequent event numbers N1' of the plurality of bottom-layer power distribution terminals and the synchronized event number N0 of the middle layer;
s205, when the difference value M >0, the M events are called.
Specifically, S201 in the second embodiment is the same as S101 in the first embodiment, and will not be described here again. After the central server is reset, the number N0 of events of the central layer after reset and the number N2 of events reported to the top server by the central layer during reset are obtained. And (3) forcibly synchronizing the event number N0 of the middle layer with the event number N2 reported to the top server by the middle layer, namely, N0=N2, so that the event number of the middle collector after reset is the same as the event number reported to the top server before reset. After resetting the concentrator in a three-tier power distribution system, the number of concentrator events is zero, so the purpose of synchronization is to recover the number of events stored before the concentrator failed. After synchronization is completed, the central collector sends an instruction to the bottom-layer power distribution cabinet, the event number N1 'of the subsequent bottom-layer power distribution cabinet is obtained, the difference value M between the N1' and the synchronized N0 is calculated, and when M >0, the fact that the obtained event number of the subsequent bottom-layer power distribution cabinet is more than that of the central collector after synchronization is described, and the number of M events needs to be called.
