Detailed Description
The method and system for synchronizing events of a power distribution system based on hierarchical distribution according to the present invention are described in detail below with reference to the accompanying drawings.
Example one
The present embodiment takes the example shown in fig. 1 to illustrate the distribution system event synchronization method based on hierarchical distribution. The power distribution system event comprises one of power distribution fault, power distribution abnormity and data monitoring, and the power distribution system event refers to the power distribution fault.
The power distribution system based on the hierarchy generally comprises a plurality of power distribution devices which are in communication connection in the hierarchy 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 intermediate layers which are in communication connection with the plurality of bottom layer power distribution terminals, and the intermediate layers of the embodiment are concentrators which have certain operation capacity and can store a certain amount of data.
As shown in fig. 1, a method for synchronizing events of a power distribution system based on hierarchical distribution according to an embodiment of the present invention includes the following steps:
s101, resetting a middle layer which is in communication connection with a plurality of bottom layer power distribution terminals and has faults in a plurality of power distribution devices which are in communication connection in the power distribution system hierarchical distribution;
s102, acquiring the number N0 of middle layer events and the number N1 of the plurality of bottom layer distribution terminal events after resetting;
s103, synchronizing the number of middle layer events N0 with the number of bottom layer distribution terminal events N1, such that N0 is N1;
s104, acquiring a plurality of subsequent bottom layer distribution terminal event numbers N1 ', and calculating a difference value M between the plurality of subsequent bottom layer distribution terminal event numbers N1' and the synchronized middle layer event number N0;
s105, when the difference value M is larger than 0, calling the M events.
Specifically, when a failure of a collector in the power distribution system is detected, the collector needs to be reset to ensure the normal operation of the whole power distribution system. Resetting generally refers to replacing the concentrator or formatting the concentrator. And after resetting the middle collector, acquiring the event number N0 of the middle collector after resetting and the event number N1 of the bottom-layer power distribution cabinet. The event number N0 of the intermediate collector is forced to be synchronous with the event number N1 of the bottom-layer power distribution cabinet, namely N0 is equal to N1, and the event number of the intermediate collector after reset is the same as the event number of the bottom-layer power distribution cabinet before reset. The event number of the bottom-layer power distribution cabinet is collected in real time when the concentrator runs and stored in the concentrator, and after the concentrator is reset, the event number of the concentrator is returned to zero, so that the aim of synchronization is to recover the event number stored before the concentrator fails. In the synchronization method, the concentrator can send out commands to collect the number of events of the bottom-layer power distribution cabinet, so that the number of events of the concentrator is consistent with the number of events of the bottom-layer power distribution cabinet. And after the synchronization is finished, the concentrator sends an instruction to the bottom-layer power distribution cabinet to obtain the event number N1 'of the subsequent bottom-layer power distribution cabinet, the difference value M between the N1' and the synchronized N0 is calculated, and when M is greater than 0, the obtained event number of the subsequent bottom-layer power distribution cabinet is more than that of the concentrator after the synchronization, and M event numbers need to be summoned. The summoning refers to that the 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.
By the distribution system event synchronization method based on hierarchical distribution, the number of the recorded events of the distribution cabinet or the distribution box and the concentrator at the bottom layer can be resynchronized when the concentrator fails for various reasons or needs formatting reset in a two-hierarchical distribution system, the number of the events larger than the concentrator after reset in the distribution cabinet or the distribution box at the bottom layer can be conveniently counted without repetition, the concentrator is ensured not to collect the distribution system events repeatedly, the concentrator resources are saved, and the power operation safety is guaranteed.

As shown in fig. 2, the method for synchronizing events of a power distribution system based on hierarchical distribution according to an embodiment of the present invention includes the following steps:
s201, resetting a middle layer which is in communication connection with a plurality of bottom layer power distribution terminals and has faults in a plurality of power distribution devices which are in communication connection in the power distribution system hierarchical distribution;
s202, obtaining the reset middle layer event number N0 and the event number N2 reported by the middle layer to the top layer server;
s203, synchronizing the middle-layer event number N0 with the event number N2 reported by the top-layer server, so that N0 is equal to N2;
s204, acquiring a plurality of subsequent bottom layer distribution terminal event numbers N1 ', and calculating a difference value M between the plurality of subsequent bottom layer distribution terminal event numbers N1' and the synchronized middle layer event number N0;
s205, when the difference value M is larger than 0, calling the M events.
Specifically, S201 in the second embodiment is the same as S101 in the first embodiment, and is not described herein again. After the concentrator is reset, acquiring the reset middle layer event number N0 and the reset event number N2 reported to the top layer server by the middle layer. And forcibly synchronizing the number of the middle layer events N0 with the number of the events N2 reported by the middle layer to the top server, namely N0 is equal to N2, so that the number of the events of the concentrator after the reset is the same as the number of the events reported by the middle layer to the top server before the reset. After resetting the concentrator in a three tier power distribution system, the concentrator event number is returned to zero, so the purpose of synchronization is to restore the stored event number before the concentrator failure. And after synchronization is finished, the concentrator sends an instruction to the bottom-layer power distribution cabinet to obtain the event number N1 'of the subsequent bottom-layer power distribution cabinet, the difference value M between the N1' and the synchronized N0 is calculated, and when M is greater than 0, the obtained event number of the subsequent bottom-layer power distribution cabinet is more than that of the concentrator after synchronization, and M event numbers need to be summoned.
