According to the embodiment of the invention, the information in each system is integrated, and then the power failure reason is deeply researched through whether the distribution transformer has power failure or not, so that the reason of the power failure event can be quickly determined.
In an embodiment, not only information of a fault power failure event needs to be acquired from a power distribution management system and an energy management system, but also a first power failure distribution and transformation list of the fault power failure event needs to be acquired. Therefore, the power failure distribution transformer of the distribution transformer power failure event is matched in the first power failure distribution transformer list, and the matching result of the distribution transformer power failure event and the fault power failure event is obtained.
Further, if the power outage distribution transformer matched with a power outage event in the first power outage distribution transformer list is consistent with the power outage distribution transformer of the power outage event of the power distribution transformer, the power outage event of the power distribution transformer can be determined to be the power outage event, and details of the power outage reason of the power outage event of the power distribution transformer can be obtained through the power outage event.
In an embodiment, as shown in fig. 3, a schematic flowchart of the step of matching the distribution transformer blackout event with the failure blackout event in an embodiment is provided, and the specific steps are as follows:

In this embodiment, the fault power failure event may include: at least one of a main network fault power failure event, a distribution network line trip event, a distribution network breaker trip event, and a distribution network load switch trip event. According to the power grid topology model, fault reasons can be sequentially analyzed according to feeder inlets, and therefore the reason of the fault time of the distribution transformer is obtained.
In another embodiment, in the distribution management system and the energy management system, the processing may be performed in a manner as shown in fig. 4 to obtain the first outage distribution list, and the specific steps are as follows:
In addition, when a power restoration signal is received, the power distribution management system and the energy management system can update the first power failure distribution list, but still can query the historical information of the first power failure distribution list so as to analyze historical data, for example, query the power restoration progress and the like.
Specifically, in an embodiment, the processing logic of the power distribution management system and the energy management system after analyzing the fault power failure event is as follows:
1. the main network trips to cause 10kV bus voltage loss, topology tracking power failure distribution transformation is carried out, and a corresponding distribution transformation list is generated;
2. tripping a distribution network 10kV feeder line, topologically tracking power failure distribution and transformation, and generating a corresponding distribution and transformation list;
3. tripping a distribution network 10kV intermediate circuit breaker/load switch, topologically tracking power failure distribution transformation, and generating a corresponding distribution transformation list;
4. the topology of the emergency shutdown equipment (10kV feeder line, intermediate open circuit, load switch and distribution transformer) tracks the power failure distribution transformer and generates a corresponding distribution transformer list.
Through the logic, the distribution transformation list of the fault power failure event can be accurately researched and judged.
In one embodiment, not only the planned blackout events need to be acquired from the distribution network production system, but also a second blackout distribution list corresponding to the blackout distribution and transformation corresponding to each planned blackout time needs to be acquired. Therefore, when matching is carried out, the power failure distribution change in the distribution change power failure event can be matched in the second power failure distribution change list, and the matching result of the power failure event can be obtained.
Optionally, the planned blackout event may be acquired from the distribution network production system through the OSB bus, and when the planned blackout information in the planned blackout event is updated, the planned blackout information may be updated to the terminal of this embodiment at the minute level.
In one embodiment, as shown in fig. 5, an exemplary flowchart of the step of matching a distribution outage event with a planned outage event is provided, which includes the following specific steps:
And step 506, matching the power failure distribution transformer in a second power failure distribution transformer list of the planned power failure non-transferable event, if so, skipping to the step 510, and if not, skipping to the step 506.
And step 508, stopping matching and obtaining no matching result.
And step 510, stopping matching, and obtaining a matching result of the distribution transformer power failure event and the matched power failure event.
In this embodiment, the second blackout distribution transformation list is generated by the distribution network production system, in the distribution network production system, each time the planned blackout event is issued includes the influence distribution transformation list, the distribution transformation lists may generate the second distribution transformation list, and the planned blackout event may include at least one of a planned blackout non-allowable event, a planned blackout allowable event, and a mode recovery blackout event. And setting corresponding judgment logics according to the influence degree of each planned power failure event, so that the accurate power failure reason of the distribution transformer power failure event can be obtained.
In an embodiment, in the distribution network production system, the processing may be performed in the manner shown in fig. 6 to obtain the second outage distribution list, which includes the following specific steps:
In step 604, whether the power failure distribution transformation information includes a power failure distribution transformation list or not is determined, if yes, the process goes to step 608, and if not, the process goes to step 606.
And step 608, correspondingly storing the power failure distribution list into a second power failure distribution list.
In this embodiment, the power failure distribution and transformation list may be obtained from the power failure distribution and transformation information, or the power failure distribution and transformation list may be obtained through analysis, and then stored as the second power failure distribution and transformation list, where the second power failure distribution and transformation list includes one or more power failure distribution and transformation lists of planned power failure time.
In another embodiment, the processing logic after the distribution network production system analysis plan blackout event is as follows:
1. planned blackout is not transferable and is supplied the blackout scope: the execution power failure distribution transformer is stored in a second power failure distribution transformer list, and the power failure starting time, the power failure finishing time, the actual power failure time, the actual power restoration time and the delayed power restoration time are planned;
2. planned blackout power-transferable range: the transferable power distribution transformer is stored in a second power failure distribution transformer list, and the planned power conversion starting time, the planned power conversion finishing time, the actual power failure time and the actual power restoration time are executed;
3. mode recovery impact range: and storing the mode recovery power conversion distribution transformer into a second power failure distribution transformer list, and executing planned mode power conversion starting time, planned mode power conversion finishing time, actual power failure time and actual power restoration time.
In this embodiment, through the above manner, an accurate second blackout distribution list can be obtained.
In one embodiment, if a distribution blackout event does not match a fault blackout event or a planned blackout event, the cause of the blackout may be determined by topology tracing via a grid topology model.
Specifically, the undetected power outage event is not necessarily an independent power outage event, and therefore, the distribution transformer power outage event may be determined as a suspected power outage event, and in general, the two development situations may be classified:
1. other distribution transformer voltage loss reporting signals are sequentially arranged under the same feeder line, the most possible fault position of the on-line medium-voltage line is analyzed according to the connection path of the distribution transformer and the outlet switch, and the on-line medium-voltage line can be classified as the power failure of a superior power supply.
By way of example, fig. 7 is a schematic diagram of a typical distribution network, in which a large rectangle is an outlet switch of a feeder. Gray solid represents the state is closed, and open is divided; the rectangle with small body type is a feeder line section switch, the red solid represents that the state is closed, and the hollow represents the part. Circles represent the match changes. The marked boxes indicate that power failure of a distribution transformer is determined, and if power failure events of the distribution transformer occur according to the sequence of the marked boxes, the suspected fault position studying and judging process is as shown in the following table 1:
TABLE 1
Through the judgment logic in table 1, the suspected power outage event can be converted into a determined power outage event, and thus the determined power outage event is stored as a fault power outage event.
2. The feeder line has no voltage loss caused by other distribution transformers, waits for 1 distribution transformer section measuring period, and conducts research and judgment on the distribution transformer in the next period: if the current is less than 2A, the distribution transformation state is determined as 'power failure'; if the current is larger than 2A, setting the distribution state as 'normal distribution measurement'; if the distribution current value is not available, the distribution state is set as 'distribution without measurement'. If the power failure is determined to be the single distribution transformer power failure after manual investigation. Then the operation is carried out through the interface, and the suspected power failure event is converted into the determined power failure event.
In addition, in an embodiment, the power restoration progress of the distribution and transformation power failure event can be queried according to known information, whether a power restoration signal of the distribution and transformation power failure event is received can be judged according to a preset first form, the first form includes power restoration information of the power distribution management system and the energy management system receiving the information of the fault power failure event, and the distribution network production system receives power restoration information of the planned power failure event.
Optionally, the first form may be a preset form, and the corresponding position of the form fills in the corresponding information of the distribution transformer power failure event, including a power failure start event, a planned power restoration event, and the like, and modifies the position corresponding to the first form by acquiring a power restoration signal of the power failure distribution transformer, and calculates a power restoration progress of the power failure distribution transformer.
Optionally, a second form may be further established, the metering system automatically acquires a distribution transformer power restoration signal, and when all distribution transformers associated with the power failure event receive the power restoration signal, power failure recovery is determined, and the state of the corresponding power failure distribution transformer event in the second form may be modified correspondingly. The metering system automatically collects and measures the cross section, and when the power failure distribution transformer collection distribution transformer measurement is recovered to be normal, the state of the corresponding power failure distribution transformer event in the second form can be modified by judging the power distribution transformer power restoration correspondence. The automatic switch receives switch closing remote signaling, faults of a main network line switch, a main network transformer switch and a 10kV feeder line switch are judged to be recovered, and the state of a corresponding power failure distribution transformer event in the second form can be modified by judging power distribution transformer recovery correspondence. Through the three modes, the state of the second form is modified, and meanwhile, the power restoration progress of each distribution transformer power failure event can be calculated as same as that of the first form.
