Background
The power outage causes are complex, the outage signals are not associated, a plurality of devices report the outage signals within the same period of time, the accuracy is unreliable, the outage signals received by the lower-level devices are possibly due to the fact that the nodes at the upper level are faulty, and the accuracy of the outage signals at the current position cannot be perceived. In the prior art, china patent with application number 202310283398.3 discloses a layering study and judgment method and system for power failure faults of 10kV lines and below, wherein the method comprises the following steps: obtaining lines, distribution transformers and user tables from a database, and carrying out association to obtain a wide table of the unit-line-area-user relationship; acquiring line power failure events, distribution transformer power failure events and user power failure events from a database, and removing false alarm data; generating a power failure event of a box by a user power failure event, and supplementing and generating a distribution transformer power failure missing report event; generating a branch power failure event by the distribution transformer power failure event, and supplementing a main power failure missing report event; and (3) carrying out layered research and judgment on the power failure event, eliminating repeated messages, and generating accurate research and judgment messages. Under the existing conditions, huge investment is not additionally increased, the power failure event data of each level is utilized to comprehensively judge the power failure, the fault part is defined, and finally the fault is positioned to a main line, a branch line, a distribution transformer, a meter box and a user, so that accurate rush repair is realized, and the operation and maintenance quality effect is improved. In the prior art, the power grid topology is realized by taking equipment as a node, in the power grid topology, information is transmitted to a main node layer by layer in a hierarchical mode, and the equipment or the system related to the main node is used for analyzing to obtain the accurate fault position; however, when a power failure occurs, the equipment involved in the power failure needs to report power failure information in the existing power grid topology, so that information congestion occurs in upper nodes very easily, a large amount of power failure information can be abandoned in the congestion, and information loss is caused; meanwhile, the power failure information reported to the related equipment or system of the main node also needs to be processed and analyzed uniformly, and under the condition of information deficiency, the information is difficult to distinguish which information is accurate information, and which information is false-report information, so that the accurate positioning of specific power failure faults is not facilitated.
Disclosure of Invention
In order to at least overcome the defects in the prior art, the purpose of the application is to provide a power outage research and judgment data analysis method and system based on a power grid model.
In a first aspect, the present application provides a power outage research and judgment data analysis method based on a power grid model, including:
constructing information nodes for key parts of a target power grid, and hanging equipment of the key parts on the information nodes constructed on the key parts;

when the number of first outage signals received by the outage nodes in the power grid topology from the child nodes is larger than a first preset proportion of the number of the child nodes of the outage nodes, or the outage nodes are leaf nodes in the power grid topology, the outage nodes send first outage signals to father nodes of the outage nodes; the power failure node is an information node which receives a first power failure signal sent by the child node or a first power failure signal sent by the hung equipment;
the power outage node requests a power outage signal from a brother node of the same father node as the power outage node in the information node, and receives a second power outage signal fed back by the brother node; the brother nodes are child nodes corresponding to the same father node;
and the power failure node judges whether the power failure node is a fault node with power failure fault according to the first power failure signal and the second power failure signal received by the power failure node, and reports the fault signal when the power failure node is the fault node.
When the method and the device are implemented, the topological network is not built by taking the power grid equipment as a node, but information nodes are built at key positions, and equipment corresponding to the key positions is hung through the information nodes, so that the power failure information of the equipment at the key positions is summarized, and meanwhile, the rapid networking during the increase, the decrease and the replacement of the equipment at the key positions is facilitated. The power grid topology is constructed according to the hierarchical relations of different key parts, the nodes are information nodes, and the topological hierarchy and the connection relation are consistent with the power grid hierarchical relation between the key parts.

In the embodiment of the application, in order to reduce congestion caused by power failure information reporting, a mode of judging the state of the information node is adopted. The power failure node is an information node which receives a first power failure signal sent by the child node or a first power failure signal sent by the hung device, namely the information node defines itself as the power failure node when receiving the first power failure signal sent by the child node or the first power failure signal sent by the hung device, and starts a judging algorithm corresponding to the power failure node to judge whether the information node is in a power failure state or a power failure fault.
