Embodiment
[0063] Such as figure 1 As shown, in this embodiment, the public or private transformers are equipped with a gateway meter, which conforms to the national grid standard, and the communication protocol adopts the DL / T645-2007 or DL / T645-1997 standard protocol. Through this protocol, the gateway meter collects and records many parameters of the transformer.
[0064] In this embodiment, the transformer parameters collected in real time by the gateway table are analyzed through the big data algorithm, the transformer can be monitored and warned, and the corresponding relationship between the distribution line and the public transformer and the dedicated transformer can be detected to find the wrong line topology.

The invention discloses a line topology checking method and system based on power failure information big data analysis. The line topology checking method comprises the steps: S1, acquiring power failure information of a gateway meter installed on a transformer; S2, performing logic analysis on the power failure information, and filtering redundant data information and interference data; and S3, analyzing, processing and mining the filtered power failure information by adopting a big data mining method, finding out an abnormal line change relationship, and rectifying the line change relationship. The line topology checking system comprises a gateway meter, data processing equipment and a server, wherein the gateway meter collects and records various parameters of the transformer; the dataprocessing equipment comprehensively collects data in the gateway meter in a power failure time period and transmits the data to the server; and the server analyzes the data and stores the data into adatabase. Technical guidance is provided for carrying out line change relationship field investigation, and technical support is provided for lean marketing management.
Description
technical field [0001] The invention relates to a power distribution system, in particular to a line topology checking method and system based on big data analysis of power outage information. Background technique [0002] The power distribution system is a key link to ensure the quality of power supply, provide high-quality services, and improve the operating efficiency of the power system and the ability to accept renewable energy. In recent years, in the process of building a smart distribution network, due to the large number of distribution network components, heavy expansion tasks, and frequent equipment changes, the workload of topology data management and maintenance is heavy, and data entry and update are not timely. Or the line-to-line change relationship is inconsistent with the actual power grid operation, which brings great troubles to the dispatching, operation, and management of the distribution network, and the verification of the distribution network topolog...
