Technical Field

[0001] The present invention relates to the technical field of data management, and in particular to a data management method and system based on electric power business. Background Art

[0002] The main business of the power business is power supply and cable maintenance. Some companies are two different companies that also provide power generation and power generation equipment manufacturers. The power business is an important basic service to maintain the operation of modern society. It is not only related to economic development, but also directly affects people's daily life. With technological progress and policy adjustments, the power industry is also constantly developing and changing. With the rapid development of science and technology, the development of power business is becoming more and more intelligent. In particular, when conducting data management of power business, a data management system for power business is needed.

[0003] At present, due to the large amount of complex data in the power business and the huge scale of data faced by power grid companies, the power business may have inaccurate, repeated or inconsistent data, and it is impossible to detect whether the power business data is abnormal in time. At the same time, after discovering the data abnormality, how to process and analyze it in real time and how to ensure its timeliness and accuracy, it is impossible to coordinate plans for the power business system, which affects the timeliness of power business data management. In addition, the power grid status of the power business cannot guarantee unified and standardized management, resulting in a cumbersome data management process and the inability to guarantee the power grid operation efficiency during the power business operation.

The system according to claim 1, characterized in that: The multimodal management terminal includes a data detection module, a data detection module, a data management module and a management tracking module; The data detection module includes a data detection unit and a data analysis unit; The data detection unit is used to detect the power grid data at the corresponding time in real time through the power grid data detector, and the power grid data includes data of power generation, transmission, transformation, distribution, power consumption and dispatch in the power business; The data analysis unit is used to calculate the difference between the data of each link of power generation, transmission, transformation, distribution, power consumption and scheduling detected at the corresponding time and the standard power generation, transmission, transformation, distribution, power consumption and scheduling data. If the corresponding difference = 0, the data is judged to be normal; if the corresponding difference ≠ 0, the data is judged to be abnormal.

8. The system according to claim 7, characterized in that: The data positioning module includes a positioning compensation unit, which is used to perform real-time compensation based on the calculated data difference. The compensation method is: if the difference is a positive number, the corresponding data difference is reduced; if the difference is a negative number, the corresponding data difference is increased; The data management module includes a multimodal adjustment unit, which is used to adjust the multimodal fusion solution of power grid data by data integration.

9. The system according to claim 8, characterized in that: The management and tracking module includes a line loss analysis unit and an analysis and tracking unit; The line loss analysis unit is used to monitor the equipment in the power grid in real time through data monitors and sensors, including real-time monitoring of the status of transformers, lines and switchgear; The analysis and tracking unit is used to track the equipment and line loss in the power grid in real time through a data tracker and a timer.

10. A data management method based on electric power business, referring to the data management system based on electric power business according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Establish a power grid data transmission connection channel for the power business, enter the data identification terminal, collect power grid data in real time, track the power grid data in real time, monitor the quality of power grid data in the power business in real time, and judge whether the power grid data is abnormal in real time; Step 2: Enter the data coordination terminal, judge the quality of power grid data in the power business, coordinate the system and operate the plan. According to the judgment result of power grid data quality, select the best data coordination plan and track the plan. During the plan tracking process, compare the quality of power grid data in real time. Step 3: Enter the multimodal management terminal, through real-time detection of the power grid status in the power business and real-time data analysis of the power grid status, determine whether the power grid status at the corresponding moment of the power business is abnormal, and monitor the power grid operation results in real time through line loss analysis.
