Progressive power grid multi-professional data association fusion method and device

Abstract

The invention discloses a progressive power grid multi-professional data association and fusion method and device. The method comprises the steps of subjecting the full-service data center data to thedata access according to structured data, unstructured data and mixed data; carrying out data unification on the accessed data according to a pre-established unified power grid equipment model, wherein the unified power grid equipment model comprises a common model and a characteristic model; carrying out progressive association fusion on the unified data step by step according to a voltage level, a connection relationship between devices and a device inclusion relationship; and verifying the correlation fusion condition, screening out unmatched data, and performing re-matching to obtain allcorrelation fusion data of the power grid multi-specialty data, and storing the data in a power grid equipment comprehensive database.

Description

technical field [0001] The disclosure belongs to the technical field of smart grids, and relates to a progressive grid multi-specialty data correlation fusion method and device. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In recent years, centering on the construction requirements of the State Grid Corporation's "three sets and five majors" system, the company's headquarters and provincial companies have gradually strengthened the construction of information systems, and established a comprehensive information platform that runs through all levels, integrates various businesses, and highly shares information. Digital assisted decision-making has improved the intelligence and informatization level of power grid production, operation, marketing and other majors; formed an intensive, unified, efficient and collaborative work mode, and bu...

Problems solved by technology

[0007] However, during the research and development process, the inventor found that because the data of each major now has different emphases, there is a lack of effective correlation and fusion among the data, forming data islands, such as production management system (PMS), energy management system (EMS), power grid GIS platform There is the same substation or a transmission line in each system, but the data codes in each system are different, and no effective correlation can be made. When performing professional diagnosis and analysis of power grid planning, there is a lack of effective calculation factors and cannot provide reliable support.

However, the manual method of data association and fusion has a large workload, low efficiency, and the quality of association cannot be guaranteed. At the same time, the incremental data association cannot be carried out normally. Therefore, it is necessary to design a multi-disciplinary data association and fusion method for power grids with the help of information technology. Realize the connection of various professional data, and provide data support for power grid diagnosis analysis and load forecasting calculation
