Description
Technical field
The present invention relates to intelligent substation technical field, and in particular to a kind of intelligent substation big data excavates application side
Method.
Background technology
At present, domestic each grid company has all carried out intelligent substation pilot, future, in the overall background that intelligent grid is built
Under, the fast development of intelligent substation also becomes inexorable trend, how more efficiently using intelligent substation bring it is big
Data message is the intelligent substation technology further development and application problem to be solved.
With intelligent substation popularization, develop rapidly and apply, advantage of the intelligent substation relative to traditional transformer station
Gradually manifest, intelligent substation can provide more abundant data message and be applied for analysis, rely on intelligent substation data network
The extensive construction of network, intelligent substation big data has good application value.But, current intelligent substation big data is not
Its is real performance, mainly there is following some problem：1st, it is current both at home and abroad in the technical research of intelligent grid big data and
The trial that engineer applied aspect is done, as a whole, still in the starting stage is explored, the research and application of intelligent grid big data are
One long-term and complex work；2nd, the Interoperability of intelligent grid Communication Information System is still present, and data model is not yet
Unified, this brings practical difficulty to the acquisition and application of data；3rd, there is data point to disperse the characteristics of intelligent substation big data,
There is strict relativity between the features such as data volume is big, and data.Intelligent substation big data is broadly divided into two classes, and a class is come
From in original sampling data, a class comes from the interoperability data between equipment in addition.This two classes data has in common that number
Relativity between, excavates the relativity that application mode considers these data, especially currently without a kind of good big data
