Embodiment 1
[0065] The invention provides a method for constructing a database of transformer sensing quantities supporting dynamic data repair, such as Figure 1-Figure 2 shown, including the following steps:
[0066] Step (1) Forming a real-time sensing quantity database based on the on-site sampling sensing quantity data of the power transformer;
[0067] In a specific implementation manner of an embodiment of the present invention, the method for forming the real-time perception quantity database includes:
[0068] The on-site sampling perception data of the power transformer is stored in the corresponding real-time state quantity data table; the real-time state quantity data table is queried by text or ID retrieval method, including ID number, sampling name, sampling value, sampling frequency and sampling type, etc. variables, see image 3 . The definition of the real-time state quantity data table is as follows:
[0069] Live Data Table → {"Live Data Table"}or{ID} (1)
[0070] ...
Embodiment 2
[0131] Based on the same inventive concept as that of Embodiment 1, an embodiment of the present invention provides a transformer sensory quantity database construction device that supports dynamic data repair, including:
[0132] The first forming unit is used to form a real-time perception quantity database based on the on-site sampling perception quantity data of the power transformer;
[0133] The second forming unit is used to detect abnormal perception quantity data in the real-time perception quantity database and form an abnormal data index table;
[0134] The third forming unit is used to classify the perception quantity data in the real-time perception quantity database according to the sampling frequency, and store the perception quantity data at each sampling time in the corresponding historical perception quantity data table to form a classification information index table and a historical perception quantity database ;
[0135] The first update unit is used to q...
Embodiment 3
[0140] Based on the same inventive concept as in Embodiment 1, an embodiment of the present invention provides a system for constructing a database of transformer sensing quantities that supports dynamic data repair, including a storage medium and a processor;
[0141] The storage medium is used to store instructions;
[0142] The processor is configured to operate according to the instructions to execute the method according to any one of Embodiment 1.
[0143] Those skilled in the art should understand that the embodiments of the present application may be provided as methods, systems, or computer program products. Accordingly, the present application may take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present application may take the form of a computer program product embodied on one or more computer-usable storage media (including but not limited to disk storage, ...
