Abstract
Although power quality (PQ) disturbances events such as rms variations and transients occur in transmission and distribution systems, these datasets are mostly managed through proprietary solutions in different data formats. This paper presents a simple, yet effective, metadata database schema to manage voluminous PQ disturbance events in power systems. A database constructed using the schema can be used to store the metadata providing descriptive and analytical analysis of the disturbance events. Proposed schema defines five classes to store the metadata associated with PQ disturbance events: event, time-series, description, software analysis, and IEEE disturbance classification. The classes that form the schema are presented, then are demonstrated using actual disturbance events captured from a distribution system.
