The growing amount of information produced by automatic systems is often associated with the paradigm of Big Data. Next to this approach it remains the interest in integrating information of different origin within a shared framework, conceptually able to be formalized by an ontology. The IEC Common Information Model (CIM) is a natural candidate to take on the role of reference ontology in the electrical context being able to describe different types of electrical domain information (eg. topologies of electrical networks, market information, metering, etc.) in an integrated way.

The activities described here have adopted the CIM standard as a reference semantic model for the representation of information gathered from Power Quality (PQ) monitoring of medium voltage distribution networks, in order to demonstrate the possible synergies with the types of information already provided in that model, namely those associated with topological and cartographic information. The result of this integration could also be in perspective leveraged in the context of the deployment of the 2° generation of Italian meters that will include Power Quality data.
