New harmonized data models

Harmonization repository is dedicated to those data models that are mostly accepted and only requirements of consistency, complete documentation and examples availability.

Here there is a list of coming data models in different domains:

New data models on Energy

New data models on Energy

There are two data models coming for the Energy domain (ACMeasurement and InverterDevice). You can submit an issue on it if interested.

Once harmonized with the contributors and checking the interaction with other data models they will be incorporated into the Energy repository inside the domain of Smart Energy.

ACMeasurement

The Data Model intended to measure the electrical energies consumed by an electrical system which uses an Alternating Current (AC) for a three-phase (L1, L2, L3) or single-phase (L) and neutral (N). It integrates the initial version of the data Modem [THREEPHASEMEASUREMENT], extended to also perform single-phase measurements. it includes attributes for various electrical measurements such as power, frequency, current and voltage.

Additional Information about Attributes : For some attributes such as current and voltage the value is a structured value with properties for the Single-Phase (L) or three different phases (L1, L2 and L3). For some measurements such as the different power types (active, reactive and apparent power) there is an attribute for the total from all phases. The rules are defined as below : – Three Phase – Total = L1 + L2 + L3 – Single Phase – Total = L.

For most of the attributes, there are various ways they can be actually measured. For this purpose the measurementType Meta Data Attribute can be used. It can have the following values:

When using the values [average, rms, minimum, maximum], another metadata attribute called measurementInterval should be used to give the length of the measurement period in seconds. Also the Meta Data timestamp attribute should be the end time of the measurement period.

InverterDevice

The Data Model is intended to describe the mechanical, electrical characteristics of an Inverter according to DC – Direct Current Information supplied as input and AC – Alternating Current Information returned as output.

Additional Information about Data Model: This Data Model can be used directly as the main entity to describe the device [INVERTER] or as a sub-entity of the Data Model [DEVICE] using a reference by the refDevice attribute.
