Wind Turbine

Wind Turbine (WTG)

The Wind Turbine is a core asset type in the Bazefield platform representing a single utility-scale wind turbine in a power plant. It serves as the foundational asset for collecting, organizing, analyzing, and visualizing operational and performance data. Each turbine asset is uniquely identified and associated with a parent site (e.g a “wind farm”), a collection feeder, and optional substation, forming part of the broader asset hierarchy of a wind farm.

Functional Description

A Wind Turbine converts kinetic energy from wind into electrical power using aerodynamic blades connected to a rotor and generator system. The wind turbine is the primary AC Power Conversion asset in a wind power plant (see Domain Categories for a broader description of other AC Power Conversion assets across different power plants).

Core Data Model

While the data model of individual turbines may vary by vendor, Bazefield offers a pre-installed CORE data model to account for the most common points, events, and attributes relevant to all makes and models of wind turbines. Model by model variations are then handled typically through smart Model Inheritance. All vendor specific points, calculation, and events are packaged in separate asset model templates, and are not described here.

Example of a common Modelling Strategy to encompass variations of data between turbine manufacturers and site specific SCADA configurations.

Core Attributes

Attributes are fixed key, value pairs used to represent non-time series data associated with each asset (read more about Attributes). While attribute values can differ from asset to asset, critical shared (e.g. CORE) attributes defining a wind turbine asset type, pre-installed in Bazefield are described below. These are often pre-requisite data required for the Bazefield applications to function fully.

Required for basic Bazefield Core functionality

Optional attributes for common additional modelling

Attributes marked with “** “ are only applicable to North American clients with wind farms requiring to submit GADS Performance and event reporting.

Depending on your version of Bazefield, there may be additional advanced attributes not listed here to support data integrations or migrations with other systems.
