Wind Farm

Wind Farm (WF)

A Wind Farm in Bazefield represents a collection of wind turbines and supporting balance of plant equipment grouped geographically or operationally under a single entity, with a single tie-in to the external grid. It acts as a parent-level object that aggregates operational, financial, and availability data from all associated turbines. Wind Farms are commonly used to model ownership structure, grid-level reporting, and SCADA-level oversight across a fleet.

Functional Description

A Wind Farm (also known as a Wind Power Plant) is a utility-scale facility designed to convert the kinetic energy in the wind into alternating current (AC) electrical power. This is achieved through a coordinated array of wind turbines, each equipped with a generator and control system. The combined electrical output of these turbines is typically collected at an on-site substation, where it's transformed and fed into the electrical transmission grid via a single point of interconnection (POI).

In Bazefield, the Wind Farm object type represents this entire power-producing entity — enabling monitoring, control, and reporting at the plant level. It serves as the top-level structure for aggregating turbine-level data, managing grid-level compliance, and analyzing overall site performance.

Logical Site

A wind farm asset type is specifically a Logical Site.

In Bazefield, the concept of a site is split into two layers — Physical Site and Logical Site — to provide accurate modeling of complex facilities that host multiple grid-connected systems. A Logical Site represents a distinct operational unit within a physical facility, usually aligned with a single point of interconnection (POI) to the electrical grid. It includes the set of assets (e.g., turbines, inverters, batteries) and control boundaries responsible for generating or storing power under a specific market registration, utility agreement, or revenue stream.

A Physical Site represents the shared physical facility or location where power-generating assets are installed. This includes common infrastructure such as access roads, fencing, communications equipment, and substations. A physical site typically maps to a real-world geographic footprint and can encompass multiple independent or dependent logical sites.

An example of how to use physical site asset types and logical site asset types together in modelling is shown below. Here a large, 4-phase wind powerplant is modelled as a Physical Site Wind Facility 1, with logical sites Wind Plants 1-4 as children.

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 a wind farm. Model by model variations of wind farms of different underlying vendors are then handled typically through smart Model Inheritance. The image below shows an example model hierarchy of how inheritance can help organize the data for a large group of wind farms in a fleet.

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

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.

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.
