You can manage large-scale wind farms where hundreds or thousands of wind turbines stream real-time data on performance metrics, operational state, and environmental conditions. The architecture integrates weather monitoring data through MQTT streaming and maintains comprehensive metadata and asset information on various types of turbine equipment to create a unified wind farm platform.

Architecture overview

The wind farm maintenance reference architecture uses Microsoft Fabric Real-Time Intelligence to create a unified platform that processes real-time data from wind turbines and integrates weather monitoring data for intelligent maintenance management. You can implement the architecture with four main operational phases: Ingest and process, Analyze, transform and enrich, Train, and Visualize and activate.

IoT events from wind turbines are transmitted with sub-second latency through Azure Event Hubs to Eventstreams.
Regional weather monitoring devices provide real-time data on wind speed, direction, temperature, and humidity. These devices send data to an MQTT broker, and Eventstream subsequently gathers the data.
Data Factory synchronizes asset metadata, including rotor blade generators, from the ERP system to OneLake.
Incoming telemetry is directed to Eventhouse, where the system processes vast amounts of data in sub-latency seconds. This processing aids in uncovering turbine related insights.
The system enhances and contextualizes turbine data by using asset metadata. This process results in organized tables that are ready for straightforward access.
The system establishes shortcuts in OneLake for maintaining long-term aggregated logs.
The system trains and evaluates advanced machine learning models in real time, facilitating the detection and prediction of maintenance issues.
Our ontology is defined by entities and semantic relationships that utilize aggregated data from OneLake to create a unified and digital representation of physical assets.
Real-Time Dashboard provides a high granularity view of all incoming telemetry with easy correlation to the asset trends.
Power BI generates high level reports providing yearly and monthly view on power generation and other business insights.
Activator is triggered to generate real time notifications on anomalies.

The following sections explain each operational phase in detail.
