| Component | Purpose | Technology used | Impact |
|---|---|---|---|
| Edge Data Connector | To fix the compatibility gap, our team implemented an edge-based data connector that could pull real-time data from the SCADA system and standardize it for cloud compatibility. | MQTT (Message Queuing Telemetry Transport) and OPC UA (Open Platform Communications Unified Architecture) protocols, for a seamless data translation from SCADA’s proprietary format to a cloud-compatible format. | This connector bridged the SCADA and cloud environments, enabling the continuous flow of data without impacting the SCADA system’s core functionality |
| Cloud Data Lake Integration | The team set up a cloud data lake to store the standardized SCADA data in a scalable format, enabling high-performance processing and storage for historical and real-time data. | AWS S3 for storage, and AWS Glue for ETL (Extract, Transform, Load) processes, which allowed for on-demand data transformation and ensured easy scalability for future data expansions | Data lake acted as a central repository, enabling data analysts and maintenance teams to access both real-time and historical performance data, driving predictive insights and facilitating ML applications. |
| Predictive Analytics Dashboard with ML Integration | To turn data into actionable insights, the team created a predictive analytics dashboard that used machine learning models to detect anomalies and forecast potential equipment failures. | Amazon SageMaker for building and training ML models on SCADA data, while Tableau was used for the visualization of real-time predictive maintenance alerts and asset health status. | With this dashboard, maintenance teams received early warnings on potential issues, allowing them to schedule preventive measures, which minimized unplanned downtime by over 40%. |
- Reduced Downtime: Predictive maintenance led to a 40% decrease in unplanned downtime, saving substantial operational costs and improving grid reliability.
- Increased Data Accessibility: SCADA data was now available to cross-functional teams, enhancing collaboration and insight generation.
- Scalability: With data housed in the cloud, the company could scale its analytics and connect additional assets without further infrastructure changes.
