Digital Twin Technology
Understand and Predict Power Equipment Behavior with Virtual Models
Digital twins connect measurements from physical equipment with virtual models to analyze and predict equipment condition and behavior.
Powerlink uses PSCAD to model transformers, conductors, circuit breakers, protective relays, and other equipment, comparing simulation results with field data for validation. These models support root-cause analysis, operating condition studies, and equipment condition and life assessments.
By studying conditions that are difficult to test in the field, we support safe operation and informed maintenance decisions.
The time and cost savings shown in the diagram describe the intended benefits. Actual analysis time and results depend on model size, computing conditions, and the scope of validation.
Connecting Physical Testing with Model Validation
- Review Field and Test Data: Review the data required for the equipment, including voltage, current, frequency, loading, and temperature.
- Model the Equipment: Build an analytical model reflecting equipment design, ratings, connections, and operating conditions.
- Compare Measurements and Simulation Results: Compare results under equivalent conditions, investigate differences, and assess the model’s range of applicability.
- Analyze Operating Scenarios: Analyze equipment responses to changing conditions and fault scenarios to identify potential improvements.
Key Engineering Services
Equipment Response to Voltage and Frequency Changes
We study changes in supply conditions, core saturation, losses, and operating characteristics. The scope is agreed according to the equipment and available data.
Dynamic Rating, Condition Assessment, and Life Assessment
We assess operating capacity and aging using loading, ambient temperature, and equipment condition data. Life prediction requires operating history and modeling assumptions; we explain the applicable conditions and uncertainties alongside the results.
Root-Cause Analysis and Maintenance Support
We reconstruct incident conditions in models, compare responses, and help prioritize equipment inspections and maintenance.
Developing an Integrated Engineering Support Platform
Powerlink aims to develop a platform connecting modeling, testing, and diagnostic results. Integration with asset management systems and cloud services is scoped according to each client’s operating environment and requirements.
