Digital Twin Technology<\/h1>\n

Understand and Predict Power Equipment Behavior with Virtual Models<\/h2>\n

Digital twins connect measurements from physical equipment with virtual models to analyze and predict equipment condition and behavior.<\/strong><\/p>\n

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.<\/p>\n

By studying conditions that are difficult to test in the field, we support safe operation and informed maintenance decisions.<\/p>\n

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.<\/small><\/p>\n

Connecting Physical Testing with Model Validation<\/h2>\n
    \n
  1. Review Field and Test Data:<\/strong> Review the data required for the equipment, including voltage, current, frequency, loading, and temperature.<\/li>\n
  2. Model the Equipment:<\/strong> Build an analytical model reflecting equipment design, ratings, connections, and operating conditions.<\/li>\n
  3. Compare Measurements and Simulation Results:<\/strong> Compare results under equivalent conditions, investigate differences, and assess the model\u2019s range of applicability.<\/li>\n
  4. Analyze Operating Scenarios:<\/strong> Analyze equipment responses to changing conditions and fault scenarios to identify potential improvements.<\/li>\n<\/ol>\n

    Key Engineering Services<\/h2>\n

    Equipment Response to Voltage and Frequency Changes<\/h3>\n

    We study changes in supply conditions, core saturation, losses, and operating characteristics. The scope is agreed according to the equipment and available data.<\/p>\n

    Dynamic Rating, Condition Assessment, and Life Assessment<\/h3>\n

    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.<\/p>\n

    Root-Cause Analysis and Maintenance Support<\/h3>\n

    We reconstruct incident conditions in models, compare responses, and help prioritize equipment inspections and maintenance.<\/p>\n

    Developing an Integrated Engineering Support Platform<\/h2>\n

    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\u2019s operating environment and requirements.<\/p>\n

    Information for Your Consultation<\/h2>\n

    Tell us about the equipment, the problem to be addressed, ratings and connection details, available test and operating data, and your preferred schedule. After reviewing the information, we will propose a modeling scope and approach.<\/p>\n
