PSCAD consultancy & EMT studies

PSCAD consultancy and electromagnetic transient (EMT) studies for grid connections where fast converter controls, protection, BESS, HVDC, IBR and weak-grid behaviour decide the result. We build, validate and run PSCAD/EMTDC studies using detailed, vendor-specific equipment models and defensible TSO submission evidence.

When it's needed

When this study is needed.

  • The connection involves inverter-based resources (IBR), HVDC or other fast power-electronic controls whose dynamics RMS models approximate.
  • The point of connection is electrically weak (low short-circuit ratio) or close to other converters.
  • A network operator requires EMT evidence for fault ride-through, fast fault-current injection or control stability.
  • Phenomena of interest sit below or around the fundamental frequency, or involve harmonics and waveform detail.
Method

How we approach it.

  1. Agree the study question, the point of connection and the grid code or specification that applies.
  2. Assemble the EMT model: network equivalent, plant, and vendor black-box or detailed control models.
  3. Validate the model against expected steady-state and known benchmark responses before drawing conclusions.
  4. Define the scenarios and operating points that could govern the result, then run the time-domain cases.
  5. Interpret waveforms against the acceptance criteria and document assumptions, limitations and findings.
Software

Tools we use.

  • PSCAD / EMTDC (primary EMT environment)
  • PowerFactory and PSS®E for RMS context and model exchange
  • Scripted automation for batch scenario runs and post-processing
Scenarios

Scenarios & operating points.

  • Balanced and unbalanced faults at and near the connection point
  • Range of grid strengths / short-circuit levels and X/R ratios
  • Credible dispatch and outage combinations
  • Voltage and frequency disturbances across the required envelope
Deliverables

What you receive.

  • Validated PSCAD model files and a model-quality statement
  • Documented methodology, assumptions and scenario list
  • Result waveforms with interpretation against the criteria
  • A written report suitable for independent review by the operator
Quality & validation

Evidence that stands up to review.

Every conclusion is traceable to a validated model and a documented scenario. We record tool versions, model sources and assumptions so the work can be reproduced and challenged — the standard a network operator's review expects.

Selected work

Comparable experience.

Case-study write-ups for this service are in preparation. To discuss directly relevant project experience, brief us — we can talk it through, under NDA where appropriate.

FAQ

Questions engineers ask.

When do I actually need EMT rather than RMS?
When the question depends on fast converter controls, fault ride-through, fast fault-current injection, harmonics, or sub-/super-synchronous interactions. RMS remains fine for steady-state, load-flow and slower dynamics; many projects use RMS for breadth and EMT for the cases that govern the result.
Can you work from a vendor's black-box model?
Yes. Most IBR and HVDC studies use the manufacturer's encrypted control model in PSCAD. We integrate and validate it within the network model; where a detailed model is available, we can use that instead.
What makes an EMT model “credible” to an operator?
A documented validation against expected behaviour, clearly stated assumptions, the right scenarios, and an evidence trail (model sources, tool versions, settings) that a reviewer can reproduce.
