Power System Studies & Modelling

JMB Engineering delivers comprehensive power system studies using SKM Power Tools for Windows (PTW), the industry standard for electrical power system analysis in the Australian mining sector.

Our modelling team builds and maintains detailed electrical network models that form the foundation for protection coordination, fault level analysis, and system design decisions. Whether you need a new model built from scratch or an existing model updated to reflect network changes, our engineers deliver accurate, auditable results.

What We Deliver

  • Power system model development and maintenance across multiple software platforms
  • Fault level studies (three-phase, single-phase, earth fault)
  • Protection coordination studies and grading
  • Arc flash hazard assessments (IEEE 1584)
  • Load flow and voltage drop analysis
  • Motor starting studies
  • Harmonic analysis
  • Short circuit capacity assessments

As a value add, all protection modelling data including relay settings, coordination reports and study outputs are stored on our Protection Database platform — providing a full compliance record with easy lookup and access for your engineering and maintenance teams.

All studies are delivered with clear technical reports, single-line diagram markups, and actionable recommendations — ready for implementation by site electrical teams.
