What We Do

Design

We have specialist capability in:

Design

  • civil and structural engineering works, including equipment foundations, earthworks, buildings, steelwork, busbar systems and interplant connection systems
  • substation primary plant and equipment layouts up to EHV installations
  • substation secondary plant and systems, including, integrated Control and Protection Systems (ICAP) using state of the art technology which meets the IEC61850
  • the design and integration of substation SCADA and communication systems
  • overhead power lines up to 500kV using PLS-CADD
  • earthing systems using CDEGS software to comply with the IEEE - 80 and local standards
  • cable systems using CYMCAP
  • substation auxiliary systems including DC and AC power supply systems, lightning protection systems, yard lighting systems and the protection and control cabling requirements
  • power system load flow calculations, fault level calculations and determination of protection settings using the DigSilent Power Factory suit of power system analysis software


Drawings and Documentation

  • all detailed design drawings covering the disciplines of protection and control, electrical, civil and structural engineering and earthing installations
  • building layouts and functional requirements
  • calculation of protection settings
  • preparation of substation I/O lists and the configuration of substation RTU's
  • determination and configuration of protection relay logics
  • preparation of commissioning plans (where required)
  • preparation of Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) documentation
