Design

CPP’s ‘in-house' design team comprises design engineers and design drafters, providing the following capabilities:

  • Detailed design of substation primary plant and equipment layouts up to EHV installations;
  • Design of civil and structural engineering works, including equipment foundations, earthworks, buildings, steelwork, busbar systems and interplant connection systems;
  • Design of substation secondary plant and systems, this includes:
    • Integrated Control and Protection Systems (ICAP) using state of the art technology and to the IEC61850 standard where required;
    • Design and manufacture of protection and control panels;
  • Design and integration of substation SCADA and communication systems;
  • Performance of power system load flow calculations, fault level calculations and determination of protection settings using the DigSilent Power Factory suit of power system analysis software;
  • Design of overhead power lines up to 500kV using PLS-CADD;
  • Design of earthing systems using CDEGS software to comply with the IEEE - 80 and local standards;
  • Design of cable systems using CYMCAP;
  • Design of substation auxiliary systems including DC and AC power supply systems, lightning protection systems, yard lighting systems and the protection and control cabling requirements;
  • Develop all design drawings and documentation including:
    • A functional design specification (FDS) if required;
    • 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.

CPP is able to work on "greenfields" and "brownfields" projects.
