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;
- Management of the design of overhead power lines up to 275kV using a suitably qualified consulting engineers;
- Design of earthing systems using CDEGS software to comply with the IEEE - 80 and local standards;
- 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.
