Engineering design
The electrical and civil aspects of wind farm construction are critically important and must therefore be designed carefully to provide optimum 'performance per cost' for your wind project.
The wind farm's internal electrical network is connected to all individual wind turbines and the power is collected and transmitted to a central point which is then delivered to the power grid through a centralised substation. The design of the internal network and substation is important to reduce power losses and therefore maximise efficiency.
The wind turbine foundations, internal access roads and drainage, and control and monitoring buildings must be designed and specified prior to the construction phase. A well-engineered civil design, especially for the foundations, leads to significant reductions in construction costs.
Our world-class engineering team carry out the electrical and civil designs related to wind power projects by utilising state-of-the-art design tools combined with our extensive experience in wind power engineering projects. Our services include:
Design of electrical infrastructure, including:
1- Central substation at the point of connection (POC), whether owned by the wind farm or by the electricity network operator;
2- Underground cable networks and/or overhead lines, forming radial ‘feeder’ circuits to strings of wind turbines;
3- Electrical switchgear for protection and disconnection of the feeder circuits;
4- Transformers and switchgear associated with individual turbines;
5- Reactive compensation equipment, if necessary; and
6- Earth (grounding) electrodes and systems.
Design of civil infrastructure, including:
1- Roads and drainage;
2- Wind turbine foundations;
3- Central substation foundation;
4- Met mast foundations; and
5- Buildings housing electrical switchgear, SCADA central equipment, and spares and maintenance facilities.
Design of Supervisory Control and Data Acquisition (SCADA) system, including:
1- Central computer;
2- Fibre optics cables to each turbine and met mast;
3- Wind speed and other meteorological transducers on met masts; and
4- Electrical transducers at or close to the POC.
