Wind conditions in South Africa are suitable for small-scale wind turbines, with wind speeds below 7 m.s-1. This investigation is about a methodology to optimise a full wind turbine using a surrogate model. A previously optimised turbine was further opti...

Off grid telecom base stations in developing nations are powered by diesel generators. They are typically oversized and run at a fraction of their rated load for most of their operating lifetime. Running generators at partial load is inefficient and, ove...

With appropriate vibration modeling and analysis the incipient failure of key components such as the tower, drive train and rotor of a large wind turbine can be detected. In this paper, the Nonlinear State Estimation Technique (NSET) has been applied to ...
