Abstract

The construction of wind turbine generator set depends on the sufficient measurement of wind resources, and reasonable layout and management. Flat open terrain is the ideal condition for the operation of the wind turbine, but the actual terrain fluctuation is changeable. Because these terrains are close to the areas where the electricity is demanded, the wind farm construction and development have more urgent and practical needs. In this paper, a typical mountainous terrain wind shear is studied by numerical simulation. ERS-100 wind turbine is chosen to analyze the performance in the typical mountainous terrain from four respects of wind profile, turbulence intensity, yaw and terrain blockage. The results showed that: turbulence intensity is the important factor affecting the aerodynamic performance, which leads to the large performance loss in nearly 50% at leeward slope; wind profile near the top of the hill is close to the ideal uniform flow and loss was low, but the performance loss is nearly 30% at the foot; the installation yaw angle is small, which has a minor effect on performance; terrain blockage only impact on windward slope.
