The Savonius wind turbine is a type of vertical axis wind turbine (VAWTs) that is simply composed of two or three arc-type blades which can generate power even under poor wind conditions. A modified Savonius wind turbine with novel blade shapes is introduced with the aim of increasing the power coefficient of the turbine. The effect of blade fullness, which is a main shape parameter of the blad...

In this work, a second-order sliding mode control algorithm is proposed for variable speed laboratory size DC generator wind turbine experiment system in order to track a speed profile and operate the wind turbine at maximum power extraction. The turbine torque, which varies with the wind speed, is considered as an unknown disturbance and rejected by the sliding mode strategy. The sliding mode ...

The constant expansion of wind power plants and ever increasing energy needs result in a need for wind turbine installation in areas with complex terrain and highly turbulent winds. Wind turbine control during such winds is very difficult task that often cannot be efficiently accomplished by classic wind turbine control system. This paper presents a novel approach to the wind turbine control in...

Variable-speed, fixed-pitch wind turbines are required to optimize power output performance without the aerodynamic controls. A wind turbine generator system is operated such that the optimum points of wind rotor curve and electrical generator curve coincide. In order to obtain maximum power output of a wind turbine generator system, it is necessary to drive the wind turbine at an optimal rotor...

due to increasing expansion of energy consumption and also the decrease and tendency towardsending fossil energy reserves, the current energy cycle needs to use alternative energy speciallywind energy, because it’s considerably cheaper than other recycling sources. the presentresearch investigates suitable possibility of exploiting wind energy to create wind power stationin soltanieh zone of za...

A wind farm’s overall power production is significantly less than its nominal power, defined as the sum of turbines’ rated outputs. The primary cause for this significant loss exposure downstream turbines to aerodynamic wake their upstream counterparts. Wind farm layout optimization aims at minimizing such adverse effects by finding optimal turbine positions that are exposed wake. Over past few...
