Speed regulation of a wind turbine with current source or matrix converter: Tuning procedure

Application of matrix converter connected to wind energy system

“…Where 𝑃 𝑚 represents the generated power, 𝑣 𝑤 is the wind speed in m/s, ρ is the air density in 3 , 𝐴 𝑟 the turbine rotor area in 2 , (𝐴 𝑟 = 𝑟 2 , where 𝑟 is the rotor blade radius) and, 𝑐 𝑝 a power coefficient. The power coefficient can be calculated as a function of tip speed ratio and rotor blade pitch angle θ according to (2) [10,11].…”

“…Wind generators have been generally utilized in autonomous systems for Feeding loads which fall outside the scope of the electrical network. WT can be classified in two type first horizontal axis configuration, second vertical axis configuration [3,4]. As a result of the numerous advantages of using a self-excited induction generator in converting the captured mechanical energy from WT made it suitable for use in small and medium size WECS.…”

A Modified Open Loop Control of a Matrix Converter Connected to Wind Energy System

“…AC can be directly converted to AC with different voltage rms value and different frequency by using a MC without using any DC link [2,3]. And this is the bold feature of MC over rectifier-inverter converter, so MC can be considered an emerging alternative to the conventional rectifier-inverter converter [4][5][6][7]. Independent control on the output voltage magnitude and frequency can be provided by utilizing a MC.…”

A different model of WECS connected to smart grid through matrix converter

“…To get rid of this problem, to obtain stable and high-quality electricity, appropriate control and the right converter must be designed. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”
