Comparison of Dynamic Performance of Two Generators of Permanent Magnetics and Induced Magnets Sync Using Two-way Nutrition in Wind Turbines and Improving Their Performance by Considering MPPT

Wind energy is one of the most important renewable energies ,and its capacity for installation in distribution networks increases every day. It is said that over the past 10 years, wind power installation capacity has doubled on average every three years. These generators have variable speed performance as wind speed changes. In this paper, the performance of these two generators has been investigated at various wind speeds and it can be seen that these two generators have a good response to wind speed variations, and by using MMPT (Maximum power point tracking), Maximum power is obtained from the wind. These generators are connected to a three-phase network through a power electronics converter with back IGBT / DIODE switches. For the network side and the generator side, there is a single-channel converter, which acts as a circuit-breaker on the side of the network as a reed switch and converter on the side of the generator as an inverter, and the switching of these converters operates through bandwidth modulation PWM (Pulse width modulation). Between these two converters, the interface capacitor is used that this operates as source of voltage DC. Controllers have been used to control each of these converters, which can be used to maximize power from the wind.
