A new squirrel-cage rotor structure induction motor (IM) that has a auxiliary permanent magnet (PM) rotor and improved cage-rotor structure is presented to enhance the inherent power factor of the IM, and a prototype motor is fabricated by modifying the rotor of a conventional three-phase four-pole squirrel-cage induction motor. The flux linkage, flux distribution, power factor, core loss and e...

To ensure the profitability of wind industry, one most important objectives is to minimize maintenance costs. For this reason, components turbines are continuously monitored detect any type failure by analyzing signals measured sensors included in condition monitoring system. Most proposals for detection and diagnosis faults based on signal processing artificial intelligence models use a fault-...

the doubly fed induction generator (dfig) is one of the most popular technologies used in wind power systems. with the growing use of dfigs and increasing power system dependence on them in recent years, protecting of these generators against internal faults is more considered. loss of excitation (loe) event is among the most frequent failures in electric generators. however, loe detection stud...

The design and implementation of a new control system for reactive power compensation and mechanical torque, voltage regulation and transient stability enhancement for wind turbines equipped with fixed-speed induction generators (IGs) in power systems is presented in this study. The designed optimal linear quadratic regulator (LQR) controller provides an acceptable post fault performance for bo...

In this paper, with the assistance of some tools and a machine learning model, smart wind turbine was formed that eliminates expensive sensors reduces sensor complexity. Squirrel cage induction generator (SCIG) six rotor blades make up proposed design, depending on wind's direction, itself can rotate hub to produce energy more effectively. Additionally, two stepper motors are coupled yaw mechan...

Voltage stability margin is ensured through the reactive power resources. In order to generate references and ensure low-voltage ride-through (LVRT) control of a wind farm system based on squirrel cage induction generator, this paper proposed an optimal approach fractional-order (FO) PI-fuzzy-PI (FOPI-fuzzy-FOPI) controller. The method ensures, also, demand for active predetermined by transmiss...

Wind is one of the most widely used nonconventional sources of energy. A back-to-back PWM converter is used as the excitation power supply for the doubly fed induction generator (DFIG) wind power generation of variable speed constant frequency (VSCF).The Simulink model and control strategy of converter which is connected between rotor and grid is analyzed. Stator-flux oriented vector control ap...
