Low speed, high torque machines are used in wind turbines where the turbine rotor is directly connected to generator. A permanent magnet synchronous generator using high-energy rare-earth magnets (PMs) one common choice for this application, but PMs have supply insecurities and cost risks. free 32-pole PM generator, ferrite a spoke-type rotor, use 12 kW experimental built tested. Voltages curre...

This paper presents automatic reactive power control of the isolated wind-diesel hybrid power systems. The synchronous generator (SG) is used for power generation from diesel and the induction generator (IG) is used for electric power generation from wind turbine. To minimize the gap between reactive power generation and demand, the variable sources of reactive power is used such as static sync...

Local renewable resources such as wind and solar are often available in remote locations. Wind farms consist of many individual wind turbines which are connected to the electric power transm­iss­i­o­n ne­tw­o­r­k­. A wind farm can use the wind resources from a certain area efficiently. Double-fed induction generator (DFIG) is a gene­rating principle widely used in wind turbine (WT). DFIG are ab...

In this project a modular simulink Implementation of an Induction generator is described in step-step approach.with the modular system each block solves one of the model equations.This particularly for highly wind generated areas and Induction generator with inverter system creates a hybrid system.This hybrid system inherently adapts to the changes in rotor speed or load on the generator while ...

Wind energy development is consumer and environment friendly, it requires shorter construction time compared to thermal, nuclear generation and is cost competitive. It becomes one of the most competitive sources of renewable energy. However, wind power has some disadvantages. For example, wind power is considered an intermittent power supply because wind does not blow 100% of the time. Besides,...

In the history of civil aircraft transportation, ice formation has been identified as a key factor in safety flight. Anti-icing and deicing systems have emerged through years with aim to prevent or eliminate on wing airfoils, control surfaces probes. Modern flying machines demand more efficiency order reduce carbon footprint increase sustainability flight transport. achieve this goal, need an e...

in this paper an adaptive pid controller for wind energy conversion systems (wecs) has been developed. theadaptation technique applied to this controller is based on reinforcement learning (rl) theory. nonlinearcharacteristics of wind variations as plant input, wind turbine structure and generator operational behaviordemand for high quality adaptive controller to ensure both robust stability an...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

Helicopters are well-known by their hovering capabilities. However, the performance of this valuable feature can be seriously affected by external disturbances such as wind effects. The latter could be even more significant when dealing with small-size helicopters, which are commonly adopted as base platforms for developing unmanned aerial vehicles. Motivated by this context, this work proposes...

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...
