The use of wind turbines is increasing at very high rates in many countries around the world. Studies to evaluate the impact of connecting these new generation units to the existing power systems must be done. This paper proposes a wind energy conversion system for a grid connected permanent magnet synchronous generator (PMSG) and power electronic converter system. The model includes a PMSG mod...

Direct drive wind turbine generators are gaining importance for light weight, compact design in wind power generation. A new design approach of superconducting wind generator having both axial and radial air gaps between stator and superconducting rotor winding is selected for this simulation work. This paper deals with the simulation of magnetic flux distribution in stator and rotor coil of th...

The development of renewable energy brought new complex combinatorial optimization problems as the one studied here: the conception of an autonomous hybrid energy system. Such systems involve several sources of energy, see for instance [1], [2] and [3]. In this paper we study the optimization of the design of a hybrid system including photovoltaic arrays, wind turbines, batteries storage and an...

Planetary gearboxes are widely used in the drivetrain of helicopters and wind turbines. Any planetary gearbox failure could lead to breakdown of the whole drivetrain and major loss of helicopters and wind turbines. Therefore, planetary gearbox fault diagnosis is an important topic in prognostics and health management (PHM). Planetary gearbox fault diagnosis has been done mostly through vibratio...

Future missions to Saturn's giant atmosphere-shrouded moon Titan may involve aerial platforms such as airships or helicopters. A significant challenge is the navigation of such vehicles, both in terms of global position determination and path planning in the zonal wind field, and for local stationkeeping to acquire organic surface samples of astrobiological interest. This paper overviews the Ti...

This paper describes the modeling and simulation of a wind energy conversion system in Matlab/Simulink environment. The wind energy conversion system consists of a wind turbine, gear box, and induction generator. The dynamic model of a 30 kW induction generator is used for performance testing of the proposed system. Simulink models of the individual components of wind energy conversion are form...

With rapid development of wind power technologies and significant growth of worldwide installed capacity of wind power, wind energy conversion system has become a focal point in the research of renewable energy sources. This paper provides comprehensive reviews of past and present power electronics converter topologies applicable to various wind turbine systems with different generators. An ove...

This paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. The methodology is based on a modified sliding mode observer (SMO) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. The faults are reconstructed using the equivalent output err...
