The rapid depletion of conventional sources for power generation necessitates the need of renewable energy power plants. Renewable sources primarily wind and solar are available free of cost and counts for cleaner source of energy thereby reducing environmental concern. The potential of wind energy needs to be harnessed effectively for optimum power generation. Present research aims at comparis...

Squirrel-cage induction motors play an important role in the world’s industry. Hence there is a strong demand on their reliable and safe operation. Their faults and failures can lead to excessive downtimes and generate enormous costs due to reduced output, emergency maintenance and lost revenues. In this paper a FEM model of a three phase squirrel-cage induction machine is presented. It is used...

The power quality analysis is an essential issue in the integration of distributed energy resources to grid. Recent standards regulate harmonics disturbances due increasing penetration intermittent sources interconnected with grid employing converters. This paper aims analyze wind turbine system based on a Squirrel Cage Induction Generator (SCIG) driven by Electromagnetic Frequency Regulator (E...

This paper proposes a high-order sliding mode control (HO-SMC) with the super-twisting (ST) algorithm for maximum power point tracking (MPPT) and grid-connected wind energy conversion system (WECS), based on squirrel-cage induction generator (SCIG). The main features of this strategy are attenuation chattering phenomenon inherent in first-order its robustness against external internal disturban...

Condition monitoring is an important issue in the maintenance of electrical machines. In the last years several methods for fault diagnosis of the squirrel-cage induction motors were cited in the literature. Among these methods the Motor Current Signature Analysis (MCSA) is considered the most effective non-invasive fault detection method, because it can easily detect all the common electrical ...

The paper describes a variable speed wind generation system where fuzzy logic principles are used for light load efficiency improvement and optimization. A squirrel cage induction generator feeds the power to an improved topology of matrix converter which pumps power to a utility grid or can supply to an autonomous system. The power factor at the interface with the grid is controlled by the mat...

The paper discusses the different possible techniques to self excite the slip ring induction machine working as self excited induction generator. The generated voltage due to self excitation is initiated and sustained with constant value of power capacitors connected across the stator windings. Attention is focused on the influence of different techniques on generator voltage and output power c...

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,...
