Nonlinear Mppt Control of Squirrel Cage Induction Generator-wind Turbine
This paper presents a nonlinear control method to track the maximum power point of wind turbine equipped with Squirrel Cage Induction Generator (SCIG). Since the mechanical power of wind turbine is function of its shaft speed at a given wind velocity, the proposed controller provides the desired voltage at the output of Voltage Source Converter (VSC) so as to control the generator speed and the...
متن کاملRotor Fault Detection of wind turbine Squirrel cage Induction Generator using Teager-Kaiser Energy operator
This paper proposes the use of the Teager–Kaiser energy operator (TKEO) for the detection of a broken rotor bar (BRB) in a squirrel cage induction generator, which is used usually in wind energy systems. The TKEO is investigated using the non-stationary signals representation in the time/frequency domain by sensing the estimation of the instantaneous amplitudes and frequencies present on the st...
متن کاملFault-tolerant Control of a Wind Turbine with a Squirrel-cage Induction Generator and Rotor Bar Defects
Wind turbines are usually installed on remote locations and in order to increase their economic competence malfunctions should be reduced and prevented. Faults of wind turbine generator electromechanical parts are common and very expensive. This paper proposes a fault-tolerant control strategy for variable-speed variable-pitch wind turbines in case of identified and characterised squirrel-cage ...
متن کاملImproving Transient Stability in a Grid-Connected Squirrel-Cage Induction Generator Wind Turbine System Using a Fuzzy Logic Controller
A common problem in wind power plants involves fixed-speed wind turbines. In fact, being equipped with a squirrel-cage induction generator (SCIG), they tend to drain a relevant amount of reactive power from the grid, potentially causing voltage drops and possible voltage instability. To improve SCIG power quality and transient stability, this paper investigates a new control strategy for pitch ...
متن کاملActive Power Control in Wind Driven Variable Speed Squirrel-Cage Induction Generator
ISSN 2250 – 1088 | © 2011 Bonfring Abstract--This paper describes active power control in a grid connected variable speed wind electric generation system (WEG) using squirrel cage induction machine. The chosen variable speed WEG system consists of a wind turbine, squirrel-cage induction generator, an AC-DC-AC interface and the power grid. In this work the generator side converter is controlled ...
