Fault-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 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 کاملNonlinear 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 کاملOff-the-grid compressive sensing for broken-rotor-bar fault detection in squirrel-cage induction motors
In this paper, we propose an off-the-grid compressive sensing based method to detect brokenbar fault in squirrel-cage induction motors. To validate our method, we first build a dynamic model of squirrel-cage induction motor using multi-loop equivalent circuit to simulate motor current under fault conditions. We then develop an off-the-grid compressive sensing algorithm to extract the fault char...
متن کاملFault-tolerant Control of a Wind Turbine with Generator Stator Inter-turn Faults
Faults of wind turbine generator electromechanical parts are common and very expensive. This paper introduces a generator fault-tolerant control scheme for variable-speed variable-pitch wind turbines that can be applied regardless to the AC generator used. The focus is on generator stator isolation inter-turn fault that can be diagnosed and characterised before triggering the safety device. An ...
