A Novel Voltage and Frequency Control Scheme for a Wind Turbine Driven Isolated Asynchronous Generator
نویسندگان
چکیده
This paper deals with the control of voltage and frequency of a wind turbine driven isolated asynchronous generator. The controller consists of an IGBT (Insulated Gate Bipolar Junction Transistor) based 3-leg voltage source converter and a battery at its DC link. The controller is having bidirectional flow capability of active and reactive powers by which it controls the system voltage and frequency with varying wind speed and load conditions. Inverted sine carrier pulse width modulation switching strategy is used in VSC to enhance the fundamental output voltage and to minimize the switching losses. The proposed system is simulated in MATLAB using Simulink and PSB (Power System Block-set) toolboxes.
