AN ARTIFICIAL LOGIC CONTROLLER IMPLEMENTATION OF HIGH PERFORMANCE VARIABLE FREQUENCY DRIVER WITH INTERLEAVED CONVERTER

Variable frequency drive uses power electronics vary the frequency of input power to motor, thereby controlling motor speed. AC motor drives are widely used to control the speed of ACs,pumps, blower speeds, machine tool speeds, conveyor systems speeds and others applications that require variable speed with variable torque. This paper proposes ...

ACTIVE VOLTAGE CONTROL FOR DFIG-BASED WIND FARM INTEGRATED POWER SYSTEM BY COORDINATING ACTIVE AND REACTIVE POWERS

Large-scale wind farms are generally integrated by long-distance transmissions, but power grids cannot sufficiently support the access point voltage of these wind farms. The access point voltage undergoes a stability problem under wind speed variations. However, the reactive power compensation device cannot reconcile the requirements of response sp...

Power Quality Improvement Using Dynamic Voltage Restorer

Power system consist of large number of nonlinear load which causes power quality issues. Sensitive components like electronic devices, medical equipment working on power supply are vulnerable to power quality problems. Voltage sag ,Swell ,harmonics ,noise are considered to be some important power quality issues .Voltage dips are the major disturb...
