The 3 phase slip ring alternator acts as DFIG coupled to trunnion mounted DC shunt motor simulating variable speed wind power (F1) with electronic torque & speed sensors mounted to determine wind power input accurately.
Manual synchronization with grid provided using 3 lamp method & synchroscope.
Variable frequency & variable amplitude VFD provided using FPGA controller to supply rotor winding of DFIG (F2).
16X2 LCD is provided to observe VFD frequency
Multifunction Measurement AC analysers (MMM) read the rotor input voltage /power and stator voltage /power & frequency.
Experiments with ON grid & OFF grid measurements to verify F1± F2 algebraic addition of shaft frequency & VFD frequency to match supply grid frequency.
Facilitates easy and safe wiring by students due to use of 4mm sturdy Shrouded banana patch cords and shrouded socket arrangements for high voltage circuits
Each panel has ABS molded plastic sturdy enclosure, and colorful screw less overlays showing circuits diagrams & its connection tag numbers for easy understanding and connection
