Doubly Fed Induction Generation Trainer (Model: XPO-PET/DFIG)

Rated 0 out of 5

Introducing the Doubly Fed Induction Generation Trainer (Model: XPO-PET/DFIG), this advanced educational tool is designed for in-depth studies in variable speed wind power generation. Available in two power ratings, 0.5HP and 3HP, offering versatility for different educational requirements. Features a 3-phase slip ring alternator acting as a Doubly Fed Induction Generator (DFIG) coupled to a trunnion-mounted DC shunt motor. This simulates variable speed wind power (F1) with electronic torque and speed sensors for accurate wind power input determination. Provides manual synchronization with the grid using the 3-lamp method and a synchroscope, offering hands-on experience in grid connection procedures. Equipped with a Variable Frequency Drive (VFD) using FPGA controller to supply rotor winding of DFIG (F2), allowing experimentation with variable frequency and amplitude. A 16X2 LCD is provided to observe VFD frequency.
