Doubly Fed Induction
Generator for use in Mini-
hydro power plants
By Rizwan Rafique
Supervisor: Trond Toftevaag
Background
DFIG control in mini-hydro power generation system
Doubly Fed Induction Generators (DFIG) has been very popular and widely used in conjunction
with wind power conversion systems due to their good range of speed control with reduced
converter size as Norway produces almost all its power from hydro source which includes
from large to medium and small generation systems and usually employs synchronous
generators to convert mechanical energy into electrical.
The objective of this thesis is to perform a study whether application of a doubly-fed
induction generator in Mini-hydro power plants can be a feasible technical and economical
solution or not.
This task will be carried out by first performing the theoretical studies and simulation in
Matlab/Simulink by developing DFIG control with mini-hydro turbine and subsequently
implementing that control by establishing a laboratory setup to verify/validate the
simulation results/model while economic assessment is an optional task.
