ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the
causes of decreased efficiency ....etc

Doubly-Fed Induction Generator for Variable Speed Wind Energy Conversion Systems- Modeling & Simulation
Abstract The aim of this paper is to present the complete modeling and simulation of wind turbine driven doubly-fed induction generator which feeds ac power to the utility grid. For that, two pulse width modulated voltage source converters are connected back to back between the rotor terminals and utility grid via common dc link. The grid side converter controls the power flow between the DC bus and the AC side and allows the ....etc

difference between chopper fed drives and converter fed drives pdf

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed in topic 2, where it was shown that the average output voltage could be varied by periodically switching the battery voltage on and of for varying intervals. The principal difference between the thyristor-controlled rectifier and the chopper is that in the former the motor current ....etc

INTRODUCTION


Wind turbines convert the kinetic energy present in the wind into mechanical energy by means of producing torque.
Large scale wind power projects are an attractive alternative to conventional capacity expansion.
In the present scenario , most wind turbine manufacturers now equip power generating units by induction generators.
They are operated either at fixed speed or variable speed.
Generators driven by fixed speed turbines can directly be conne ....etc
