Design and Comparison of Grid Connected Permanent Magnet Synchronous Generator Non-salient Pole and Salient Pole Rotor Wind Turbine

Abstract

Variable speed wind turbines are widely used wind
energy conversion system (WECS). Among them doubly fed
induction generator (DFIG) and permanent magnet synchronous
generator (PMSG) are mostly used. PMSG based wind turbines
are getting more popular in recent times because of their several
advantages over other types. Direct drive capability and low
speed operation are some of its significant advantages over other
type. In the dq0 reference frame, this analysis discusses the
implementation and simulation of a Simulink-based operated
permanent magnet synchronous generator (PMSG) wind turbine.
The current control subsystem makes use of PID controllers to
regulate the wind turbine's velocity, direct and quadrature stator
currents, and blade pitch tilt. The pitch angle controller monitors
both the generator's speed and active strength, restricting both in
the event of high-speed wind conditions. PMSGs exhibit constant
excitation that is uncontrollable. As a result, a properly designed
damper winding is needed to ensure stable operation in the
absence of a frequency controller. This article analyzes and
compares the performance of three-phase non-salient pole
permanent magnet ac machines and salient pole machine fitted
with damper windings in rigid network operation. The
recommendations for network-connected generators are
determined by evaluating the results of a circuit-based
mathematical models of the PM-machine. Variable speed wind turbines are widely used wind
