This article proposes a cascade proportional-integral second-order sliding mode control (PI-SMC) method for matrix converter-fed brushless doubly fed induction machine (BDFIM). The PI-SMC consists of PI speed controller with an inner-loop (SMC). provides reference to the SMC constraints according system requirements in terms maximum current and speed. As discontinuous sign function traditional ...
This paper presents a control strategy for a grid connected doubly fed induction generator (DFIG)-based wind energy conversion system (WECS).Control strategies for the grid side and rotor side placed in the rotor circuit of the Doubly Fed Induction Generator (DFIG) are presented along with the mathematical modeling of the Wind Energy Conversion System. In this control approach, wind generators ...
The Brushless Doubly-Fed Reluctance Machine (BDFRM) has been widely investigated in numerous research studies since it is brushless and cageless there no winding on the rotor of this emerging machine. This feature leads to several advantages for machine comparison with its induction counterpart, i.e., Induction (BDFIM). Less maintenance, less power losses, also more reliability are major BDFRM ...
Abstract— The doubly-fed induction machine used as a wind turbine generator has recently received a great attention from the industrial and scientific communities. The reason is twofold: first, this machine easily produces a fixed frequency voltage from the stator windings when the rotor is driven at variable speed; second, the excitation power electronics converter feeding the rotor windings n...
In a wind power generator using doubly fed induction generator (DFIG), the three-phase pulse width modulation (PWM) voltage source converter (VSC) is used as grid side converter (GSC) and rotor side converter (RSC). The standard linear control laws proposed for GSC provides not only instablity against comparatively large-signal disturbances, but also the problem of stability due to uncertainty ...
The use of doubly fed induction generator in wind power plants has result in new necessities to maintain a reliable operation of the network. The tendency of the grid codes is to require the ability from the wind power plant to keep connected during and after grid disturbance, similarly to the synchronous generators requirements. This paper analyse the behaviour of a wind power plant equipped w...
A novel model reference adaptive system for the rotor position/speed estimation and sensorless operation of a brushless doubly fed reluctance generator with maximum power point tracking is presented. Its main advantage over existing designs are inherent robustness stability afforded by complete parameter independence using only measured currents converter-fed (secondary) winding. In addition, r...
Received Sep 19, 2017 Revised Oct 27, 2017 Accepted Nov 11, 2017 This paper present steady state and dynamic (Transient) models of the doubly fed induction generator connected to grid. The steady state model of the DFIAG (Doubly Fed Asynchronous induction Generator) has been constructed by referring all the rotor quantities to stator side. With the help of MATLAB programming simulation results ...
