This paper presents the voltage build-up process and the terminal voltage control of a stand-alone self-excited induction generator (SEIG) using direct vector control (DVC) technique under variable speeds and different types of load. Here, the three-phase SEIG is excited by a pulse-width modulated voltage source inverter (PWM-VSI) connected to a single-capacitor on the DC side with a start-up battery...
A robust adaptive nonlinear controller is designed for a Doubly-Fed Induction Generator (DFIG) wind turbine connected to a power grid. The controller main objective is to regulate the generator terminal voltage and rotor speed. A model based control design strategy is adopted. The controller structure and equations are obtained following a backstepping control design method using the DFIG reduced...
According to the mathematical model of the doubly-fed induction generator (DFIG) and the field-oriented vector-transformation control technique, the control strategy of the variable-speed constant-frequency wind power generator is analyzed which can realize the decoupling control of active power and reactive power of DFIG. On the experimental platform of the DFIG system which is based on TMS320LF2812,...
This paper presents analysis, design, and simulation for vector oriented control of three-phase voltage source pulse-width modulation (PWM) inverter which aims to optimize the utilization of wind power injected into the grid. To realize this goal, a digitally controlled converter-inverter system is proposed which provides economic utilization of the wind generator by insuring unity power factor operation...
This paper presents a performance analysis of wind-powered self-excited induction generator (SEIG) and a vector-controlled pulse-width modulation (PWM) converter. Three-phase voltage-source converters are the building blocks of a great number of power electronic systems. The origin of difficulties in the control of the above converters is in their nonlinear nature. The PWM current control technique...
Induction generators operating in a stand-alone mode are increasingly being used in isolated areas. Such a generator has very poor voltage regulation. This paper proposes a simple thyristor-switched capacitor (TSC) type voltage regulator for a stand-alone induction generator to maintain voltage within the upper and lower acceptable limits. The capacitor size in each TSC branch is selected very carefully...
