The performance of three-phase Self-Excited Induction Generator (SEIG) with Static Synchronous Series Compensator (SSSC) is investigated to feed various static loads. The employed SSSC is a three-phase, Insulated Gate Bipolar Transistor (IGBT) based, PWM operated, Current-Control Voltage source converter (CC-VSC). The reference current to generate the gating signals is obtained by employing only one...
This paper presents a performance analysis of wind-powered self-excited induction generator (SEIG) and a vector-controlled PWM converter. Three-phase voltage-source converters are the building blocks of a large 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 is used to derive the switching...
In this paper, according to the characteristic of AC-excited variable speed constant frequency wind turbine generation, stator voltage orientation vector control strategy is adopted in double-fed induction generator (DFIG). Firstly, the paper studies the running characters of DFIG, and the principle of DFIG under no-load cutting-in condition. Then according to the mathematical model of DFIG under...
For doubly fed induction machines operating as wind generators (DFIG), the terminal voltage and the active power delivered to the grid are controlled by a PWM converter linked to the machine rotor. The monitoring of the direct and quadrature axis components of the rotor voltage makes possible the control of the terminal voltage and active power, respectively. Currently, this control is performed by...
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...
