Due to the advantages of a self-excited induction generator (SEIG), it plays a main role in sources of renewable energy, such as wind turbines (WT). The regulation of terminal voltage and frequency is poor under variable rotor speed and load conditions at stand-alone operation mode. The generator terminal voltage depends on the excitation capacitance which can be controlled by a capacitor bank and static voltage compensator. The dynamical model of the machine is described by differential equations in D-Q axes transformations of the synchronously rotating frame. Many models of analysis are proposed in the literature. In those models, several approximations are used to simplify the process of calculations, such as neglecting the iron core resistance, stray load resistance, stator and rotor leakage reactance, and magnetic saturation. In this work, a comprehensive dynamic model of the SEIG-WT is performed to analyze the system performance under transient and steady-state conditions. This dynamic model considers the effect of all machine parameters variation. New analytical formulas are used for to accurate calculation of minimum and maximum values of excitation capacitance and generator rotor cut-off and maximum speed. The dynamic model results are partially compared with experimental results, and accurate agreement is shown.

This paper describes the development of a three-phase induction motor (TIM) drive speed controller. A rule-based fuzzy logic controller (FLC) is developed for TIM speed control in non-linear systems. Speed control applications are tested by conducting simulations under different operating conditions. To achieve reliable TIM operation, the space vector pulse width modulation (SVPWM) scheme is used to generate gate signals for the three-phase, two-level inverter. The SVPWM technique demonstrates excellent performance in TIM speed control. The scalar control (V/f control), which is inexpensive, simple to implement in hardware, and applicable to medium-and high-speed rated TIM applications, is used to control the developed TIM. Results show that the implementation of rule-based fuzzy with V/f control and the SVPWM technique for TIM speed control provides superior performance, which is sufficiently robust and intelligent for real-time applications.

“…The non-conventional energy sources are going to be depleted increasingly day by day, based on a survey the oil will be reach low level in about 40 years and the coal reserves will be depleted in about 120 years. Therefore, the new millennium belongs to renewable energy sources [1][2][3][4][5][6]. Sometimes in rural and remote areas, where it is difficult to install the transmission and distribution line, for such an areas SEIG is found to be suitable for power generation from such renewable energy sources due to its inherent advantages [7] such as low cost, simple construction, little maintenance, absence of dc source, brushless etc compared to conventional generator.…”

This paper illustrates the newly developed specially designed single phase self excited induction generator. All possible configurations for winding arrangement have been attempted to obtain the best output from the model. The earlier configurations were found incomplete to obtain the optimum output from the single phase induction machine as an induction generator. The proposed model is unified, optimum and accurate for inculcating the performance of single phase induction generator. The model design as well as its development of 3.7 kW, 50 Hz and 4-pole single phase SEIG is presented using simulink in MATLAB. The 4 possible configurations are designed for single phase SEIG, the objective function is to reduce total harmonic distortion (THD) and optimize the model parameter. The results were demonstrated experimentally validated using SPEED software. A standard available IEC 132 frame size is used for development of proposed model and the results found are prominent. HIGHLIGHTS It is found that there is heavy demand for small capacity power generation in single phase rating as almost electrical appliances are operated on single phase supply. The main objective of this research is to develop a novel and a specially designed SEIG and to analyze its performance analysis The 1-phase SEIG is proposed with rating 3 - 5 kW. The input parameter for single phase SEIG such as power, voltage, impedance, frequency, pole pair the stator/rotor resistance etc are theoretically analyzed Afterwards the parameters are act as input for SPEED software the results are obtained and found to be impressive one with practical applications Four possible configurations for a single phase SEIG are proposed. The four possible configurations have been attempted to achieve the objective of research. On comparing the performance of these models, it has been observed that the model - “Short pitch (1-8) Double layer distributed winding” gives good performance in terms of reduced THD, sinusoidal m.m.f. waveforms GRAPHICAL ABSTRACT
