“…Various techniques for improving voltage regulation such as a switched capacitor scheme, electronic load controllers, variable VAR controllers and other solid state controllers have been reported in the literature [28][29][30][31][32][33][34][35]. These techniques improve the performance of a SEIG significantly, but involve complex and expensive control hardware, hence militating against SEIG's features of simplicity and reliability [2].…”

“…To achieve a given voltage level in an SEIG, an external capacitor bank must be able to supply the magnetising current of that level. Necessary background literature on the steady-state performance analysis, selection of excitation capacitors and transient performance analysis of SEIG has been obtained from 13 different sources [23][24][25][26][27][28][29][30][31][32][33][34][35].…”

Self-excited induction generators (SEIGs) will play an important role in off-grid wind power generation. To advance understanding of the significance and prospects of SEIGs, this paper elucidates the significance of incorporating the proximity effect in the conventional model of self-excited induction generators. The researchers offer an analytical model to incorporate the proximity effect in the rectangular rotor bars of the SEIG. The model's accuracy relies on a computer program. The calculated results are experimentally verified in the case of two 7.5 hp aluminium-and copper-rotor SEIGs under open-circuit and static loading conditions, through an exclusive qualitative analysis of terminal voltage build-up at no-load, variation in terminal voltage and frequency, as a function of the proximity effect. The paper examines also the voltage regulation, frequency regulation and excitation capacitance requirements of both aluminium-and copper-rotor SEIGs.

Abstract:The Self Excited Induction Generator (SEIG) is an isolated power source, whose terminal voltage and frequency are controlled by the excitation of capacitance or the load impedance. A new strategy based on an active power filter (APF) for controlling the current and power quality of the self-excited induction generator (SEIG) is also presented in this paper. The proposed active filter proved to play an important role and give good dynamic response and robust behavior upon changes in load parameters. This investigation demonstrated that power average control strategy can facilitate the improvement of the power quality. This control method extracts fundamental (reference) components of the source current for the shunt active power line conditioners for nonlinear loads and unbalanced loads. The shunt APF in conjunction with the proposed controller perform perfectly under different steady state and transient conditions. The simulation results with nonlinear loads and unbalanced loads have showed the effectiveness of the proposed scheme for harmonic reduction in Wind based Power Generation.

“…In [6] is presented a classification of topologies known and applied in voltage regulation, all related to the control of reactive power balance. Among the exposed techniques, which employs a Distribution Static Compensator (DSTATCOM) connected in parallel to the AC bus can be identified as what offering better voltage regulation and freedom of control [7][8][9][10][11][12]. The DSTATCOM performs the adjustment of the bus voltage by the compensation of reactive power of the system in order to keep the unity power factor.…”

This paper deals with the development of an adaptive control system applied to voltage regulation of a standalone distributed power generation system, fed by self-excited induction generator. The generation system considers a four wire three-phase grid, composed by three phases plus neutral conductor, fed by three-phase three wires induction generator. The neutral conductor is created from the neutral point of star connection of excitation capacitors. The four-wire configuration allows the connection of three-phase loads in star or delta configuration, as well as single-phase loads. The voltage regulation is performed through a four-legs distribution static compensator (DSTATCOM) shunt connected to the AC bus. The adaptive controller proposed offers suitable voltage regulation in conditions of system's parameters variations such as, load connection and disconnection, and changes in induction generator's unmodeled parameters. The proposed generating system was simulated in MATLAB, where simulation results were obtained to show the good performance of the voltage regulation control system during the connection and disconnection of three-phase loads. Additionally, some preliminary experimental results are presented as well.
