“…When developing the equivalent circuit for a SPIG, some simplifications are used: for example, in [7,10,24] it is assumed that the saturation phenomenon affects only the machine magnetizing reactance X m , the core losses are neglected and the stator and rotor leakage reactances are considered equal. In many cases the per-unit (pu) rotor speed is used instead of the slip in depicting the equivalent circuit [31].…”

“…At the main winding one or two capacitors are usually connected, sometimes complementary with power electronic based converters for voltage and frequency control. The available topologies can be classified based on the number and arrangement of the capacitors required to ensure both the generator self-excitation and stable operation: i) Single winding generator -the capacitor(s) being connected across the main winding: • One (shunt) capacitor [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] (Fig. 2(a)) -power electronics can be used for parameters control [18][19][20][21][22][23];…”

The use of induction generators for electricity production in small power isolated systems represents the topic for a wide research area. As in such topologies single-phase consumers are predominant, besides three-phase induction generators with adequate balancing circuits, single-phase induction generators qualify as a reliable alternative. In the last 38 years, a significant number of research papers have tackled the problems related to the autonomous operation of single-phase induction generators (SPIGs) such as determining excitation capacitors values and their optimal arrangement, ensuring stable operation in terms of voltage and frequency balancing under varying loads and finally enhancing the quality of the energy delivered to the isolated single-phase consumers. While in case of simple topologies the operation of SPIGs is mainly investigated for fundamental electric parameters dependence with loading, excitation capacitance and speed, the use of power electronics based converters ensures stable operation over a wide range of varying/non-linear loads. This paper presents a comprehensive overview of the literature dedicated to SPIGs, focusing on several significant aspects such as main topologies, modeling, steadystate analysis and performance investigations.

Summary A self‐excited induction generator (SEIG) is one of the cost‐effective ways for power generation in remote areas. Unlike common wind energy systems, SEIG needs an excitation capacitor bank to meet the reactive power demand. The terminal voltage of the SEIG depends on the reactive power delivered from excitation capacitor bank which complicates the voltage and frequency regulation. This article presents an unbalanced loaded three‐phase SEIG system controlled by fixed capacitor and thyristor controlled reactor in order to overcome poor voltage regulation problem. Moreover, the output frequency regulation is maintained thanks to the speed controller adjusting the speed of the generator. This regulation process employs a response surface model (RSM) instead of steady state equation that determines accurately the per‐phase triggering angle of TCR and speed of the generator. Therefore, there is no need to utilize the per‐phase equivalent circuit parameters which is the major advantage of the proposed method. The feasibility and reliability of the RSM have been proven by carrying out test experiments. Experimental results of three‐phase SEIG (5.5 kW) feeding unbalanced loads have been performed to confirm the effectiveness of proposed method. According to experimental results, voltage and frequency regulations of SEIG have been well performed by using RSM within the maximum 3% regulation error.
