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.

“…The self-excited induction generators compare favourably with synchronous, permanent magnet or DC generators as regards simplicity, durability, and low costs of manufacturing and maintenance. Theirs main disadvantages are unpredictable residual magnetism and weak voltage self-regulation [1,2,5,7]. Field-circuit models of the induction generators can be found in recent papers [3,4,6].…”

The paper deals with single-phase induction machine operating as a self-excited induction generator which may be used to generate electrical energy from non-conventional energy sources. Performance characteristics of the self-excited generator with capacitor connected to the both stator windings under load operating conditions are computed by field-circuit method. By changing number of turns and size of wires of the auxiliary stator winding, considerable improvement of performance characteristics of the generator were obtained with respect to no-load voltage and under load condition. Furthermore, an influence of corresponding changes in the excitation stator winding on voltage magnitude induced in excitation winding, winding currents and output power of the generator for two capacitor topology in the main stator winding have been presented. The obtained simulation results may be useful in designing the self-excited induction generator on the base of single phase capacitor induction motors.Streszczenie. Artykuł przedstawia jednofazową maszynę indukcyjną pracującą jako samowzbudny generator indukcyjny, który może być wykorzystany do wytwarzania energii elektrycznej z niekonwencjonalnych źródeł energii. Charakterystyki pracy samowzbudnego generatora indukcyjnego z kondensatorem podłączonym do obu uzwojeń stojana wyznaczone zostały za pomocą modelu polowo-obwodowego przy obciążeniu rezystancyjnym. Przez zmianę liczby zwojów i rozmiaru (średnicy) drutu uzwojenia pomocniczego stojana uzyskano znaczną poprawę charakterystyk generatora ze względu na wartość napięcia i prądu w uzwojeniu wzbudzenia generatora. Prezentowane wyniki uzyskane z symulacji mogą być wykorzystane w projektowaniu samowzbudnych generatorów indukcyjnych na bazie konstrukcji jednofazowych silników indukcyjnych.

“…Excitation capacitors should have regulated capacitance to secure self-excitation and stability of output voltage of generator during load changes. Considerable interest in induction generator was observed in last two decades when renewable energy sources became alternative to conventional sources [1][2][3][4][5][6][7][8].

“…Output characteristics of the SPSEIGs may be improved with proper design of the magnetic circuit, windings and adequate choice of capacitors. The operation range of the SPSEIGs can also be expanded with use of a simple power electronics-based scheme, such as reported in [3]. A single-phase induction motor may operate as the SPSEIG if the rotor of the machine is driven with synchronous speed or higher with the main and auxiliary stator windings electrically separated and when the capacitor is connected across the auxiliary winding (excitation winding) or/and in the main stator winding (load winding).…”

Abstract:The purpose of the paper is the investigation of possibility of utilization of a single-phase induction machine, designed and normally operating as a single-phase capacitor induction motor, as a self-excited single-phase induction generator, which can be used to generate electrical energy from non-conventional energy sources. The paper presents dq model of the self-excited single-phase induction generator for dynamic characteristics simulation and steady-state model based on double revolving field theory with two phase symmetrical components -a forward and backward revolving field for performance of the generator under resistive load. Excitation and load characteristics obtained by simulation showed considerable influence of method of capacitor configuration in the load stator winding on terminal voltage, current and output power of the generator under load. An specific construction of the stator windings together with capacitor requirements to obtain nominal output power at desired self-regulating terminal voltage over the operating range will be the aim of further research.
