“…Since most of the resistive loads fed by isolated power systems are based on a single-phase system, a single-phase generator is a better choice. Generally, three-phase generator systems are widely used due to their advantages such as less maintenance, modest protection, and lower investment cost [3,4]. However, a three-phase induction machine can be modified to generation mode to supply single-phase load [5].…”

“…However, a three-phase induction machine can be modified to generation mode to supply single-phase load [5]. A three-phase squirrel cage induction machine is cheaper, it has good efficiency, and is available at higher power ratings (more than 3 kW) as well [3,6]. Furthermore, a squirrel cage machine can operate as a self-excited induction generator (SEIG).…”

“…Wang and Lee [13] also proposed a three-capacitor circuit scheme, as well as a method to estimate the values of self-excited capacitors, which allow the SEIG to be balanced. In another study, Anagreh and Iqteit [3] proposed a scheme that provides acceptable phase balance and large output power. Bhattacharya and Woodward [14] studied SEIG excitation balancing for maximum power output.…”

In the present study, a new strategy of analysis was used to determine the optimal interval of a single-phase resistive load to operate a fixed-speed wind turbine. The essence of this optimal range is to enable the generator to have stable voltages and current balances, large power, and an acceptable frequency range, and also mitigate generator overheating. The generator windings and excitation capacitances were prepared according to the C-2C connection scheme with suitable values of excitation capacitances. The admittance matrix of the system was based on positive and negative sequence generator voltages and was calculated by symmetrical components theory. The generator performance was found through optimization of the determinant admittance matrix magnitude. Moreover, balanced position of the generator can be achieved near the maximum load power. Consequently, the best interval of resistive load of the generator (1.5 kW) was found around 2% voltage unbalance factor. The appropriate optimal load was approximately ±6% of the perfect balance resistive load value.

Purpose This paper aims to deal with a modified-based approach for the evaluation of the steady state performances of three-phase self-excited induction generator (SEIG) feeding single-phase load. Design/methodology/approach Using the symmetrical components method, the proposed approach is based on a modified model of unbalanced three-phase SEIG, which is formulated similarly to the well-known model of balanced three-phase SEIG. Owing to this modified model, the determination of the SEIG operating point amounts to the resolution of two semi-decoupled nonlinear equations for two unknowns; the magnetizing reactance and the per-unit frequency. A simple resolution method based on an iterative two-step technique is used. The results obtained by the proposed approach are compared with those given by a conventional approach and are validated experimentally. Findings The proposed approach is as accurate as the conventional approach. Further, for the same accuracy degree, the proposed approach permits to speed up the resolution when compared to the conventional approach, as only few iterations are required for the convergence. The proposed approach was also successfully used for the steady state analysis of SEIG under generalized unbalanced loading conditions. Practical implications The determination of the operating point of the generator is based on a modified model of the generator and a simple iterative resolution method. The calculation technique can be implemented on low resource controller to provide online voltage control of the SEIG. Originality/value The paper contains two main originalities. The first one consists in a modified formulation of the SEIG model under unbalanced loading conditions. The modified formulation permits the use of the well-known model of balanced three-phase SEIG. Unlike previous ones reported in the literature, the proposed model does not require tedious algebraic manipulations. The second originality is the use of two-step technique to solve the equations, which permits to avoid laborious mathematical derivations and manipulating high-order polynomials.
