Single-Phase Self-Excited Reluctance Generator, Part I: Steady-State Analysis

A method of steady-state analysis of a single-phase, self-excited reluctance generator based on a qd model and harmonic balance technique is proposed. A necessary constraint function is derived to reveal the parametric dependency of the system which has a combination of self-excitation and nonlinear characteristics. Moreover, the proposed method can be used to reconstruct the machine waveforms, which can provide a better understanding of the system. The comparison between experiment and simulation shows a good agreement. This method not only offers guidance for the design of a single-phase, self-excited reluctance generator, but also provides a general methodology for other self-excited generator steady-state analysis under unbalanced terminal conditions.
