This article presents a mathematical model by which the dynamic behavior of a self-excited single-phase reluctance generator (SESPRG) can be successfully predicted under different operating conditions. The proposed analysis is based on the d - q axis model. Self-excitation is achieved via capacitors connected across the terminals of both the main and auxiliary windings. Dynamic stability of the proposed generator is studied using the linearized model. In order to achieve maximum damping characteristics, the machine parameters are optimized using the torque decomposition algorithm. An improved dynamic stability with well-damped hunting oscillations has been achieved using the present approach. Excellent agreement between experimental and simulated results have been observed, which supports the validity of the proposed analysis.
