Abstract：Results of experiment and simulation show that low-frequency oscillation will come forth in a standalone generator-rectifier system with capacitor-resistor load when its system parameters are not reasonable. This paper detailedly studies the issue by the methods of theory computation, experiment and simulation. The system state-space model must be built firstly to finish the theory computation, which includes the simplified 2-dimension model of generator, the dynamic average-value model of diode-bridge rectifier and dynamic model of load. Then the small-signal model of system will be obtained by the linearing method at a steady-state operation point. And finally the eigenvalue theory is used to estimate the system stability. On the ground of the experiments, simulations and theory computation, this paper summarizes the law of steady-state stability of such system, analyzes the physics mechanism, and presents the control methods for the issue from points of view of parameters and controller.
