摘要：

The virtual synchronous machine technology is able to control the inverter to mimic the behaviors of the traditional synchronous generator. In this paper, the rotor angle stability and its mechanism were analyzed under the second-order dynamic model of the virtual synchronous machine in a single machine (inverter) infinite bus system. The global parameter space was presented. The possible situations covering the space were analyzed and verified by real-time simulations. Furthermore, the idea of bifurcation trajectory shaping control was proposed, which can eliminate the attractor that causes the rotor angle instability by adjusting the control parameters under emergency and thus guarantee the stability. © 2019 Chin.
