摘要：
The basic principle of subsynchronous resonance (SSR) and self-excitation is presented. Utilizing the formula of linear network theory, a network state equation suitable for the analysis of SSR and self-excitation is built. Combining with state equation of synchronous generator, a method to interface the state variables of generators with those of network is deduced, and the state equations of power system are built. Whether SSR or self-excitation occurs or not can be judged by eigenroots and the impacting factors on SSR or self-excitation can be judged by correlation factors. Case calculation results show that the proposed method is feasible.
