摘　　要：根据由李亚普诺夫定理导出的综合阻尼系数的原理，统一定义了同步发电机的动态阻尼力矩系数和动态同步力矩系数。对同步发电机的阻尼力矩产生的机理进行了分析，并指出了使电力系统稳定装置产生阻尼力矩的同时，不致减少动态同步力矩的理论方向。A unified definition for damping torque coefficient of synchronous machines is proposed in this paper according to the principle of synthetic damping coefficients deduced from the Lyapunov Theorem. The damping characteristics of synchronous machines with and without automatic voltage regulator are analyzed using this method. In addition, a theoretic direction of how to make PSS add its damping torque without sacrificing the synchronous torque of the machine is promoted.
