摘　　要：参数匹配不当的 3/3 相双绕组发电机系统并联运行时会发生低频振荡而不能正常工作。为了对系统稳定运行的条件进行研究,该文建立了系统的等效电路模型、线性化数学模型及相应的状态空间方程。在此基础上,证明了该类系统并联运行时存在交互振荡和负载振荡两种振荡模式,并从运行稳定性的机理出发,得出了相应的的运行稳定性判据。揭示了该类系统并联运行稳定性和单机运行稳定性之间的关系。实验与理论分析结果的对比说明了所建模型和分析方法的正确性。If the parameters of the paralleled 3/3-phase double winding generators and its load do not match, low-frequency oscillation will occur in the system and result in its breakdown. In order to study the conditions for the stable operation of the system, the equivalent circuit model, linearized mathematical model and corresponding state space model are developed for the system. It is verified that two types of oscillations exist within the multiple paralleled double winding generators: oscillation between any two double winding generators, oscillation between all of the double winding generators and its load. Corresponding criterions of operational stability for both types of oscillations are obtained according to physical interpretations of operational stability. The relationships of operational stability between multiple paralleled double winding generators and single double winding generator are illustrated. The comparison between the calculated and experimental results verified the validity of the mathematical model and analytical method.
