| 摘要: |
| 通过分析舰船电力系统暂态稳定性的特点，并结合陆地电力系统暂态稳定性分析的理论，提出了适用于舰船电力系统暂态稳定性分析的发电机六阶数学模型、电动机二阶动态模型和恒功率静态模型相结合的综合负荷模型，以及具体的分析步骤。在舰船电力系统暂态稳定性分析中采用了适用于舰船电力系统暂态稳定的判据，并同时考虑了原动机、调速器和励磁器的动态变化。针对实例，在正常运行方式下，考虑严重故障、运行方式切换以及大型电动机启动对舰船电力系统暂态稳定性的影响进行了分析研究。仿真分析验证了所建立的数学模型以及采用的分析方法的正确性。 |

| Abstract: |
| The characteristics of warship power system transient stability are analyzed and combined with the theory of land power system transient stability analysis，the models suitable for shipboard power system transient stability analysis are put forward，such as the six-order generator mathematical model，the comprehensive load model including two-order motor dynamic model and constant power static model. Corresponding analysis steps are provided. The criterion suitable for shipboard power system transient stability analysis is adopted and the dynamics of prime mover，governor and exciter are considered. The influences of serious fault，operation mode switchover and large motor starting in normal operation on shipboard power system transient stability are researched with cases. Simulation verifies the correctness of the proposed mathematical model and the analytic method. |
