摘要：
以派克方程为基础，分别建立了同步汽轮发电机和异步化汽轮发电机考虑等效阻尼绕组作用的单机无穷大系统线性化数学模型。利用所建模型，对考虑等效阻尼绕组作用的同步汽轮发电机的开环阻尼特性进行了分析；在此基础上，同时对异步化汽轮发电机的开环阻尼特性进行分析；并对异步化汽轮发电机和同步汽轮发电机的开环阻尼特性进行比较研究。通过比较，阐述了异步化汽轮发电机的开环阻尼特性与电机参数、系统参数以及运行状态的关系，展示了异步化汽轮发电机在提高电力系统稳定性方面较同步汽轮发电机的优势，进一步完善了异步化汽轮发电机的研究理论。 |

Abstract:
Based on the Park equation, one-machine infinite-bus system linearized models of asynchronized turbo-generators and synchronous turbo-generators were established respectively considering the effect of equivalent damper windings. Comparative analysis on the open looped damping characteristics of asynchronized turbo-generators and synchronous turbo-generators was done and the relations between the open looped damping characteristics of asynchronized turbo-generators and the generator parameters, power grid parameters, operation conditions were demonstrated. The conclusions show that asynchronized turbo-generators have advantages in improving the power system stability compared to synchronous turbo-generators. The theory on asynchronized turbo-generators is further enriched. |
