| 摘 要： | 本文从派克方程出发,利用修正的派克变换,列写了发电机组的状态方程,用TQ-16电子计算机研究了发电机失磁进入稳定异步运行,然后投入励磁再同期全过程。研究了励磁绕组的灭磁电阻阻值大小对于异步运行过程的影响,得出了相应的结论。计算了异步运行时转子各绕组损耗的分布。在再同期的研究部分研究了投励角δ_i对于发电机拉入同期过程的影响,仔细研究了励磁电压高低和异步转矩大小对于拉入同期过程的影响。

A Computer-aided Stuuy of the Asynchronous Operation and the Resynchronzation Process of Synchronous Machines |
| |
| Abstract: | In this paper the state equations of a synchronous machine set are derived from Park's Equation by using modified. Park's transformation. The whole process of the stable asynchronous operation mode of the generator after lossing excitation and its resynchronization after shooting excitation are culculated by computer TQ-16. The effect of the value of field resistance on the process of the stable asynchronous operation mode is studied and the relavant conclusions are reached. The power loss distribution in rotor windings are computed. In the part of resynchronization study of the paper, the effects of factors, such as the angle δi where the excitation was closed, the value of field voltage and asynchronous torque, onthe process of pulling the machine into synchronous operation are studed in detail. |
