摘要
介绍了锁相环技术用于直流电动机 (动模发电机的原动机 )调速与调速系统模拟的方法及其相关技术 ,即同步相位的选择方法以及转速的开环调节与闭环比例积分调节的无扰切换。并且给出了水轮机调速系统的阶跃响应和正弦响应实验结果。实验结果表明该系统结构简单、灵活 ,转速调节平稳 ,完善了动模水轮机或汽轮机调速系统的动态模拟 ,为在调速系统研究发电机的稳定控制方法奠定了良好的基础。
The method and technique are introduced for speed regulation and governing system simulation of dynamic simulating generator by using PLL. It includes the method for selecting the synchronous signal and exchanging control laws between open-loop adjustment and PI close-loop adjustment. A hydro-turbine model is simulated by the SISO control system. The response test of the unit was done with the input signal of pulse and sine wave. The results of the test show that the structure of the system is simple and suitable to simulate different governing systems.
