摘　　要：介绍了由锁相环（ＰＬＬ）、可编程逻辑器件（ＰＬＤ）和单片机（８０Ｃ１９６）组成的水轮发电机组调速模 拟装置的原理。利用锁相环实现了可控硅触发脉冲自动跟踪电网频率和相位波动；利用可编程逻辑器件实 现了故障类型判断和故障报警；利用单片机完成水轮机模型的动态仿真和参数设定。利用该装置进行了水 轮机响应特性动模实验。The simulation device and speed regulating of hydro-turbine generator by using phase-locked loop (PLL) and programmable logical device (PLD) are introduced. Trigger angle of SCR is kept synchronous with voltage of power source by PLL. PLD is used to select and indicate faults. The hydro-turbine model is simulated by the SISO control system. The response test of the unit has been done with the input pulse signal.
