本文研究与当地电网连接的水力发电机组速度控制系统的设计。手工设计方法仅限于很简单的对象模型,如果按常规需要更适当的模型时,一个控制系统的交互式计算机辅助设计过程则是必要的。它包括用高效率的频率域方法离线地求出调速器适应参数和形成一个两级的前馈自调整速度控制系统。
This paper studies the design of hydro-generator speed control system connected with local power grid. Manual design methods are limited to very simple object models and an interactive computer-aided design process for a control system is necessary if a more appropriate model is routinely required. It involves obtaining the governor adaptation parameters off-line using an efficient frequency-domain approach and forming a two-stage feedforward self-tuning speed control system.
