摘要
通过分析传统水轮机建模的不足,提出了用Matlab中的S函数建立水轮机非线性动态模型的新方法.给出了应用于某电站水轮机数字建模的具体实例.由于新方法是直接对水轮机全特性曲线进行处理,因而具有比传统方法更高的精度和可信度,这对研究水轮机动态特性和调速器PID参数的离线优化有重要意义.
Disadvantages of the conventional method of turbine modeling are first put forward. Then, a new method of using S function in Matlab to construct the turbine model is proposed. Compared with the conventional method, the new one has higher credits and is more accurate. It is of high significance to research the dynamic performance of hydro turbine and the off-line optimization of PID parameters of governor.
