水轮机调节系统的多帧速仿真算法研究

Study on Digital Simulation of Hydraulic Turbine Governing System Using Multirate Integration Techniques

针对水轮机调节系统各环节时间常数相差甚远(以至呈现明显的病态性)的特点,提出用多帧速仿真算法对水轮机调节系统的过渡过程进行数字仿真,大大减少计算次数,较好地解决了数字仿真的实时性与计算稳定性的矛盾,获得了令人满意的仿真结果。

Because hydraulic turbing governing system consists of widely different time constant units, author proposes that simulating dynamic process of the system using multirate integration techniques. Not only computing,times are greatly reduced,but also the contradiction between real - timelity and computing stability in digital simulation are resolved,simulation result is satisfactory.
