摘要
文章给出了作者所采用的水轮机综合特性曲线的数值化工作的基本原理及几个实例,并就作者建立的一维管道瞬态流计算,混流式水轮机调保计算,以及小波动过程的动态模拟等程序的工作原理和功能进行了介绍,还提供了几个计算结果作为例证。
This paper aims at giving a brief account of the work on the development of a numeric model of transient process of a hydraulic power plant with francis turbines. Firstly, a new method is presented, which is used in digitization of the turbine's comprehensive characteristic curves. Results obtained by this method are also given. Then, both basic principle and function of several numerical models that we have developed are introduced, these include a numerical model of One-D transient tube flow, one about francis turbines guaranteed calculation for regulation, and another on dynamic simulation for small surge caused by regulation. Some calculation results are used as examples.
