【摘要】 在水电站水力过渡过程计算中,水轮机边界条件通常利用水轮机特性曲线近似描述。针对水轮机特性难以用解析式表达的问题,利用MATLAB强大的数据处理功能,将水轮机模型综合特性曲线处理成空间曲面,并在此曲面中进行插值。计算实例说明了该方法的有效性和实用性。
【Abstract】 During the course of hydro-power station hydraulic transient computation,the turbine boundary conditions are depicted by the turbine characteristic curve. To the problem that the turbine characteristics is difficult to describe by mathematic analysis functions, this paper devised a new method by which we transfer the turbine modal complex characteristic curve into a spatial curved surface, and set the interpolation in the surface, based on the MATLAB’s powerful dataprocessing function. The computational cases prove that the method is practical and effective.
