摘要
介绍了一种在MATLAB/SIMULINK环境下根据ITAE指标对水轮机调节系统实施寻优的新方法。该方法通过M文件修改调节器参数并调用水轮机调节系统的SIMULINK模型在该参数下进行仿真计算得到对应过渡过程的ITAE指标值,最后根据最小化原则对这些指标值进行比较从而得到最优的调节器参数。结合了M文件编程调试方便和SIMULINK易于构建复杂模型的优点,并具有模块化的设计特征,其中水轮机调节系统的SIMULINK模型具有很强的开放性和可移植性,能够适应水电机组的特点。仿真实验表明M文件和SIMULINK的交互式仿真,是灵活有效的。
A new method for optimizing governing parameters of hydro-turbine governing system based on integral performance criteria （ITAE） under the environment of MATLAB/SIMULINK is introduced in this paper. The method can identify the governing parameters through modifying M-file, simulate the hydro-turbine governing system to obtain the corresponding ITAE indexes of the transient process through calling the model SIMULINK using the parameters identified, and compare the indexes to find the optimal governing parameters according to the minimum value of ITAE. The system incorporates the convenient debug of M-file, and easy to construct complicated model of SIMULINK with the characteristics of modularization. The model SIMULINK is open and transformable, so it is suited for other hydraulic power stations. The simulation results indicate that interactive simulation between MATLAB and SIMULINK is flexible and effective.
