采用国际上通用的工程计算软件MATLAB及可视化仿真工具SIMULINK,构建了某水电站1号机组调节系统的完整动态仿真模型。其中,针对水轮机的非线性特性,利用MATLAB神经网络工具箱,对水轮机综合特性曲线建立了RBF网络非线性数学模型。所建立的仿真系统具有很强的开放性和可移植性,能够适应水电机组的特点。仿真实验表明该软件确实给水轮机调节系统的仿真提供了强有力的分析手段。
Using the internationally accepted engineering calculation software MATLAB and visual simulation tool SIMULINK, a complete dynamic simulation model of the regulation system of Unit 1 in a hydropower station was constructed. In view of the non-linear characteristic of hydraulic turbine, a non-linear mathematical model of RBF network is established for the comprehensive characteristic curve of hydro-turbine by using MATLAB neural network toolbox. The established simulation system has a strong openness and portability, can adapt to the characteristics of hydropower units. Simulation experiments show that the software does provide a powerful analytical tool for the simulation of turbine governing system.
