Online Modeling and Simulation Algorithms Analysis Used on Water Turbine System

Abstract:

Water turbine system model is set up in MATLAB based on the three main parameters which are guide vane opening, unit flow and unit speed. Then use trainlm function and sample defaulted by the system to train the networks. The interpolation fitting process of the nonlinear relation is performed on the PC and only the right value and threshold of the non-linear relationship are transferred to the control core DSC of the local computer, which effectively improved the nonlinear real-time simulation speed. The process of realizing the nonlinear simulation based on neural network according to the actual unit HL220 is discussed and analyzed the results.
