Description

technical field [0001] The invention relates to the field of hydraulic turbine simulation, in particular to a real-time simulation method, device and electronic equipment of a hydraulic turbine regulation system based on the improved characteristic line method. Background technique [0002] The characteristic line method is currently the most commonly used method for solving the hydraulic transient process of the piping system of the turbine regulating system. Its advantages mainly include: the stability criterion can be established; the boundary conditions are easy to program; it can be applied to the hydraulic transient analysis of various pipelines . Therefore, it is the one with better precision among all discrete algorithms. The basic characteristic line method can show the properties of elastic water hammer, but the elastic water hammer decays slowly, the damping is small, and the convergence is poor, especially after the water flow is cut off. The real-time simulatio...
