Embodiment
[0080] The hydraulic turbine speed regulation system includes the controller, the electro-hydraulic servo system, the water passing system, the water turbine, the generator and the load; among them, the electro-hydraulic servo system, the water passing system, the water turbine, the generator and the load constitute the controlled object. In this embodiment, for the water system, a one-dimensional transient flow characteristic line method is used to construct a one-dimensional water system model; for a water turbine, a three-dimensional water turbine internal flow model is constructed using computational fluid dynamics (CFD); The piping system made up of other components uses the existing 1D model.
[0081] like Figure 5 As shown, the optimization method of this embodiment is a multi-objective particle swarm optimization method, and the particle swarm optimization method is specifically as follows:
[0082] (1) Algorithm initialization;
[0083] Set algorithm parameters, in...
