Abstract

The embodiment of the invention provides a method for optimizing air-borne PID parameters of a mixed-flow hydro-generator governor, and relates to the technical field of intelligent optimization control. The method comprises the following steps that an initialization population is randomly generated, an initial temperature T0 and a final temperature T1 are determined, and the initialization population comprises a plurality of sets of PID parameters; the population is subjected to iterative optimization by using an improved teaching and learning algorithm; and a set of PID parameters with the minimum evaluation index are selected from the population which is subjected to the iterative optimization to be an optimal PID parameter. According to the method for optimizing the air-borne PID parameters of the mixed-flow hydro-generator governor, an air-borne PID disturbance mathematical model and an ITLBO optimization method of a mixed-flow hydro-generator speed regulation system are provided,so that the expression of the PID parameter optimization process is clearer, the optimization result is more trusted, and after the optimized PID parameters are used, the stability of a hydro-generator unit in the operation process is facilitated.

Description

Technical field [0001] This application relates to the technical field of intelligent optimization control, and in particular to a method for optimizing no-load PID parameters of a Francis hydro-generator governor. Background technique [0002] For Francis hydro-generator, the no-load PID (Proportion Integration Differentiation) parameter of the hydro-generator governor is mainly used to control the guide vane of the hydro-generator unit under no-load operation. So that the unit frequency can be stabilized within a certain range, and the no-load PID parameters of the governor (including K P , K I , K D And bp, etc.) is directly related to the quality of PID regulation. [0003] At present, the no-load PID parameters of the Francis hydro-generator governor are usually set and optimized by power testers through the no-load frequency disturbance and no-load frequency swing tests of the on-site speed control system. Specifically, in the process of optimizing PID parameters, power test...
