Abstract

The invention discloses a dynamic surface control method for the opening of a main throttle valve of a steam turbine generator. The method comprises the following steps of: 1, analyzing a main throttle valve opening control system model, and constructing; 2, performing dynamic surface control and design on the opening of the main throttle valve of the steam turbine generator; 3, inspecting tracking performance, and adjusting parameters; and 4, finishing the design. The dynamic surface control method for the opening of the main throttle valve of the steam turbine generator is provided for the main throttle valve opening control system model, so that a preset track can be quickly and accurately tracked by the power angle of the steam turbine generator of a closed-loop system on the basis of ensuring the stability of a closed-loop semi-global system. The method has high practical value and a wide application prospect in the technical field of automatic control.

Description

(1) Technical field [0001] The invention relates to a dynamic surface control method of the main steam valve opening of a turbogenerator, which is aimed at a single machine infinite bus system, and provides a dynamic surface control method of the main steam valve opening of a turbogenerator, which is used for controlling The utility model relates to a power angle of a steam turbine generator, which belongs to the technical field of automatic control. (2) Background technology [0002] Excitation control and steam valve adjustment of turbogenerator are two important means to improve the stability of power system. Sun Liying's doctoral thesis "Nonlinear Robust Adaptive Control Design of Power System Based on Backstepping Method" pointed out that since the excitation control is limited by the top value of the excitation current, requiring the generator to have an excessively high top value of the excitation current will increase the generator's Manufacturing cost; at the same ...
