Abstract

The invention relates to a method and a device for setting parameters of a closed-loop PID (proportion integration differentiation) controller of a gas turbine. The method comprises the following steps of initializing the initial values of a proportion action coefficient and an integration action coefficient of the PID controller, and researching the step length; determining the researching ranges of the proportion action coefficient and the integration action coefficient; performing the step response testing of a gas turbine model on all combinations of searching values of the proportion action coefficient and the integration action coefficient within the searching range, and selecting all searching values meeting the maximum overshoot and time adjusting requirements; determining one group of setting parameters. The method has the advantages that the defects of low parameter setting effect and poor control effect because of reliance on experiences of engineers in the prior art are overcome; a plurality of controller parameters meeting the dynamic property indexes of the controller can be automatically obtained, the setting parameters are determined, the control effect better than the effect of the manual setting method is obtained, the service life of the gas turbine unit is effectively prolonged, and the fuel consumption of the gas turbine unit is decreased.

Description

technical field [0001] The invention relates to the technical field of gas turbine control, in particular to a parameter setting method and device for a gas turbine closed-loop PID controller (Proportion Integration Differentiation, proportional-integral-differential controller). Background technique [0002] The working process of a heavy-duty gas turbine for power generation is that the air is compressed in the compressor, mixed with the fuel injected in the combustion chamber for combustion, and the high-temperature combustion gas expands in the turbine to do work, driving the generator to be connected to the grid for power generation. The heavy-duty gas turbine is a multivariable nonlinear coupling system. The common control system adopts segmental control, which is similar to an expert control system, including: start-up control in the start-up process, speed control in the load process, and close to Use temperature control at base load, etc. The control objectives and...
