PID (Proportion Integration Differentiation) setting method and device of oil and gas pipeline pressure regulating equipment

The embodiment of the invention discloses a PID setting method and device for oil and gas pipeline pressure regulating equipment, and belongs to the technical field of industrial automation control. The method comprises the following steps: acquiring a plurality of simulated flows of a target oil and gas pipeline, and modeling the target oil and gas pipeline and a pressure regulating valve, a variable frequency pump, a compressor, a frequency converter and a pressure detection meter arranged on the target oil and gas pipeline to obtain a pipeline transportation model; determining a first PID theoretical parameter corresponding to the pressure regulating valve; performing simulation under the condition that the flow of the pipeline transportation model is the residual simulation flow except the first simulation flow in the plurality of simulation flows, so as to determine a first PID (Proportion Integration Differentiation) correction parameter; and controlling a pressure regulating valve on the target oil and
