The invention discloses a controller oscillation divergence control method, a controller and a storage medium, and the controller oscillation divergence control method comprises the steps: collectinga first controlled variable value in real time in a preset adjustment period, and obtaining a positive deviation value and a negative deviation value through calculation according to the first controlled variable value and a preset stable value; judging whether the positive deviation value and the negative deviation value meet a preset rule or not; if the positive deviation value and the negativedeviation value accord with the preset rule, determining that an oscillation phenomenon occurs; calculating to obtain an instruction mean value according to a control instruction parameters sent to external equipment, and calculating to obtain an instruction error according to the instruction mean value and a preset instruction value; judging whether the absolute value of the instruction error issmaller than a preset dead zone width or not; and if the absolute value of the instruction error is smaller than the preset dead zone width, entering a manual mode for operation. According to the invention, the manual adjustment can be realized when the oscillation divergence phenomenon of the controller cannot be automatically adjusted.
Description
technical field [0001] The invention relates to the technical field of automatic control of thermal power plants, in particular to a controller oscillation divergence control method, a controller and a storage medium. Background technique [0002] At present, the national power industry is developing faster and faster, and the level of automation is getting higher and higher. DCS control has been widely used in various thermal power plants. The automatic control system in DCS generally adopts the conventional PID control strategy. In general, the control system can achieve a better adjustment effect through automatic adjustment of the setting parameters. However, if the parameter setting is strong, or when a large disturbance occurs, the phenomenon of oscillation divergence cannot be automatically adjusted by setting the parameters. [0003] Therefore, it is necessary to provide a controller oscillation divergence control method to solve the above technical problems. [00...
