Abstract
The invention relates to the technical field of flexible alternating current control, in particular to a gear optimization control method, device and equipment for a phase shifter and a medium, and the method comprises the steps: setting reference power, and calculating real-time active power; entering a closed-loop control mode, and inputting the deviation between the real-time active power and the reference power into a PI controller to generate a continuous gear signal; the continuous gear signal is converted into a discrete gear signal, and a signal closest to the reference power is selected; a phase shifter is driven to adjust a shunt transformer tap, and the real-time active power of the line is adjusted; if the deviation exceeds a preset threshold value, closed-loop control mode adjustment is kept; if the deviation is within a threshold value, entering a gear tentative mode, judging a power change trend, if the trend is opposite, switching to an open-loop mode, clearing the error of the PI controller, and storing the current gear as a reference gear; the deviation value is recorded by adjusting the reference gear, the gear with the minimum deviation is selected as the optimal gear, optimization control is completed, and the line transmission efficiency is improved.
