Embodiment Construction
[0141] Embodiments of the present invention: a method for automatically adjusting the active power output of wind turbines in a wind farm, detecting the bus frequency of the converging point in the wind farm, and feeding back the detected data to the input end of the active power comparison link of the control system of each wind turbine, so that the feedback The bus frequency of the converging point is used as an active additional signal, and the original active power setting value is corrected to obtain a new active power setting value. According to the new active power setting value, the active power of each fan is adjusted in real time through the double closed-loop control system. output, so as to realize the automatic and synchronous adjustment of the whole wind farm.
[0142] feedback to each Typhoon The feedback delay of the bus frequency at the converging point is required to be less than the calculated value obtained according to formula (C-5),
