Method, device and storage medium for improving low frequency disturbance passage rate for thermo power plants

The present invention relates to the technical field of thermo power plant control, and is a method, apparatus and storage medium for improving low frequency disturbance passage rate for thermo power plants, comprising: responding to that the actual revolution rate of the power plant is no less than 2999 r/min and no more than 3001 r/min, or no less than 3002 r/min, selecting a maXimum value of the revolution rate, and obtaining a corresponding frequency regulation load setting value based on the low frequency disturbance difference rate, in response to that the actual revolution rate of the power plant is no more than 2998 r/min, selecting a minimum value of the revolution rate, and obtaining the corresponding frequency regulation load setting value based on the low frequency disturbance difference rate of the power plant. In the present invention, by executing the power plant frequency regulation load setting and the power plant frequency regulation power setting, the actual load of the power plant can reach the frequency regulation load setting value each time after low frequency disturbance and indicators of primary frequency regulation outputting response passage rate and primary frequency regulation contributed power can be promised.
