Embodiment Construction
[0049]Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0050] like figure 1 As shown, in the first aspect of this embodiment, a method for generating an adaptive load variable command based on the thermal inertia of a coal-fired power station is provided, including:
[0051] S100. Determine the target load in response to the received load changing instruction;
[0052] S200, obtaining the initial load of the coal-fired power station;
[0053] S300. Calculate the current load increment of the coal-fired power station according to the load increment function, where the load increment function is an S-curve function with time as the horizontal axis and load increment as the vertical axis;
[0054] S400. Generate a lo...
