[0017] detailed description: The present invention will be further described below in conjunction with accompanying drawing:
[0018] Such as figure 1 As shown, the present invention provides a direct energy balance strategy feedforward control method. On the basis of the direct energy balance control strategy, the method uses the feedforward control technology to speed up the response of the boiler to the demand of the steam turbine according to the energy signal. When using the direct energy balance control strategy In the coordinated control mode, the boiler uses the boiler main control command to directly control the input heat of the boiler with the energy demand of the steam turbine to adjust the deviation between the energy demand signal of the steam turbine and the heat signal.
[0019] The method for forming the main control command of the boiler is as follows: use the ratio of the first-stage pressure 1 of the steam turbine to the pre-machine pressure 5 to obtain ...
