SUPERCRITICAL PRESSURE POWER PLANT AND VARIABLE PRESSURE OPERATION CONTROL METHOD THEREOF

摘要

The present invention discloses a supercritical pressure power generation plant and a method of controlling a variable pressure operation thereof. A method for controlling a variable pressure operation of a supercritical pressure power plant according to the present invention includes the steps of: a controller driving a fluidized bed boiler by receiving a target load amount from an upper controller; Receiving a power generation load after the control unit drives the fluidized bed boiler; And performing the constant voltage operation when the power generation load to which the control unit is input is in the transforming operation from the first set generation load or more to less than the second set generation load and is greater than the second set generation load.
