Embodiment Construction
[0086] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0087] Please refer to the accompanying drawings in the figure 1 , figure 1 It is a structural diagram of unit unit load control involved in the present invention. When the external load request command arrives, the load command processing circuit will select and process it to convert it into the actual load command N that can be accepted by the safe operation of the unit unit s . The main controller of the furnace selects the load control mode that meets the operating requirements of the unit, and accepts the actual load commandN s , active power N, main steam pressure given value P s and main steam pressure P T Signal and generate turbine order (TD) and boiler order (BD) respectively sent to the steam turbine and boiler control system. The combustion control system of the boiler changes the combustion rate by adjusting the amount of fu...
