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 drawings in the description figure 1 , figure 1 It is a structural diagram of the 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 acceptable for the safe operation of the unit. s . The main controller of the machine furnace selects the load control method that meets the operating requirements of the unit, and accepts the actual load command N s , active power N, main steam pressure given value P s and main steam pressure P T Signal and generate steam turbine command (TD) and boiler command (BD), which are sent to steam turbine and boiler control system respectively. The combustion control system of the boiler changes the combustion rate by adjustin...
