Direct energy balance coordinate control system for thermal power generation unit

The invention provides a direct energy balance coordinate control system for a thermal power generation unit. The direct energy balance coordinate control system for the thermal power generation unit comprises a first PID adjusting module, a second PID adjusting module, a first adding and subtracting module, a second adding and subtracting module, a third adding and subtracting module, a first addition module, a second addition module, a third addition module, a division module, a first multiplication module, a second multiplication module, a first differential module, a second differential module and a dead zone non-linear module. According to the direct energy balance coordinate control system for the thermal power generation unit, the problem that load adaptability and operation stability a large thermal power generation unit are contradictory is solved, rapidness and stability are achieved, a boiler is fully used for storing energy in the load changing process, fast responses to load changes are achieved, the amplitude of using the boiler to store energy is correspondingly limited, meanwhile, energy input of the boiler is dynamically overshot, stored energy is made up for, and the vapor pressure is stabilized.
