method for calculating the real-time maximum adjustable load for thermal power units was presented.Through analysis on related operation parameters such as pulverizing system capacity
heating surface temperature
main steam pressure
feedwater flow rate
turbine vibration and auxiliary equipment performance
this method can ascertain the real-time maximum adjustable unit load.According to the relativity between the maximum adjustable loads during different periods and the unit parameters at the same period
the obtained unit load margin not only can guide the operation optimization
but also can help the power grid regulate the unit load in time.
