Under the"dual carbon target",the function of thermal power plants has gradually shifted from being the main power supplier to being the regulating and coordinating party,and their output range is a key indicator of regulating capacity.The calorific value of coal has an important impact on the output range of thermal power units.In the past,coal quality detection mainly relied on coal quality report anal-ysis,but this method lacked real-time and convenience.To address this issue,we propose a method for monitoring coal quality changes based on operating data of thermal power units,and validate the proposed method with the actual reported low calorific value of coal quality.Finally,we calculated the impact of coal quality changes on the output range of the unit.
