Research and Application of Key Technologies for Flexible Operation and Deep Peak Shaving of Thermal Power Units
In recent years,the installed capacity of wind and photovoltaic power in China has grown rapidly,and some regions have experienced serious problems of wind,solar,and water abandonment.By renovating coal-fired power units and unleashing their potential flexibility,the regulation capacity of China's power system can be effectively improved.The article combines the equipment and operating conditions of power plant units to propose technical solutions for the comprehensive application of external flue gas bypass transformation of economizers,separator and distributor transformation of coal mills,rapid start stop system of steam turbines,and online measurement and regulation device transformation of air and powder.At the same time,a feasibility analysis of the technical solutions is carried out to ensure that the units can operate safely and stably at 20-30%rated load.
