摘要
为探究超大型城市燃气电厂在新能源快速发展背景下的应对策略与发展路径,本文以北京燃气电厂为研究对象,聚焦其面临的电网适应性挑战与调峰经济性竞争,深入剖析相关技术的应用效果。研究表明:燃机进气温度调节技术可有效提升夏季顶峰发电能力;蒸汽分流技术可显著扩展机组调峰运行范围;烟气余热利用可大幅拓展供热能力并提升机组热效率。据此提出,燃气电厂亟需通过上述热电解耦或灵活性增强技术向调峰角色转型,从而在新型能源体系中确立经济竞争力。
To explore the coping strategies and development paths of gas-fired power plants in super-large cities against the backdrop of the rapid development of new energy,this paper takes Beijing's gas-fired power plants as the research object,focusing on the challenges of grid adaptability and the economic competition in peak-shaving they face,and conducts an in-depth analysis of the application effects of relevant technologies.The research shows that the gas turbine inlet temperature regulation technology can effectively improve the peak power generation capacity in summer;the steam diversion technology can significantly expand the peak-shaving operation range of the units;the utilization of flue gas waste heat can greatly expand the heating capacity and improve the thermal efficiency of the units.Therefore,it is proposed that gas-fired power plants urgently need to transform into peak-shaving roles through the above-mentioned thermal-electric decoupling or flexibility-enhancing technologies to establish economic competitiveness in the new energy system.
