摘　　要：为实现煤粉锅炉发电机组深度调峰的安全稳定运行,该文回顾国外调峰技术的发展历程,分析国内各种调峰技术路线的发展现状以及存在的问题,并预测未来调峰技术的发展方向。国内深度调峰运行策略集中于机组燃烧侧的低负荷运行、热电联产机组的热电解耦、储能耦合调峰以及快速变负荷响应等领域。针对不同的机组类型和调峰需求,应当综合考虑多方面因素,包括调峰效果、技术可靠性和运行经济性等指标,从中选择恰当的改造路线。未来,增加灵活调节电源装机比例、开展锅炉燃烧侧预热调峰技术改造、利用先进储能技术耦合调峰等方式参与机组的深度调峰运行将有很大的应用前景。To realize the safe and stable operation of deep peak shaving of pulverized coal-fired boiler power units,this review reviews the development history of foreign peak shaving technology,analyzes the current situation and existing problems of various domestic technical routes,and forecasts the development direction of peak shaving technology in the future.The domestic deep peak shaving operation strategies focus on the low load operation on the combustion side of the unit,thermoelectric decoupling of cogeneration unit,energy storage coupling peak shaving and fast load change response.In terms of different unit types and peak shaving needs,many factors,including peak regulation effect,technical reliability and operation economy should be comprehensively considered.Afterwards,the proper retrofit route could be obtained.In the future,increasing the installed proportion of the power supply that could be adjusted flexibly,launching the transformation of the preheating peak shaving technology on the combustion side of the unit and utilizing the advanced energy storage technology coupling peak shaving to realize the deep peak shaving operation of the unit will have a great application prospect.
