摘　　要：华能长兴电厂在燃煤机组深度调峰方面进行了诸多有益尝试,自主开展30%额定负荷深度调峰试验,试验中暴露出汽泵协调控制、脱硝系统运行、锅炉稳定燃烧、风机失速、再热汽温控制等方面的问题,对这些问题进行了深入分析并制定了对策。重点对华能长兴电厂660 MW超超临界机组30%额定负荷深度调峰方面进行了研究,该技术在类似发电机组中的推广应用具有一定的借鉴意义。Huaneng Changxing Power Plant has made many beneficial attempts in the deep peak regulation of coal-fired units.During the independently conducted deep peak load reguation test of 30%rated load,some problems occurred in steam/pump coordinated control,denitration system operation,boiler stable combustion,fan stalling,reheat steam temperature control,et al.The problems were thoroughly analyzed and the countermeasures were proposed.The 30%rated load deep peak regulation of 660 MW ultra-supercritical units in Huaneng Changxing Power Plant is emphatically studied,which can be used as reference for the application of similar power generation units.
