摘要

为提高供热机组的调峰性能，提出了一种集成切缸、高中低压旁路供热、热泵、热水罐和电锅炉5种热电解耦技术的新型二次再热供热机组流程，构建了详细的热力学分析模型，对比分析了参比电厂与新型电厂的调峰性能，依托电力现货市场，提出了系统的经济运行策略，并开展了技术经济性评估。结果表明：当供热需求为1 460 MW时，参比电厂在抽凝工况下无法满足供热需求，在切缸工况下，参比电厂的负荷调节范围为额定负荷的77.9%～80.0%，几乎丧失了负荷调节能力，而在切缸+旁路工况下，参比电厂的负荷调节范围为50.0%～80.0%，调峰能力有所改善；对于新型电厂，在相同的供热需求下，负荷调节范围扩增至0～80.0%，尤其是在电力低谷期可实现零功率上网；与参比机组相比，新型机组每月可减少低谷期上网电量约10.76万MW·h，节省燃煤量约1.77万吨，每年在采暖季可增加净收益约6 898.8万元，新增设备投资回收期约5.6年，经济效益显著。
