, PP. 61-69
Keywords: 燃煤发电过程,可控参数,汽轮机热耗率,锅炉效率,局部动态模型,运行性能评价
Abstract:
针对燃煤发电过程中复杂过程优化运行问题，提出了基于运行性能评价的燃煤发电运行可控参数优化方法。在分析燃煤发电过程工艺和机理的基础上，采用基于即时学习策略的局部建模方法建立了汽轮机热耗率、锅炉效率局部动态模型；运用模糊综合评价方法对机组运行性能进行综合评价，根据当前运行边界条件和综合评价等级，采用案例推理方法获得机组较优运行性能下可控参数的优化目标值，基于优化目标值的评价对可控参数进行闭环优化设定。基于工业运行数据的仿真结果表明，该方法可有效提高机组运行性能，较好地解决了燃煤发电过程的优化运行问题。
