超临界660MW空冷机组供热期变负荷性能的综合提升与改善

相比常规机组,大型空冷机组在供热期的变负荷能力更需要提升和改善。由于火电机组深度快速变负荷性能综合优化的具有受多因素影响和涉及多学科知识的特点。因此,当前的大部分研究工作都围绕单个层面的策略进行,而从跨学科、多视角对火电机组进行全局优化的有非常大的实际应用价值的公开研究成果详细介绍较少。本文从多个角度对设备进行优化,构建机组重要参数监测系统,实际2台超临界660MW空冷机组的优化实例显示:供热期的综合优化策略不仅需要优化多项内容,而且还需要注意整体实施次序。

Compared with conventional units, the variable load capacity of large air-cooled units during the heating period needs to be improved and improved. However, the comprehensive optimization of deep and variable load performance of thermal power units is inf luenced by many factors and involves multidisciplinary knowledge. Therefore, most of the current research work is carried out around a single strategy, and the public research results with great practical application value from the interdisciplinary and multi-perspective global optimization of thermal power units are less detailed. This paper optimizes the equipment from multiple angles and constructs the important parameter monitoring system of the unit. The examples of two supercritical 660MW air-cooled units show that the comprehensive optimization strategy in the heating period not only needs to optimize multiple contents, but also needs to pay attention to the whole Implementation order.
