炉膛压力控制是火力发电厂燃烧控制系统的一个重要组成部分,炉膛压力的稳定与否直接关系到机组运行的安全性与经济性。针对炉膛压力单回路调节系统,参考了国内外一些600MW燃煤发电机组的控制策略,提出了炉膛压力测量回路的信号处理模型,对如何进行压力测量信号的采集处理以减少系统波动的方法进行了详细的研究分析。
Furnace pressure control is an important part of combustion control system of thermal power plant. The stability of furnace pressure is directly related to the safety and economy of unit operation. Aiming at the single-loop pressure regulating system of furnace hearth, the control strategies of some 600MW coal-fired generating units at home and abroad are referenced. The signal processing model of hearth pressure measuring circuit is put forward. How to collect and process the pressure measuring signals to reduce the system fluctuation Detailed research analysis.
