垃圾填埋气发电中自动控制系统的研究

Automatic Control System's Research in Landfill LFG to Energy

根据垃圾填埋气发电的要求,采用西门子的可编程逻辑控制器和艾默生的集散控制系统来实现工艺过程的控制。工程实践证明,利用PLC和DCS控制的垃圾填埋气发电系统,结合本文设计的控制算法,简化了控制系统的设备和结构,同时实现了节能降耗和系统的可靠运行。

According to the requirements of the landfill LFG to energy,we use programmable logic controller of Siemens and distributed control system of Emerson to achieve the control process.Project proved that the use of LC and DCS in landfill LFG to energy system,with the control algorithm designed in this paper,simplifies equipment and structures of the control system,while achieving the energy saving and reliable operation of the system.
