多种通信技术在大型垃圾焚烧发电厂中的应用

Application of multifarious protocols in large-scale waste incineration power plants

为了解决大型垃圾焚烧发电厂工艺子系统类型较多、监控点数量较大、分布较分散的问题,对制约工艺子系统集中监控的因素进行了分析,结合工程实例,提出了采用OPC、Profibus DP、Modbus、西门子S7等多种通信协议的方案,实现了工艺子系统与DCS的无缝连接,提高了垃圾焚烧发电厂的自动化监控水平。

To solve such problems as multiple types of subsystems,large number of monitoring sites and dis-persed distributions occurred in large-scale waste incineration plants,the factors restricting the process subsystem centralized monitoring were analyzed.Moreover,combining with the engineering example,the application of OPC,Profibus DP,Modbus,Siemens S7 communication protocols and other protocols were proposed to achieve a seamless connection between the subsystems and DCS,which improved the overall waste incineration plant automation control level.
