摘要
传统PLC加工控机的控制虽然能够实现每个火电厂辅助子系统的运行,但暴露出管理分散、备件种类多、设备投资大及通信网络复杂等缺陷。针对上述问题,集计算机、数据库、可编程序逻辑控制器、Ethernet网络和自动化技术为一体的发电厂辅网集中监控(BoP)系统成为电力工业自动化发展的新趋势和研究方向。辅控网能有效降低发电厂运行和维修成本,提高系统的安全性和可靠性,为管理人员及时全面掌握电厂辅助系统的运行状况提供了监控平台。
Although the operation of the auxiliary subsystems in fossil fired power plants can be implemented by traditional combination of PLC＋IPC,many defects still being found,e.g.decentralized management,various spare parts,large investment in equipment,and complex communication networks,etc.;thus balance of plant（BoP） system that combining technologies of computer,database,programmable logic controller,Ethernet network,and automation become new trend and research orientation for process automation of electric power industry.The BoP system effectively reduces operational and maintenance costs of the plant,and enhances security and reliability of the system,it provides a monitoring platform to management personnel for mastering comprehensive operation status of all the auxiliary subsystems in the plant.
