摘要
现场总线是用于现场仪表与控制系统和控制室之间的一种串行、全分散、全数字化、智能、双向、多变量、多点、多站的通信系统。随着发电厂单机容量的增加和电厂设备分散化、数字化、网络化、智能化的发展,发电厂电气控制系统需要利用现场总线。基于NetLinx现场总线的发电厂电气控制系统,不仅具有故障分析、信息管理、设备管理、自动抄表、仿真培训等高等级运行管理功能,而且具有结构灵活简单、可靠性高、适应性好、易于维护等优点。
Fieldbus is a serial, all dispersed, all digitized, intelligent, 2-way, muhivariable, multi-point, and multi-station communication system used between field instruments and control system or control room. As unit capacity increases and equipment become more and more decentralized, digitized, networked, and smart, fieldbus is needed by power plant electric control system. The Net Linx fieldbus-based power plant electric control system not only has many advanced operation management functions including failure analysis, information management, equipment management, automatic metering, and simulated training, etc., but also has many advantages such as simple and flexible structure, high reliability, good adaptability, and easy to maintenance, etc.
