电气监控管理系统(ECMS),是为提高发电厂电气系统的自动化及运行管理水平,应用计算机、测量保护与控制、现场总线技术及通信技术,实现发电厂电气系统的电气运行、保护、控制、故障信息管理及故障诊断、电气性能优化等功能而提出的综合自动化在线监控管理系统。本篇论文是基于工业以太网和现场总线的火电厂电气自动化系统,描述了系统的网络结构以及ECS系统与DCS的接口方式。
首先介绍发电厂电气系统的现状,分析电气纳入DCS所存在的不足,提出改进措施,即用建立厂用电气监控管理系统实现电气联网接入DCS,并与DCS之间保持一定的独立性,二者之间通过以太网或者现场总线联系的方法解决。根据电厂电气系统的特点以及系统功能需求,设计建立电气监控管理系统的硬件结构,在此基础上架设软件系统,并重点就系统的软件体系结构和具体设计进行重点阐述。最后通过实际应用结果证实该系统的可行性,合理性。

第二章 Abstract
Electric Monitoring Management System (ECMS), is to improve the plant's automation and electrical systems operation and management level, computer applications, and measurement and control, field bus technology and communication technology, electrical power plant electrical system operation, protection, control, fault information management and troubleshooting, electrical performance optimization features such as integrated automation line proposed monitoring and management system. This paper is based on Industrial Ethernet and fieldbus Power Plant Electric Automation System, describes the network architecture and interface mode ECS and DCS systems.
Introduces the status quo power plant electrical system, electrical analysis included lack of DCS is present, suggest improvements, namely the establishment of plants with electrical monitoring and management system to achieve electrical interconnection access DCS, and maintain a certain degree of independence between the DCS and, two among those addressed by Ethernet or fieldbus contact method. According to the characteristics of the plant electrical system and the system functional requirements, design build hardware structure of electrical monitoring and management system, set up software system on this basis, and emphasis on software architecture and detailed design of the system focuses on the system for. Finally confirmed the feasibility of the system, through the practical application of the reasonableness of the results.
