基于B/S模式的600MW火电机组回热系统
在线监测系统研究
摘要
 能源是社会发展的重要物质基础。就人均资源占有量而言，我国是一个人均资源占有量贫乏的国家，并且我国的能源利用率大大低于发达国家水平，单位国民生产总值能耗是发达国家的3～5倍，对能源问题我国政府历来十分重视，节能是我国能源战略和政策的核心，为了加强能源管理，合理开发和有效利用能源，我国政府提出了实行“节能优先、结构多元、环境友好、市场推动”的可持续能源发展战略。
 电力企业作为耗能大户，是节能减排的重点单位。随着我国电力工业的发展，600MW火电机组已经成为现在的主力机组，提高其经济性无疑具有很大的现实价值。回热系统作为发电厂热力系统的重要组成部分之一，对发电厂安全经济运行的影响很大。如果回热系统故障，则发电煤耗将增加，且机组的出力将降低，所以对回热系统进行热经济性研究有很大的经济价值。本文分析了600MW火电机组的回热系统的结构，在研究了电厂热经济性分析方法的基础上，研究了基于600MW火电机组回热系统分析模型，并将其应用到在线监测系统之中。此外，本文叙述了从C/S模式到B/S模式的发展，对基于B/S模式的600MW火电机组回热系统在线监测系统进行了阐述。

Based on B/S 600 MW coal-fired power units to regenerate system on-line monitoring system
Abstract
 Energy source provided the foundation for the development of society. Our country is poor in energy resources counted by a person’s appropriation, and the usage ratio of energy source in our country is far lower than advanced country, the energy sources cost of GDP is 2～4 times than advanced country. Our country always attaches importance to energy source matter, and saving energy is the kernel of our country’s energy policy.
 Power business as a major energy-consuming, energy-saving is the focus of emission reduction units. As China''s power industry development, 600 MW coal-fired power units have now become the main force units, enhance its economy is undoubtedly of great practical value. Regenerate system as an important component of thermal power plants, the system of safe and economic operation of power plants in the great impact. If the regenerate system failure, the coal consumption for power generation will increase, and the unit will contribute to lower, so the regenerate system of economic studies has great economic value. This paper analyses the structure of the 600 MW coal-fired power units of the regenerate system, thermal power plants in the study of the economic analysis on the basis of a study based on 600 MW coal-fired power units back to thermal analysis model, and apply it to on-line monitoring system. In addition, this paper, from the C/S model to the B/S model of development, based on B/S 600 MW thermal power units to regenerate system on-line monitoring system were also discussed.
