【摘要】：火电厂既是一次能源的消费大户，又是节能减排的重点生产企业，对实现国家节能减排目标具有举足轻重的作用。从我国能源供需矛盾、火电厂主要能耗指标与世界先进水平的差距及发电设备设计制造技术水平等方面看火电厂存在巨大节能降耗潜力，随着信息技术的发展，能源管理系统在火电厂节能方面的作用日益重要，在国内外现有EMS研究基础上积极充分发挥其作用是可实现的。在论述能源管理系统（EMS）分析、设计、项目管理相关基本理论基础上，本文主要结合电厂的实际情况，从火电厂电力生产过程入手，包括燃烧系统、汽水系统、电气系统等，进行了能源管理系统分析，包括需求分析和能源管理内容分析两部分，构建了业务流程图、数据流程图。在信息技术的基础上对电厂能源管理系统进行了模块设计，在设计中论述了设计方法、模块内容与功能、系统逻辑架构、代码设计、数据库设计等内容，数据库设计包括表结构设计、基本E-R图、物理设计等，模块设计包括能源计划、能源监控、能源统计、能源计量、能源计算与分析、重点能耗设备管理等，，最后根据分析过程和系统的设计构建能源管理系统架构图。介绍了数据库的概念、原则、方法，数据库设计有三个阶段，最为关键的是第一阶段，即构建E-R图，表的设计，最后进行了代码设计、输入输出设计等。通过对水电等能源的信息采集、统计、分析、报表等各个阶段，发现能源管理中存在的问题，针对不同能源类别给出合理建议，达到节能降耗的目的。
[Abstract]:Thermal power plant is not only a big consumer of energy consumption, but also a key production enterprise of energy saving and emission reduction. It plays an important role in realizing national energy saving and emission reduction target. From the contradiction of energy supply and demand in China, the gap between the main energy consumption index of thermal power plant and the world advanced level and the technology level of the power generation equipment in the manufacturing technology, the thermal power plant is huge. With the development of information technology, energy management system plays an increasingly important role in energy conservation in thermal power plants. It is possible to fully play its role on the basis of existing EMS research at home and abroad.
On the basis of the basic theory of the energy management system (EMS) analysis, design and project management, this paper, based on the actual situation of the power plant, starts with the power production process of the power plant, including the combustion system, the steam water system, the electrical system and so on, and carries out the analysis of the energy management system, including the two parts of the demand analysis and the analysis of the content of energy management. A business flow chart and a data flow chart are built.
On the basis of information technology, the power plant energy management system is designed. In the design, the design method, the module content and function, the system logic architecture, the code design, the database design and so on are discussed. The database design includes the table structure design, the basic E-R diagram, the physical design and so on. The module design includes energy planning, energy monitoring, and so on. Energy statistics, energy measurement, energy calculation and analysis, key energy consumption equipment management and so on. Finally, based on the analysis process and the design of the system, the energy management system architecture diagram is constructed. The concept, principles and methods of the database are introduced, and the database design has three stages, the most critical is the first stage, that is, the construction of the E-R diagram, the design of the table, and the final conduct. The design of code, the design of input and output, and so on. Through the information collection, statistics, analysis, report and other stages of energy resources of hydropower, the problems in energy management are found, and the reasonable suggestions are given for different energy categories to achieve the purpose of saving energy and reducing consumption.
