【摘要】：钢铁行业是一种高耗能产业,因此在钢厂实施节能技术潜力巨大。过去对于热轧过程耗电量的测算只能采取手算加估算方式,凭粗略的计算及经验估算得出电耗。跟实际值差多少,谁也估不准,也就很难为钢厂进行系统性的能耗分析提供详尽、准确、科学的决策数据。本研究具有广泛的应用价值,如成功开发出此套计算平台,可推广到各大钢铁企业,通过该计量平台获得的数据进行节能降耗项目就会有的放矢,为国家节约大量资金,具有极大的市场应用前景及社会意义。本文基于宝钢1780mm热轧厂的实际生产情况,针对热乳生产过程中的电能消耗,设计了一套合理的动态电能采集及管理系统(Electric Energy Acquisition and analyzing Systems,EAAS),该系统能统计和分析热乳过程的各流程的电能消耗,并进行了统计分析。电能数据采集与分析系统已广泛应用于各个领域,但当前的电能数据采集是静态的,如对一天或一个月的电能定时进行计量与统计。本文提出的电能采集系统,利用SEL保护装置的测量功能,将实时采样值进行后台处理,计算得出一段时间的能耗,同时,通过与L2系统的通信准确获得不同钢种在不同工段的起止时间,通过采样值积分获得准确的工段电耗。在系统设计上采用三层网络结构,SEL装置为间隔层,ROC6000通信管理机及通信网络构成网络层,站控层保护数据服务器及工作站。在系统软件方面,通过积分算法实现了不同工段的能耗计算,给出了粗轧、精乳和卷取等各个环节不同的电能消耗量,并绘制了实时功率曲线。利用通信管理机实现了 DNP通信规约以及和L2系统的通信规约,实现了系统数据采集和数据交互。经过长期测试,系统的各个功能均完成生产工艺需求,且系统运行正常、稳定。
[Abstract]:Iron and steel industry is a kind of high energy-consuming industry, so it has great potential to implement energy-saving technology in steel plant. In the past, the calculation of power consumption in hot rolling process can only be done by manual calculation and estimation, and the electricity consumption can be estimated by rough calculation and experience. It is difficult to provide detailed, accurate and scientific decision data for systematic energy consumption analysis of steel mills. This research has the extensive application value, if successfully develops this set of calculation platform, may popularize to each big iron and steel enterprise, through this metering platform obtains the data to carry on the energy saving and the consumption reduction project will have the target, saves a large amount of money for the country. It has great market application prospect and social significance. Based on the actual production situation of Baosteel 1780mm hot rolling mill, this paper aims at the electric energy consumption in the process of hot milk production. A set of reasonable dynamic power acquisition and management system (Electric Energy Acquisition and analyzing Systems,EAAS) is designed. The system can calculate and analyze the power consumption of each process in the process of hot emulsion and make statistical analysis. Power data acquisition and analysis system has been widely used in various fields, but the current power data acquisition is static, such as a day or a month of energy timing measurement and statistics. The power acquisition system proposed in this paper uses the measurement function of the SEL protection device to process the real time sampling value in the background, and calculates the energy consumption for a period of time, at the same time, Through the communication with L2 system, the starting and ending time of different steel grades in different working sections are obtained accurately, and the accurate power consumption of different working sections is obtained by integrating the sampling values. In the system design, the three-layer network structure and SEL device are used for the interval layer ROC6000 communication management machine and communication network to form the network layer, the station control layer protects the data server and the workstation. In the aspect of system software, the energy consumption of different sections is calculated by integral algorithm, and the different energy consumption of rough rolling, finishing milk and coiling are given, and the real time power curve is drawn. The DNP communication protocol and the communication protocol with L2 system are implemented by using the communication manager, and the system data collection and data interaction are realized. After long-term test, all functions of the system complete the production process requirements, and the system runs normally and stably.
