【摘要】：随着我国工业化和信息化步伐的加快,能源不可替代的地位显得越来越突出,而怎样高效的利用能源,达到人类与环境协调发展,则是我们当前的首要目标。目前,造纸企业能源管理粗放,排污量大,能源消耗大,信息化程度低,传统不科学的能源管理方式已经不适合造纸企业的发展,而利用网络技术和计算机技术对造纸企业能源进行管理显得尤为重要,同时在造纸企业建设能源管理系统(EMS)具有巨大的社会与经济效益。本文以山东某造纸企业为设计对象,该企业在造纸行业具有典型的代表性,通过对该造纸企业的实地考察和对网络技术和数据采集等技术的研究,设计出适合该造纸企业的能源管理系统。本文的具体工作如下：(1)能耗数据采集系统的设计。通过统计和分析该造纸企业能源计量点的数量、种类以及分布,完成蒸汽系统、电力系统和清水系统等能耗数据采集系统的设计,确保能耗数据准确、快速、稳定地上传至能源管理系统。(2)能源管理系统网络架构的设计。在网络技术的基础上,分析该造纸企业目前网络结构,统计该企业信息点(包括语音点和数据点)的数量和分布情况,遵循可靠性、安全性和实时性设计的原则,对能管系统网络重新设计,采用双环网双服务器的结构,确保数据交换安全可靠。同时,为了实现能源的统一分配和集中监控,设计能管监控中心,对企业进行无死角监控,确保安全高效生产。(3)基于改进BP神经网络的电量需求预测算法的实现与仿真。为了更好的进行能源购置及分配,以BP算法为基础,对电量需求预测算法展开研究,以该企业某个车间一个月的耗电量为基础,应用MATLAB软件进行建模仿真,并将改进BP网络与标准BP网络预测效果进行对比。(4)造纸企业能源管理系统硬件设计及软件开发。根据能管系统功能,以过程控制软件PCS7和能源管理软件B.Data为基础,完成能管系统控制层、操作层和管理层的软件设计,其中控制层软件包括控制层硬件组态、数据采集、滤波、流量累积、报警以及连锁等；操作层软件设计包括水、电、汽的过程画面以及各历史趋势等；管理层软件设计包括登录画面、WEB发布、能耗数据报表,最终完成能管系统的设计,实现该造纸企业的信息化管理。本课题根据实际需要,对造纸企业的能管系统进行了设计,为满足能源管理系统的要求,对能管系统网络架构进行设计,实现企业无死角实时监控,为了合理购置和分配电能,以BP算法为基础,对造纸企业电量需求及预测展开分析研究,最后完成了能管系统硬件设计及软件开发,使该企业能源管理达到一个新高度,实现节能减排。
[Abstract]:With the acceleration of industrialization and informatization in our country, the irreplaceable position of energy appears to be more and more prominent, and how to use energy efficiently to achieve the harmonious development of human and environment is our primary goal at present. The energy management of papermaking enterprises is extensive, the amount of sewage is large, the energy consumption is large, the information level is low, and the traditional unscientific energy management method is not suitable for the development of papermaking enterprises. It is very important to use network technology and computer technology to manage the energy of papermaking enterprise. At the same time, the construction of energy management system (EMSs) in papermaking enterprise has great social and economic benefits. In this paper, a papermaking enterprise in Shandong Province is taken as the design object. This enterprise has typical representation in paper industry, through the field inspection of the paper making enterprise and the research of network technology and data collection, etc. The energy management system suitable for the papermaking enterprise is designed. The specific work of this paper is as follows: 1) the design of the energy consumption data acquisition system. Through statistics and analysis of the number, type and distribution of the energy metering points in the papermaking enterprise, the steam system is completed. The design of energy consumption data acquisition system, such as power system and clean water system, ensures the accurate, fast and stable upload of energy consumption data to energy management system. This paper analyzes the present network structure of the papermaking enterprise, statistics the quantity and distribution of the enterprise information points (including voice points and data points), and redesigns the energy management system network according to the principles of reliability, security and real-time design. In order to realize the unified distribution of energy and centralized monitoring, the monitoring center of energy management is designed to monitor the enterprises without dead-angle in order to ensure the safety and reliability of data exchange by adopting the structure of dual-ring network and dual-server. To ensure safe and efficient production. (3) the realization and simulation of electricity demand forecasting algorithm based on improved BP neural network. In order to purchase and distribute energy better, based on BP algorithm, the electricity demand forecasting algorithm is studied. Based on the power consumption of a workshop in this enterprise for one month, the modeling and simulation are carried out by using MATLAB software. The paper compares the prediction effect of improved BP network with that of standard BP network. The hardware design and software development of energy management system in papermaking enterprise are compared. According to the function of energy management system, the process control software PCS7 and the energy management software B.Data are used as the basis. Complete the software design of the control layer, the operation layer and the management layer of the energy management system. The control layer software includes the hardware configuration of the control layer, data acquisition, filtering, flow accumulation, alarm and interlock, etc, and the software design of the operation layer includes water, electricity, electricity, etc. The design of management software includes login screen and Web release, energy consumption data report, finally complete the design of energy management system, realize the information management of the papermaking enterprise. The energy management system of papermaking enterprise is designed. In order to meet the requirements of energy management system, the network structure of energy management system is designed to realize real-time monitoring without dead angle. In order to reasonably purchase and distribute electric energy, BP algorithm is used as the basis. In this paper, the energy demand and forecast of paper making enterprise are analyzed and studied. Finally, the hardware design and software development of energy management system are completed, which makes the energy management of the enterprise reach a new level and realize energy saving and emission reduction.
