The construction of a centralized and unified energy management system at the whole plant level can realize the online collection, calculation, analysis and processing of energy data, thus playing an important role in energy material balance, scheduling and optimization, and energy equipment operation and management.

01 项目概述及建设目标

浙江某铝塑业有限公司成立于2005年1月1日，是法国ILEOS下属的AXILONE公司与浙江上虞市某真空涂装有限公司合资成立的中法合资公司，由法国某公司控股。

Founded on January 1, 2005, Zhejiang Aluminum Plastic Co., Ltd. is a Sino-French joint venture company jointly established by AXILONE, a subsidiary of ILEOS, France, and a vacuum coating co., LTD. in Shangyu City, Zhejiang Province, and is controlled by a French company.

由于企业生产规模扩大，某铝塑业有限公司在杭州湾上虞工业园区新建厂区，整个新建厂区包括两个厂房、一栋宿舍楼，主要消耗能源包括电、水、压缩空气、蒸汽等。为了更好地掌握企业能源消耗、能源成本，某铝塑业在新厂区设计一套企业能源管理系统，并与原老厂区能源管理系统一起，作为企业内部考核管理的工具，并此基础上逐步整理完善企业能源管理数据库，对数据进行多层次全方面的开发利用（如决策需要、电能分析、数据报送）。同时通过网络技术使之成为作为浙江某铝业信息化系统的重要子系统，以实现智慧厂区和数字厂区。

Due to the expansion of the production scale of the enterprise, an aluminum plastic industry co., LTD. built a new factory in the Shangyu Industrial Park in Hangzhou Bay, and the entire new factory area includes two factories and a dormitory building, and the main energy consumption includes electricity, water, compressed air, steam, etc. In order to better grasp the energy consumption and energy costs of enterprises, an aluminum plastic industry designed a set of enterprise energy management system in the new factory area, and together with the original old factory energy management system, as a tool for internal assessment and management of enterprises, and on this basis, gradually sorted out and improved the enterprise energy management database, and carried out multi-level and all-round development and utilization of data (such as decision-making needs, power analysis, data submission). At the same time, through network technology, it has become an important subsystem of an aluminum industry information system in Zhejiang to achieve smart factory area and digital factory area.

02 能源管理系统的设计

在管理系统的设计中，充分考虑了企业自身特性，以及能源构成系统的实际结构、电力系统的实际载荷能力等因素，进而合理的选择管理设备，这既有利于减少系统运作的成本，同时也有利于系统功能的实现。

Real-time monitoring of the backhaul data of the field instrument, reasonable control and early warning of electric energy, timely discovery and correction of electrical abnormalities in operation, and processing at any time. Set the early warning value of important equipment exceeding the standard as needed, and give a prominent reminder and actively record when it exceeds the standard.

用电管理及计量体系的搭建

为了实现对用能回路的监管，系统设计了能源管理报表，系统通过对有功电度、用水、用气等能源的采集，按照回路名称的不同。按照计量体系搭建原则，自动生成日报表、月报表和年报表，将各进线回路与出线回路电能消耗量在同一张报表中体现出来，并计算出线回路用电量之和，出线回路与进线回路误差、误差百分比（误差百分比是否超标）等，帮助用户及时发现这种非正常用电问题。

In order to realize the supervision of energy-using circuits, the system designed an energy management report, and the system collected energy sources such as active electricity, water, and gas, according to the name of the circuit. According to the principle of metering system construction, the daily report, monthly report and annual report are automatically generated, and the power consumption of each inlet circuit and the outlet circuit is reflected in the same report, and the sum of the electricity consumption of the line loop is calculated, the error between the outlet loop and the inlet loop, the error percentage (whether the error percentage exceeds the standard), etc., to help users find this abnormal electricity problem in time.

同时电能管理系统可对某一回路的某一时间段内的用电量进行查询，可以帮助后勤管理部门建立用能管理考核制度。通过系统的建设和制度的建立，使各部门办公、生产人员节能意识大大提高，节约了企业管理办公能源消耗。

At the same time, the electric energy management system can inquire about the electricity consumption in a certain period of time in a certain circuit, which can help the logistics management department establish an energy consumption management assessment system. Through the construction of the system and the establishment of the system, the energy-saving awareness of the office and production personnel of various departments has been greatly improved, and the energy consumption of the enterprise management office has been saved.

能源流向图

能源流向图表示的是能源介质流向的一种示意图，直观形象地概括了企业能源系统的全貌，反应了企业在能源输入及分配输送方面的平衡关系。

The energy flow chart represents a schematic diagram of the flow direction of the energy medium, which intuitively summarizes the overall situation of the enterprise's energy system and reflects the balanced relationship between the enterprise in terms of energy input and distribution and transmission.

电能质量

某新厂房生产线有很多新仪器，对电能质量要求较高，特别是电磁波，同时由于谐波的产生会造成变压器、输电线路等电气设备附加损耗与发热，缩短使用寿命，造成设备震动和噪声；谐波谐振过电压，造成电气元件及设备的故障与损坏；引起电能计量错误；重要的自动控制、保护装置不正确动作；IT芯片制造成品率降低等等，通过电能质量的监测，能随时掌握每条生产线路电能质量，并及时给出治理方案，确保电能质量。

A new plant production line has a lot of new instruments, the power quality requirements are high, especially harmonics, and because of the generation of harmonics will cause transformers, transmission lines and other electrical equipment additional loss and heat, shorten the service life, resulting in equipment vibration and noise; harmonic overvoltage, resulting in electrical components and equipment failure and damage; causing power measurement errors; important automatic control, protection device incorrect action; IT chip manufacturing yield reduction, etc., through the monitoring of power quality, Can grasp the power quality of each production line at any time, and timely give the treatment plan to ensure the power quality.

数据共享

某新老厂区均配置能源管理系统，为了方便企业管理人员对新老厂区能源系统统一管理，整个新建厂区能源管理系统可以通过企业内部专网，实现新老厂区数据共享，方便业务能源管理能源统一管理，提高效率。

A new and old plant area are equipped with energy management system, in order to facilitate the enterprise management of the new and old plant energy system to agree to manage, the entire new plant energy management system can be through the enterprise internal private network, to achieve the new and old plant data sharing, convenient business energy management energy unified management, improve efficiency.

03 企业能源管理系统的意义

综上所述，能源管理系统帮助用能单位提高效率、减少损失、降低运营成本，能源管理系统能够确保电网管理效率、缩小运营成本，也成为供配电设计中不可或缺的重要组成部分。能源管理系统的通信、故障报警、数据存储记录等功能使得工作人员在实际工作中更加方便，可以通过人机操作界面, 直接了解到智能设备的运行状态,并能迅速传递出操作指令，由于监控设备对数据的传递都是通过网络传输来实现，因此，不同的能源管理系统可以设计不同的组网方式,确保数据信息能够迅速进行传输。另一方面，在企业能源管理设计中运用能源管理系统，应该根据实际情况选择计量装置。

In summary, the energy management system helps the energy user unit to improve efficiency, reduce losses, reduce operating costs, energy management system can ensure the efficiency of grid management, reduce operating costs, and become an indispensable part of the power supply and distribution design. Energy management system communication, fault alarm, data storage records and other functions make the staff in the actual work more convenient, through the man-machine operation interface, directly understand the operating status of the energy equipment, and can quickly transmit the operation instructions, because the monitoring equipment on the transmission of data are through the network transmission to achieve, therefore, different energy management systems can design different networking methods, to ensure that data information can be quickly transmitted. On the other hand, the use of energy management systems in the design of enterprise energy management should be based on the actual situation of the metering device.

在工业企业设置能源管理系统，可以实现对企业内能源计量分产线、分厂区、分产量等进行统计分析，不仅能够准确的表示出回路的用能状况，它还具备网络通讯等功能，能够与计算机、串口服务器等设备进行组合，及时的显示楼内各条生产线的运作状态，当某设备电力系统的负载越标时，能源管理系统能够迅速报警，发出语音提示。另外，能源管理系统还能够生成报表、曲线图等统计信息，便于有关人员分析企业各部门的用能状况，使企业的用能活动更加安全，从而保证企业生产人员的生命安全，提高生产人员的工作效率。

In the industrial enterprises to set up energy management system, can achieve statistical analysis of the energy metering sub-production line, sub-plant area, sub-output, etc. in the enterprise, not only can accurately represent the energy consumption status of the circuit, it also has network communication and other functions, can be combined with computers, serial port servers and other equipment, timely display the operation status of each production line in the building, when the load of a certain equipment power system exceeds the standard, the energy management system can quickly alarm, send out voice prompts. In addition, the energy management system can also generate statistical information such as reports and curve charts, which is convenient for relevant personnel to analyze the energy consumption status of each part of the enterprise, so that the energy consumption activities of the enterprise are more secure, so as to ensure the life safety of the production personnel of the enterprise and improve the work efficiency of the production personnel.
