0 Preface
As the hotspot of domestic industrial reform at the international level, industrial intelligence is optimized and upgraded for process technology in industrial manufacturing to improve efficiency and reduce energy consumption. As an important part of the industrial intelligentization process, the current industrial energy management is mainly for the energy consumption monitoring of equipment in industrial production, through the long-term data collection and analysis, targeted and energy-saving retrofit solutions, and industrial manufacturing process optimization. , thereby increasing production efficiency and reducing unit energy consumption.
The Acrel-5000 energy management system is an enterprise user energy management system developed for the above trends. The system measures the important equipment circuit in the factory of Nantai Home Textiles Factory. Through the real-time measurement, storage and analysis of the electricity consumption of the monitoring circuit, the power consumption status of the entire measurement system is displayed in the form of a table or a graph to find out the high energy. Consumption point or irrational use of energy habits, in order to effectively save energy, users provide accurate data support for further energy-saving transformation or equipment upgrade.
This article takes Nantai Home Textile as an example to briefly introduce the application of the Acrel-5000 energy management system in the civil aviation power distribution system.
1 Project introduction
Jiangyin Nantai Home Textiles Co., Ltd. was established in January 2005. The company has a plant area of ​​over 50,000 square meters and employs more than 1,600 people. In 2013, its sales revenue exceeded RMB 1.3 billion. The company's products are mainly sofa covers, mattress covers, curtains, cushions and bedding. More than 95% of them are exported to European and American markets. One of the main customers is IKEA, the world's largest home furnishing company. The company has more than 370 companies in IKEA Greater China. The top among suppliers.
Nantai Home Textiles is also subject to the limitations of existing hardware and software while adopting various methods for energy management and transformation. Due to the manual reading of most energy consumption processes and monitoring of key energy-consuming equipment, there is a lack of data collection and analysis of intelligent instrumentation records and automation systems. The data of manual reading is long and the timeliness is poor. The statistical method is single. At the same time, it cannot be combined with the automation of production technicians. There are still major deficiencies in the advanced management of energy consumption.
The project focuses on solving the intelligent, automated, visual, and quantifiable collection and storage of basic energy consumption data; establishing an energy management platform for enterprises and realizing centralized management of various energy sources; focusing on optimizing power consumption and reducing electricity expenses; In-depth analysis of energy consumption processes and trends, and achieve a close integration of energy management and production technology.

5 Conclusion
Industrial automation, informatization is an inevitable trend of industrial development. At present, most industrial production areas still remain in the state of manual meter reading and extensive management with unclear details. For Nantai Home Textiles, through the construction of the Acrel-5000 energy management system, the main energy consumption of the three factories in the Nantai Home Textiles Factory will be refined and stored, analyzed and managed in real time. Through the specific data to show the energy consumption trend of the ex-factory area and the habit of using energy, it provides a solid and reliable scientific basis for the manager to optimize the production process and optimize management in the later stage.
In the Nantai home textile project, the energy consumption measurement system is built for the energy consumption of the plant. In the later stage, the water, gas and other energy of the plant can be incorporated into the system, so that the energy consumption data of the system is more comprehensive. Then, by incorporating the production capacity, the unit consumption is calculated, the unit consumption of each shift group is compared, and a reasonable assessment plan is established to improve the energy utilization rate and reduce the cost.
