Abstract: power management, that is, energy utilization, planning of electrical material consumption, organization, scheduling, control and some other column activities of a generic term, that is, the use of administrative, technical, economic means, using a set of power management system, the electricity The whole process of supply and use is to carry out systematic management activities. Electricity management is generally composed of four basic links for supply, use, control and supervision. Continuous innovation during operation can promote the continuous improvement of power management, and achieve university power through the Acrel-3000 power management system. The automatic management of consumption and the functions realized by the Acrel-3000 power management system provide statistical data for university energy and provide a basis for energy conservation .

In order to make students have a good learning environment, the school has made great efforts in teaching facilities and apartment conditions on campus. However, due to the open management model of university campuses, many university energy-saving measures only focus on behavior management and energy conservation publicity and education. The lack of application of humanized new technologies has been lacking. Coupled with the low awareness of energy conservation of many students, the phenomenon of waste has become more serious. With the continuous expansion of colleges and universities, the campus area, the number of students, the number of teaching staff has increased dramatically, and the public expenditures of various universities have been greatly improved compared to the past. Its main performance is the waste of electrical energy. In view of the above problems and the status quo, this topic proposes to develop a set of centralized monitoring systems for high and low voltage power distribution in colleges and universities using ACCOR's network power management instruments and Acrel-3000 configuration software . 1 Project Overview Heilongjiang Soybean R&D Center Energy Management System is a distribution system for the newly-built campus of Northeast Agricultural University . The monitoring scope of this project is the total incoming line of the low-voltage power distribution room and the instruments of each floor, including 503 intelligent metric instruments . The system mainly emphasizes the monitoring and control of real-time data. It mainly focuses on the entire process of intelligent monitoring of the reliability of the entire distribution system, data analysis, and statistics on the power used by each circuit. 2 user needs     According to the actual situation at the scene, the new power distribution center of the transformer substation puts forward the following system requirements:     1. Field instruments must realize real-time display functions: voltage, current, and energy monitoring information are refreshed in real time and visually and dynamically displayed in a single graph.     2. The on-site data report needs to meet the requirements for automatically generating daily, weekly, and monthly reports, and has export printing functions. 3. Alarms can be provided on the communication status or abnormal power consumption of each monitoring point so that the management personnel can grasp and analyze the distribution operation situation in real time. 3 design plan According to the on-site requirements, Ankerui Electric Co., Ltd. designed Acrel-3000 power management software for Heilongjiang Soybean Dairy Research and Development Center . The following describes the parameters of Acrel-3000 power management software. 3.1 Acrel-3000 Compliance Standards Soy dairy R & D center in Heilongjiang Province, the power management system to the current national standard and effective power industry as the basis, which are not included in section GB should refer to the latest IEC standards and norms. If there are contradictions between the standards, the higher standards shall prevail. The design of the system meets the following manufacturing and test standards: JGJ/T 16-92 Civil Building Electrical Design Code GB/J63-90     "Design Specification for Electrical Measuring Instrument Devices of Electrical Installations"  DL/T698-1999          "Technical conditions of centralized meter reading system for low-voltage power users"  DL/T645-1997          "Multifunctional Energy Meter Communication Protocol" GB2887 "Technical Requirements for Computing Station Sites" GB/50198-94 "Monitoring System Engineering Technical Specifications" 3.2 Network Structure Topology There are a total of 182 ACR network power meters and PZ three-phase energy meters in the second floor of the power distribution room , and a total of 321 ADL100 and ADL300 meters on the eight floors of the ground . A total of 32 shielded twisted pairs are used to connect to 16 ports. The serial port server and the serial port server collect data centrally through the switch , and the on-site meter to serial port server network is shown in Fig. 1 and Fig. 2 : figure 1 Figure 2 4 system function According to the site's requirements for the system, Ankerui Electric Co., Ltd. designed the project system interface and functions, the specific display interface is as follows: 4.1 System main interface Distribution Interface schematically: FIG intuitive in a form of a dynamic voltage, current, power and frequency monitoring information shown in Figure 3: Figure 3 4.2 Report Statistics Figure 4 4. 3 Communication status Figure 5 5 operation effect     The Acrel-3000 power management system solves the problem that the monitoring is not in place. For the campus power equipment, it performs all-around, all-weather, real-time, 24-hour real-time on the target area. Any equipment that does not meet the normal operation is audible and visually alarmed. This energy-saving monitoring system includes three parts: energy-saving, intelligent monitoring and burglar alarm. This system, together with the power-saving device, can realize the active power, reactive power, current, voltage and other working status data of the power equipment under the control of the power-saving device, and transmit data through an automatic wireless transmission system. Make energy-saving intelligent, automated and standardized . 6 Conclusion The energy-saving work on the university campus is a long-term work and a complicated task. There are many problems that we should seriously study, discuss, and reform. Smooth and effective to carry out energy-saving work, you need to take the initiative to schools with electricity management department closely with school-related departments, make concerted efforts to guide students to actively participate and create a good atmosphere for energy conservation, the scientific outlook on development of energy-saving work, do further Good energy-saving work, improve the energy-saving awareness of all teachers and students, do everything possible to save resources, make greater contributions to the sustainable development of the country and universities.
