Design of power management system for Heilongjiang soybean dairy R & D center of Northeast Agricultural University Abstract: power consumption management is the general term for the planning, organization, scheduling, control and other activities of power utilization and electrical material consumption, that is, the use of administrative, technical and economic means, the use of a complete set of power management system to systematically manage the whole process of power supply and use. Power consumption management is generally composed of four basic links: supply, use, control and supervision. Continuous innovation in operation can promote the continuous improvement of the work level of power consumption management. The automatic management of university power consumption and the functions realized by the acrel-3000 power management system can be realized through the acrel-3000 power management system, which provides university power statistics and decision-making basis for energy conservation

0 introduction

with the rapid development of the national economy and social progress, higher education has received the attention and attention of the whole society, and the scale of running schools has also been expanding with the increase of the number of educated people. In order to provide students with a good learning environment, the university has made great efforts in the teaching facilities and apartment conditions on the campus. However, due to the open management mode of the university campus, many energy-saving measures in Colleges and universities only focus on behavior management and energy-saving publicity and education, and lack in strengthening the application of humanized new technologies. In addition, many students have a weak awareness of energy conservation, resulting in serious waste. With the continuous expansion of the scale of colleges and universities, the campus area, the number of students and the number of teaching staff have increased sharply, and the public expenditure of colleges and universities has increased significantly compared with the past. It is mainly manifested in the waste of electric energy

in view of the above problems and current situation, this topic proposes to develop a set of centralized monitoring system for high and low voltage power distribution in Colleges and universities by using the network energy management instrument of ankerui company and acrel-3000 configuration software

1 project overview

the electric energy management system of Heilongjiang soybean dairy R & D center is a power distribution system in the new campus of Northeast Agricultural University. The monitoring scope of the project includes the main incoming line of the low-voltage distribution room and the instruments on each floor, including 503 intelligent instruments of ankerui. This system mainly emphasizes the monitoring and control of real-time data, and mainly carries out the whole process intelligent monitoring and data analysis for the reliability of the entire distribution system, And make statistics on the electric energy used by each circuit

2 user requirements

according to the actual situation on site, the power distribution management department of the new core substation puts forward the following system requirements:

1. The field instruments must realize the real-time display function: the voltage, current and electric energy monitoring information must be refreshed in real time, and visually and dynamically displayed in the form of a graph

2. The field data report shall be able to automatically generate daily, weekly and monthly reports, and have the function of export and printing

3. It can alarm the communication status or abnormal power consumption of each monitoring point, so that the management personnel can grasp and analyze the power distribution operation in real time

3 design scheme

according to the site requirements, ankerui Electric Co., Ltd. has designed acrel-3000 power management software for Heilongjiang soybean dairy R & D center. The following is a specific description of the parameters of acrel-3000 power management software

3.1acrel-3000 meets the standard

the power management system of Heilongjiang soybean dairy R & D center is based on the current effective national and power industry standards, and the parts not listed in the national standards should refer to the latest IEC standards and specifications. In case of any contradiction between standards, the higher standard shall prevail

the design of the system meets the following manufacturing and test standards:

jgj/t code for electrical design of civil buildings

gb/j code for design of electrical measuring instruments of power installations

dl/t technical conditions for centralized meter reading system for low voltage power users

dl/t communication protocol for multi-functional watt hour meters

gb2887 technical requirements for computing station site

gb/engineering technical code for monitoring system

3.2 topology diagram of network structure

182 sets of ACR network power meters and PZ three-phase watt hour meters are used in the distribution room on the second floor underground. 321 pieces of adl100 and adl300 are used in the distribution box on the eighth floor above the ground. The users mainly consider the tonnage of the experimental machine and the structure and control mode of the experimental machine. A total of 32 shielded twisted pairs are used to connect to 2 sets of 16 port serial server. The serial server conducts centralized data collection through the switch, The group from the field instrument to the serial port server is shown in Figure 1 and figure 2:

4 system functions

according to the system requirements on site, ankerui Electric Co., Ltd. has designed the system interface and functions of the project. The specific display interface is as follows:

4.1 system main interface

power distribution schematic interface: visually and dynamically display the voltage, current The monitoring information such as power and frequency is shown in figure 3:

figure 3

4.2. The report statistics the active electricity data collected by the

system. The report is automatically generated according to the different circuit names and has the report printing function. It can query and print the power consumption of a certain circuit in a certain period of time. At the same time, these reports can also be exported in Excel format

4.3 communication status

the system monitors the communication status of all points on the site. Red and green respectively represent the normal and abnormal instrument communication, which is convenient for users to view the communication status of each monitoring point, as shown in figure 5:

figure 5

5 operation effect

acrel-3000 electric energy management system, which solves the problem of inadequate monitoring. For the electric equipment in the campus, it can carry out all-round All-weather 24-hour real-time, any equipment that does not conform to the normal operation will give an audible and visual alarm. The energy-saving monitoring system includes three parts: energy saving, intelligent monitoring and anti-theft alarm. This system, together with the power saving device, can realize the active power, reactive power, current, voltage and other working state data of the power equipment under the control of the power saving device, and transmit the data through the automatic wireless transmission system. Make energy conservation intelligent, automated and standardized

6 conclusion

power saving on university campuses is not only a long-term work, but also a complex work. There are many problems worthy of serious study, discussion and reform. The smooth and effective implementation of electricity conservation requires the school's electricity management department to actively cooperate with the relevant departments of the school, make joint efforts, guide the students to actively participate, form a good energy-saving atmosphere, guide the overall situation of energy conservation with a scientific concept of development, further do a good job in energy conservation, improve the energy-saving awareness of all teachers, students and staff, do everything possible to save resources, and make greater contributions to the sustainable development of the country and colleges and universities

Abstract: power consumption management is the general term for the planning, organization, scheduling, control and other activities of electric energy utilization and electrical material consumption, that is, to systematically manage the whole process of power supply and use by using administrative, technical and economic means and a complete set of power consumption management system. Power consumption management is generally composed of four basic links: supply, use, control and supervision.
