With the reform of higher education management system and adjustment of layout and structure, higher education resources have expanded and the scale of universities has been expanding. As the school's teaching buildings, libraries, laboratories and student dormitories are newly built or renovated, the power consumption capacity and power distribution facilities need to be further upgraded. Intelligence has increasingly penetrated into every corner of our lives, and the power distribution system is also making unremitting efforts to achieve its own intelligence.

There are relatively few primary loads among the electrical loads in colleges and universities. Only some high-precision instruments in laboratories require continuous power supply. The loads in other buildings are mostly secondary and tertiary loads. Among them, air-conditioning system equipment in teaching buildings, student dormitories and other places where electricity is concentrated require focused management of electricity use; fire-fighting electricity needs to be equipped with EPS power supplies.

There is a problem:

1. The scale of universities is expanding day by day, and the requirements for the transformation and upgrading of power distribution systems are increasing.

2. Colleges and universities have achieved a qualitative leap in terms of both software facilities and hardware equipment, so their requirements for intelligent power distribution systems are getting higher and higher. 

3. Low degree of automation: When the power supply is tight, the means of load control and electric energy distribution are backward, and remote control of load distribution and transfer cannot be achieved.

4. The loads of universities can also be divided into three levels, and different power supply measures are adopted for different levels of electrical loads. The types of university buildings are divided into teaching, experiments, apartments, residences, canteens, etc. Therefore, different buildings are equipped with corresponding instruments for power distribution monitoring.

Shift towards intelligence.

School power distribution automation solution:

The basic requirements for the power distribution plan of colleges and universities are as follows: Integration of monitoring, and in case of emergency, the management staff will be notified and responded to immediately.

Control requirements:

1. When any one of the two high-voltage circuits loses power, the circuit breaker operates, the bus coupler is closed, and a start command is issued to the diesel generator. When both high-voltage circuits lose power, the diesel generator is immediately put into power supply;

2. When a transformer or a circuit fails, it will be cut off non-guaranteedly to protect the primary load and important secondary load;

3. Fire protection priority;

4. UPS power supply emergency preparation, for laboratory key experimental equipment, computer equipment, fire protection equipment, elevators and other equipment.

Basic configuration of power distribution rooms in university buildings:

1. Configure the number of transformers, the number of high-voltage cabinets and low-voltage cabinets according to the design capacity of the hospital. Use power meters to monitor the incoming and outgoing circuits of all low-voltage cabinets, and upload the data to the intelligent power distribution system. Depending on the scale and requirements of the university, the requirements for the intelligent power distribution system will be different, but in essence, all terminal data are collected through multi-functional power meters and uploaded to the host computer system through the communication bus. Software processing enables monitoring and control of smart buildings.

2. The intelligent power supply and distribution system can be divided into three layers from a structural point of view: on-site I/O, communication management layer and central control layer. Among them, the control layer is the control core of the entire system, monitoring and controlling the operation of the power supply system, and can also be used for human-machine dialogue interface, data processing and storage management; on-site I/O is used for on-site equipment status signals and operating parameters. collection, and control operations on field equipment.

The power distribution room is usually equipped with two transformers, uninterruptible power supply EPS, UPS, DC panel and several high and low voltage distribution cabinets. Usually, power meters are configured on the power distribution cabinet for terminal data collection.
