Optimize the energy consumption of  base-station, ensure safe operation and reliability/management of power distribution

Through the implementation of a powerful intelligent power terminal system(Intelligent recloser, intelligent air circuit breaker ammeter in Internet of Things), ensure safety for electricity use and risk-free operation of data center & communication base station, improve the stability of communication base station distribution system.

Project Background

Yuhua district near the west of Liuyang River downstream, with abundant rainfall, rain and heat over the same period, four distinct seasons, longitude: 113.63, latitude: 28.15; the landform is hilly and mountainous. The number of thunderstorm days in the region was 49.5, according to the classification of thunderstorm day can be divided into multiple minefields, thunderstorm season the power cuts out due to thunder. The base station is located in a mountainous area with humid air.

 

The base station is located in a half hillside, the engine room is under the tower, the transformer is down the hill. The low-voltage cable enters the machine room along the hillside, power supply is of three types. Power failure accidents caused by voltage fluctuation and power supply quality, which affect communication quality and require a large amount of operation and maintenance costs.

 

Now, the base station ac distribution box is equipped with multi-circuit ac metering intelligent ammeter device and circuit breaker, to measure ac input and output sub-circuits, and to protect circuit from short-circuit and overload. 

 

As the measurement data of traditional electricity meters are not uploaded, the power consumption of base stations cannot be known timely;traditional circuit breakers must be manually reset after the circuit breaks down; the reason of  trip-out was’t clear; and the circuit breaker is difficult to achieve upper and lower selective protection; fault current was bigger, which was  easy to cause the instantaneous disconnection of the upper and lower level circuit breakers

Customer requirement

A new set of municipal incoming power management system, which comprehensively utilize mobile internet, communication, artificial intelligence technology, man-machine interactive technology, can realize the functions of power line management, intelligent analysis, electricity safety and electricity data monitoring,to realize the effective monitoring and management of base station electricity consumption, ensure the reliability of equipment operation, safety of electricity consumption, effect of energy saving, and meet the requirements of operation and maintenance.

Scope of supply

>MT61GPS-63-G2、MT61GPT-63-G2Intelligent air circuit breaker ammeter in Internet of Things
>MT51RS-2P-63、MT51RS-4P-63Intelligent recloser
>M5EL-4P-125、M5EL-4P-250Intelligent molded case meters with Internet of Things
>MT-88Communication gateway

Result

Changsha Hongxian mountain base station-The municipal power management and electricity supervision system has returned to normal operation, and finish the final acceptance work.

Scheme

Intelligent power consumption supervision and power management platform, combine with perfect power distribution system and supervisory control system, using mobile internet, communication, artificial intelligence technology, man-machine interactive technology, which can realize the functions of power line management, intelligent analysis, electricity safety and electricity data (meter, running) monitoring.    

The system can automatically quickly identify and alarm the abnormal electricity consumption, which improve the operation and management efficiency of distribution and electricity system and facilities, and reduce operation cost. Meanwhile,the system realizes automatic timing management, electricity data detection and statistics, which can timely obtain the energy consumption data of the equipment and ensure the data systematization. Comprehensive data report and trend analysis, perfect power consumption data and management means for base station, achieved the goal of reducing operation energy consumption and automatic operation and maintenance management.

Evaluation from users 

Comments from the principal of the base station:

We are very glad to cooperate with Shanghai Matis Electric Co.,Ltd. to complete the project transformation, From the early stage of the project, including data collection, field investigation, load estimation and project transformation, Matismart not only provides stable and reliable products- advanced intelligent terminals of the same period, but also found and dealt with many electrical faults in time.

 

The power distribution of base stations requires very high reliability. Every power failure directly affects the use of customers, causing serious economic losses. On the other hand, electricity safety and energy consumption are also very important parts in the power utilization of the base station. Some of the base stations are in remote areas, electricity delivery and timeliness are critical. However, Shanghai Matis Electric Co.,Ltd. has a unique strategy for monitoring and control in practical applications,after many times of communication, from the two directions of management and energy consumption, they proposed a solution suitable for our actual operation. 

 

Now, the system monitors the power utilization of the base station 24 hours a day, realizing the functions of power line management, intelligent analysis, electricity safety and electricity data monitoring in the project. The system can automatically quickly identify and alarm the abnormal electricity consumption. Meanwhile,the system realizes automatic timing management, electricity data detection and statistics, which is more convenient to promote advanced environmental protection concepts such as green electricity consumption and energy-saving control.
