Smart Power Application Based on modem Networking

System industry situation

Power grid construction is complex and huge, the time span is long, and all kinds of new and old equipment are mixed in it, and many power grid structures are no longer the needs of today's social development, but the cost of power grid transformation is huge, not overnight. In case of natural disasters and other unknown damage accidents, it will pose a serious threat to the normal operation of the optical cable, and even the line will be interrupted, and the repair work is extremely difficult, and the time consumption is very long, which will have a very serious impact on the safety of the power grid and the normal operation of the equipment.

Nowadays, improving power quality is combining power grid transformation with new power grid construction from the source. For the newly built power grid, the first thing is to make a reasonable plan and use the latest science and technology to promote the network construction of power distribution automation.

Smart Power System Topology

In view of the problems existing in the power industry, some people rely on their rich experience in the Internet + industry, based on 4G/3G/2G cellular network access products, to build a set of basic solutions based on Internet + for the power distribution network industry market, to realize the intellectualization of the power distribution network, and to realize the Internet +. It effectively solves the problem of efficient, stable, and fast transmission of power data services, and is widely used in thermal and environmental protection industries.

System architecture

The whole system can be divided into three parts: acquisition terminal, communication terminal, and communication service center.

1. Acquisition terminal: mainly intelligent ring main unit, mainly including primary circuit, secondary circuit, switch cabinet, load switch, transformer, relay, contactor, and other equipment

2. Communication terminal: 4G lte cat 4 modem G786 is adopted, which can report the data of the power equipment of the client's acquisition terminal to the communication center through the 4G/3G/2G network, and also receive the telemetry, remote signaling and remote control signals from the communication center to control the terminal equipment.

3. Communication service center: Through the access of 4G/3G/2G lte cat 4 modem wireless data transmission terminal, the staff of the monitoring center can view the operation status of each device in real time, and can remotely carry out telemetry, remote signaling, and remote control. In case of equipment failure, immediately judge the failure point and send personnel for maintenance.

Advantages of the scheme

(6) The deployment cost is reduced, and the problem that the light deployment construction is difficult is effectively solved.

(7) Support short message configuration IP and port, Support remote configuration of all parameters.

Summary of the scheme

The intelligent power distribution network system provides a guarantee for users on power quality and power supply reliability. By adopting the distribution network automation scheme, the power outage time is reduced, the service level of power supply enterprises is improved, and convenience is brought to the power consumption life of the masses.

An intelligent power distribution network system solves the problem of backward power grid structure, which is one of the widely used solutions of the Internet of Things and can be applied to intelligent meter reading, intelligent distribution cabinets, intelligent transmission and distribution, and other industries.
