Background

Grid modernization can deliver quantities of zero-to low-carbon electricity reliably and securely. A smart power grid is an electrical grid which includes a variety of operation and energy measures ranging from meters to controllers for data collection. Operators rely heavily on the timely data report that collected from the dispersed controllers and the IP cameras to make the right decision during the remote monito powring of line status, threshold warning and fault location for smart grid operation. In this scenario, the UR32 cellular router is widely used to minimize the cost of downtime and bring distributed sites online faster.

This router is favored in the Smart Grids architectures, in particular in the smart cities. It also provides services for the street lights, traffic lights applications, repower of electric cars, the electricity in buildings, and all the other electric applications.

  • Always-on M2M connectivity
  • Industrial-grade enclosure
  • Versatile and compact solution
  • Additional RS485 port, optional GPS and Wi-Fi support

Solution

Recently, Ursalink cooperated with The State Grid Corporation of China to fulfil a smart grid project successfully. The RS485 controllers, IP cameras and Ursalink cellular routers are working smoothly with smart meters and other devices in this solution. Because these devices have multiple LAN connection options – such as RS232 and RS485 –, a variety of WAN connection options (xDSL, fiber, 4G/3G and Ethernet) and even PLC connection options, it means the devices can work as a PLC base node while also providing advanced communications.

From the below topology we can see, when an abnormal situation occurs, such as the solar panel energy storage, the controller will forward the data to the cellular router via the serial port RS485. The additional RS485 serial port on UR32 cellular router connects with a controller through Modbus that allows for the conversion of the legacy protocol.

Since those devices are deployed on the remote areas, for the sake of the entire communications network and protect them from all kinds of attacks, they are fully supporting the most advanced security protocols, such as OpenVPN, IPSec, PPTP, L2TP, DMVPN, GRE, etc.

Operators are able to receive alerts and make response expeditiously depending on the accurate data that transferred from router when abnormal situation arose from the lines. And through the PoE interface, the UR32 router provides an out-of-the-box, secure, managed LTE network for the connected IP camera.

As a big quantity of these devices is required in smart grid project, customer needs a user friendly management tool or platform to greatly simplify the tasks of remote managing them, that’s way the Ursalink DeviceHub is free provided for customer.

Here, UR32 cellular router works as a cellular data packet forwarder and delivers all information to the monitoring center via 4G LTE cellular network.

This solution is efficient in line fault detection & location, threshold warning, reducing power outages and costs.
