Power Distribution Automation Communications Solution

Huawei Power Distribution Automation Communications Solution for grid communication services on dedicated or public, wired or wireless communications networks.

An ICT Solution For Reliable and Quality Power Grids

A power grid’s reliability and quality directly impacts economic activities and residents’ daily life. While an automated distribution network solves essential problems in linking power supplies with demand, older grids make this difficult:

• Aging devices and lines, and improperly distributed grids cause high line loss and low power quality

• Without Distribution Automation (DA), grid devices cannot be effectively monitored, and grids have weak self-healing capabilities

• DA’s many devices and complicated scenarios require high communication reliability and low latency. Huawei’s solution, with leading ICT technologies such as xPON, eLTE, industrial Ethernet switches, and GPRS/3G, makes DA possible on existing grids.

Huawei’s solution, with leading ICT technologies such as xPON, eLTE, industrial Ethernet switches, and GPRS/3G, makes DA possible on existing grids.

  • xPON-based dedicated DA communications network solution
    Recommended for urban areas that have optical-fiber resources such as CBDs, and for high-tech industrial development zones

    • Active/standby failover and independent dual-uplinks provide reliable DA services in areas with heavy power loads

    • Comprehensive security for DA services with features such as prevention of eavesdropping and MAC spoofing

    • Maximum communication bandwidth of 2.5 Gbit/s over a distance of 20 km enhances DA service transmission

  • eLTE-based, dedicated DA communications network solution
    Recommended for urban areas such as old residential areas with no resources and unfavorable conditions (for example, difficult site acquisition and high costs) for installing optical-fiber resources. This flattened IP network architecture reduces the number of network nodes and reduces latency:

    • Without optical-fiber resources, eLTE can still expand capacity by deploying additional CPEs and updating service data, thus simplifying network construction and maintenance

    • QoS-controlled dynamic bandwidth allocates resources based on priorities, ensuring the smooth operation of mission-critical services such as relay protection and remote control

    • Two-way authentication, UTRAN encryption, and signaling integrity protection measures ensure the reliability and security of the communications network.
