Huawei Partners with Yunnan Power Grid for Advanced Communication Infrastructure

In a remarkable development for the energy sector, Huawei has joined forces with Yunnan Power Grid Co., Ltd. (Yunnan Power Grid), a pivotal energy hub in southwestern China, to construct a next-generation high-speed bearer network. This collaboration is a response to the increasing demand for clean energy transmission and the evolution of smart grid systems in the region. The geographical challenges and extensive transmission lines present in Yunnan have made this transformation not only essential but also complex.

As Yunnan Power Grid undertakes the transition towards smarter and cleaner energy solutions, the urgency for digital and intelligent upgrades in the communication infrastructure has escalated. The surging volume of production data alongside complicated service scenarios highlights an urgent need for a robust communication bearer network that can handle increasing demands effectively.

To address these pressing challenges, Yunnan Power Grid has adopted Huawei’s SPN (Service Provider Network) technology as part of its strategic plans, incorporated in both the 14th and 15th Five-Year Plans. This innovative approach allows the energy provider to progressively implement SPN technology across 16 cities, laying a strong communication foundation poised to support the region's energy demands for the next two decades. Notably, Huawei has emerged as a crucial partner in this significant upgrade of electricity services.

Enhanced Bandwidth and Efficiency

Since launching a pilot project in 2022, the SPN technology has evolved from a technical trial into a standardized network architecture throughout Yunnan. The deployment of SPN technology in Zhaotong and Pu'er has begun to unveil the full potential of this next-gen bearer network. One of the standout achievements is the resolution of bandwidth bottlenecks; the SPN network surpasses the previous capacity limit of 155 Mbps, enabling access bandwidth in substations and power plants to reach up to 1 Gbps, meeting the operational standards set by the China Southern Power Grid. Moreover, the aggregation and core layers can scale to 50 Gbps or 100 Gbps depending on site size and services provided.

The enhanced bandwidth facilitates high-demand services such as video surveillance and ensures smooth operations across the network. Furthermore, this upgrade has dramatically improved inspection and maintenance efficiency. The Huawei SPN solution allows for real-time Service Level Agreement (SLA) monitoring, enabling quick identification of faults and reducing maintenance time from over 7 hours to just 21 minutes in some instances, a reduction in the inspection time from 30 minutes to merely 3 minutes. In one notable case at the Qujing Power Supply Bureau, early detection of defects has been achieved up to 15 days in advance, significantly reducing the frequency of site visits needed from 112 to 61 per six-month period — a remarkable drop of 45.54%.

Supporting Diverse Energy Services

The Huawei SPN technology supports a wide range of electrical services. It accommodates latency-sensitive tele-protection and high-traffic video services with reliable transmission capabilities. By utilizing FlexE hard and soft slicing technology, the system ensures rigid service isolation and improves bandwidth reuse. Additionally, the dual-stack capability of IPv4/IPv6 provides flexible local forwarding and simplifies IoT access, allowing for efficient monitoring of transmission lines and the integration of resource-network-load-storage operations.

Lastly, this strategic deployment not only tackles current needs but also ensures long-term investment protection for the future. The SPN technology can evolve to support speeds ranging from 25 Gbps up to an impressive 400 Gbps through cost-effective upgrades, thereby minimizing the need for extensive re-constructions over time.
