Building a Highly Reliable Power Optical Communication Network

In recent years, as the electric power industry ramps up digital transformation and focuses on building smart grid, digital technologies and physical power grids need to be closely integrated to empower energy transformation and improve power grid digitalization. To achieve this, the electric power system needs to leverage advanced digital technologies for coordinating various sensing devices. Adding a large number of sensing devices will inevitably lead to a significant increase in traffic. To cope with this increase in traffic, the power transmission and transformation communication network needs to be upgraded to provide higher bandwidth.

Huawei electric power optical communication network solution for power transmission and transformation provides secure, stable, and reliable transmission channels for production and management services in the electric power industry. This solution for power transmission and transformation carries OT and IT services in a unified manner, and uses the next-generation technology fgOTN for SDH evolution, supporting long-term evolution of communication networks for electric power companies.

The MS-OTN platform is used to provide a unified bearing platform for electric power companies to carry production and management services. The 100% physical isolation technology is used to carry different types of services through different timeslots. These services are isolated from each other to ensure high service reliability and stability. Multiple protection schemes are provided to improve the reliability of power grids. fgOTN is applied to support the long-term evolution of power communication networks. The ultra-long-haul transmission capability enables electric power systems to adapt to various environments.
