PROMOTED CONTENT Power companies are building new networks that must support diversified services yet remain highly secure. Huawei offers a one-stop ICT solution for the electric power sector, writes Chen Chun-Yi. The company’s fully-connected grid solution has served 13 of the world’s top 20 power companies, including Eon in Germany and Enel in Italy. Another recent customer is SAK, the largest power company in Eastern Switzerland.

Due to the expansion of global power grids in recent years and with more service types and higher bandwidth requirements, the power transmission and transformation network is in the peak of construction. However, traditional low-speed services such as SCADA and relay protection have existed for a long time, and their security level is high.

This is why power companies need to have highly reliable power transmission and transformation networks. On the other hand, more and more electric power companies are developing new services based on rich network resources. In addition to the original production and operation services, communications networks could tap in to a large number of value-added services.

Power backbone

In the new era of intelligence and big data, can the existing power communication network bear diversified service requirements? Which and what kinds of the technologies can better support future development? How can the network be deployed to drive growth for power companies?

Founded in 1914, SAK is the largest power company in eastern Switzerland. Its power supply covers 470,000 users and the transmission network has 2000+ km of optical fibers. In addition to providing power services, SAK provides bandwidth leasing and video TV services. With the expansion of new businesses, SAK chose Huawei to build an intelligent, efficient, and reliable transport network for its smart grid construction and expansion.

SAK collaborated with Huawei to build an intelligent and reliable power backbone network using OSN 9800 and OSN 1800. This solves three challenges including network simplification, future orientation, and continuous growth. This solution has three major values, perfectly addressing the development difficulties of the electric power network:

Multiple technologies are converged to simplify network layers:It leverages the MS-OTN architecture to provide a one-stop solution to satisfy the complex bandwidth and interface requirements, reducing device stacking and simplifying networks.

Future-oriented evolution and seamless interconnection of services on the live network: The existing power systems and services are seamlessly compatible with each other and meet the requirements of IP-based and intelligent transformation in the future.

Mobilized optical fiber resources to boost revenue growth:Supports single wavelength 100G/200G. A pair of optical fibers implements 20T ultra-large bandwidth, meeting the digital bandwidth requirements of smart grid informatization. In addition, the network infrastructure resources are reactivated to achieve continuous value increase.

Flagship product

For the electric power industry, Huawei provides a one-stop ICT solution and puts forward “new ICT, bits drive watts”. Huawei is committed to bringing digital technologies into every home and each electric power enterprise and becoming the best partner in the digital transformation of the electric power industry.

To date, Huawei’s fully-connected grid solution has served 13 of the world’s top 20 power companies and has been widely used in 73 countries worldwide, serving more than 190 electric power customers. Some examples of customers it already serves are State Grid Corporation of China (SGCC), E.ON in Germany, and ENEL in Italy.

OSN 1800 V, as a flagship product of the Huawei’s next-generation Universal Transport Solution for Smart Grid, not only supports large bandwidth and MS-OTN features, but also innovatively integrates the WDM, MPLS-TP, SDH, and PCM functions, providing a one-stop solution for complex power transmission and transformation.

It will effectively optimize the communications network architecture, improve the security and stability of the power grid, and further release optical fiber capabilities to provide reliable assurance for the development of smart grid construction and continuous operation.
