At last week’s Cigre exhibition in Paris, Huawei and Kenya Electricity Transmission explained how a universal transport system could break transmission bottlenecks in smart grids.
The two companies provided an analysis of the key factors of power communications network construction. These include power transmission and transformation service bearing, backbone communications capability building, network infrastructure resource monetisation, and a continuous profit-making business model.
Huawei also officially released its UTS universal transport system for smart grids.
The rapid expansion of the global power grid is driving a spike in the construction of power transmission and transformation networks that have greater requirements for more types of service and higher bandwidth. Traditional low-speed services such as supervisory control and data acquisition (scada) and relay protection will continue to exist for a long time, providing high levels of security.
Against this backdrop, it is essential to ensure the on-going high reliability of the power transmission and transformation network. In addition, an increasing number of electric power companies are leveraging rich network resources to explore new services. Apart from the original production and operation services, value-added services are flooding into communications networks.
To help electric power companies develop simple, future-oriented networks with continuous value growth, China-based Huawei’s UTS integrates OTN, SDH, packet, PCM and other technologies based on the MS-OTN architecture. A single wavelength can reach 100 or 200Gbit/s, and a pair of optical fibres can achieve a bandwidth of 20Tbyte. This enables power transmission bearer networks to allow unified access of multiple services from backbone networks and access devices, simplifying networks and unifying devices.
This meets the bandwidth requirements of smart grid informatisation and digitisation, and revitalises network infrastructure resources for continuous business value growth.
“Kenya’s power transmission network is expanding rapidly,” said James Gordon Kwanya Rege (pictured left), chairman of Kenya Electricity Transmission. “With the fast development of digitalisation and need for business monetisation, there is an exponential growth in demand for backbone bearing network bandwidth. Hence, electric power companies need a bandwidth solution that caters to long-term growth evolution and flexibility in capacity expansion. Now with the release of new equipment, I am even more confident about Huawei's innovative capabilities in the optical transmission field and our future cooperation.”
The OSN 1800V smart grid universal transport flagship supports immense bandwidth and MS-OTN features, and also integrates multiple functions such as the WDM, MPLS-TP, SDH and PCM. This is said to be a one-stop for complex power transmission and transformation.
"The electric power industry has special requirements,” said Joe Zhou (pictured right), vice president of Huawei. “For example, there are high transmission interface and performance requirements – including delay and jitter – associated with the transmission of relay protection signals on the power transmission and transformation network. After years of application, PCM devices with low-speed interfaces and SDH-based physical hard pipe technology have proven to be the most suitable technologies and cannot be replaced by other technologies. It is evident that the MS-OTN is the best for bandwidth acceleration and network value addition."
He added that listening to customers, gaining in-depth customer understanding and meeting customer requirements were the keys to providing leading power industry offerings.
"The application of Huawei next-generation universal transport solution for smart grid will further unleash optical fibre capabilities and provide reliable assurance for smart grid construction and development, as well as continuous operation for value growth,” said Zhou. “Looking ahead, Huawei will continue to provide customers with leading optical transmission network solutions, innovate technologies based on customer requirements, and work with industry partners to promote network cloudification and digital transformation."
Huawei provides the electric power industry with one-stop ICT to bring digital technologies into homes and electric power enterprises. To date, Huawei's fully connected grid product has been implemented by 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, including State Grid Corporation in China, E.On in Germany and Enel in Italy.
