Today, the serious energy shortage gets exacerbated by explosive population growth and the resulting increase in consumption. Global communications networks comprise millions of communications sites. In cities, traditional energy and power supply systems not only have low energy conversion efficiency, but also consume a lot of power. In rural areas, power is generated by diesel generators with inherent problems such as low energy conversion efficiency, frequent fault occurrences, unstable communications services, and increased maintenance workloads. All this means high O&M costs for customers. As the cloud computing era comes, customers are focusing on finding the best ways to reduce power consumption and OPEX at data centers.
At Huawei, our goal is to bring high efficiency, energy savings, and environmental friendliness across the product lines to customers. This is precisely why Huawei is actively promoting industry-leading power supply solutions for communications networks and data centers. The carrier-class efficient power supply solutions provide modular power systems with a conversion efficiency of 96.8%. Green power supply solutions used in rural areas employ the latest energy technologies to schedule solar power, highly efficient direct current (DC) diesel generator (D.G.), and advanced cycle batteries (ACBs). This not only meets customer requirements for environmental protection and highly efficient operation, but also benefits customers as well.
With a modular design, the Huawei Carrier-Class Power Solution achieves 96.8% energy conversion efficiency, 41 W/in.3 power density, and high reliability. It supports smooth expansion and allows different power capability rectifiers, different efficiency units and different function units. Also, the zero-touch design and intelligent hibernation technology facilitate remote operations and management to provide secure and efficient green protection for data centers and communications networks.
The Huawei Hybrid Power Solution is the first green power supply system with a micro-grid energy system in the industry. This solution integrates a diesel generator (D.G.), an off-grid energy generation system scheduling renewable resources, an efficient energy storing system, and a remote monitoring and management system. Power generation systems can be scheduled and switched dynamically based on site requirements to supply constant green power, ensuring that services are not interrupted.
Nowadays, site power mainly comes from diesel generators. How to maximize their working efficiency has become a priority in the industry. The Huawei D.G. & Battery Hybrid Solution reduces fuel consumption by more than 50%. This solution uses an intelligent monitoring and scheduling system to schedule the D.G. and storage batteries based on the D.G. efficiency, load power, and battery capacity to ensure high efficiency by minimizing the D.G. usage. It has quickly become a preferred low-carbon power supply solution for traditional sites.
In order to use alternative energy to serve the needs of the population and promote economic development, Huawei has devoted many years of R&D efforts to alternative energy technologies and solutions. This has brought about the launch of an industry-leading alternative energy solution. The solution uses Huawei-developed energy scheduling system to schedule different power supply systems, such as the Solar Power System, Solar-D.G. Hybrid Power System, and Solar-grid Hybrid Power System, to maximize the use of renewable resources and cut carbon emissions.
Huawei’s green energy solutions are used worldwide by many leading operators including Vodafone, Telefonica, Telenor, Belgacom, MTN, Orange, T-Mobile, BT, Airtel, Etisalat, China Mobile, China Unicom, and China Telecom.
In addition, Huawei has provided efficient and clean green power for the sites in Greece, South Africa, and Pakistan based on the climate and load power to bring significant business benefits to customers. Huawei also has developed the Solar Power System for islands in tropical areas, balancing abundant sunshine with the disadvantage of poor transportation to supply clean and stable power while protecting the ecology and the homes of residents.
Huawei’s green energy solutions, which have been widely used all over the world nowadays, are supplying solid infrastructures for excellent networks.
