Compensator for German grid

High speed, high content

Following the successful deployment of over 10,000 new 100GbE ports last year, Telia Carrier has launched its 400GbE- ready network. Both deployments feature Cisco cloud-scale routing technology. The upgraded carrier network uses Cisco NCS5500 series routers, providing a level of network density that enables more content streaming, gaming and connectivity. These services will be delivered at speeds between 1GbE and 400GbE. The ongoing standardization of 400GE coherent technologies is incentivizing new simplified, and partially disaggregated, IP over DWDM architectures. Staffan Göjeryd, CEO at Telia Carrier, said: “Conventional architectures and technologies, built on decades of accumulated complexity and yesterday’s truths, fall short in helping us keep up with customer demands for more consistent bandwidth and a high quality experience. This is especially true as more value is shifting to software; hardware cycles are becoming shorter and ongoing 400G standardization is poised to finally disrupt the optical networking market.”

ABB’s power grids business has completed its installationof ahybrid staticcompensator (Statcom) for the transmission system operator TenneT. The Statcom is located in the Borken substation in the federal state of Hessen, and was officially inaugurated in late-January. With its ability to combine dynamic and static reactive power compensation on a 30% reduced footprint, the solution will stabilize the German power grid by providing reactive power compensation and dynamic voltage support to maintain the grid at the required voltage. Germany is increasing its share of renewables, which grew in 2019 by 5.4% to 46%. The country is expected to continue the investment to reach its target of 65% of the country’s total power mix by 2030. As a result, a huge amount of reactive power will be needed to balance and stabilize the national grid as more centralized fossil power generation is phased out and replaced by more intermittent sources of energy. Much of Germany’s renewable power is generated in the north and east of the country, and transmitted in bulk to the south where there is a deficit.
