Siemens is modernizing 15 converter transformers at the Cahora Bassa dam in Mozambique for the operator Hidroeléctrica de Cahora Bassa (HCB). The transformers form part of the HVDC transmission link built in the 1970s to transmit electrical power from the hydropower plant over a distance of 1,450 kilometers. The order volume is about €26 million, and the project as scheduled by Siemens will take three years.
As the global population experiences rapid growth, more people around the world are moving from the countryside to the city. In addition to the inner-city challenges posed by the urbanization megatrend, there is also an increase in the average traveling distance. As a result, the challenges for train systems are also increasing. To meet these demands, Siemens Mobility and Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) have jointly developed new auxiliary converters to improve the efficiency of on-board power systems using power semiconductors based on silicon carbide (SiC).
- Connect Box, part of Siemens Xcelerator, connects, monitors and operates small to medium-sized buildings
- Easy integration of wireless and wired devices into existing building automation systems, building management systems (BMS) or cloud applications
- Increases building operations efficiency, reduces energy consumption and meets regulatory requirements for sustainable and healthy buildings
Siemens Smart Infrastructure has launched
Connect Box, an open and easy-to-use IoT solution designed to manage small to
medium-sized buildings. The latest addition to the Siemens Xcelerator
portfolio, Connect Box is a user-friendly approach for monitoring building performance,
with the potential to optimize energy efficiency by up to 30 percent and to substantially
improve indoor air quality in small to medium sized buildings such as schools, retail
shops, apartments or small offices. Siemens Xcelerator is an open digital business
platform that enables customers to accelerate their digital transformation
easier, faster and at scale.
- An Avenio vehicle equipped with SiC technology spent one year transporting passengers in Munich and covered 65,000 kilometers in the process
- Energy use was cut by 10 percent and motor noise was reduced as well
- Joint research project conducted as part of the European development and research program PINTA
Siemens Mobility and Stadtwerke München (SWM) successfully completed a one-year test of semiconductor technology based on silicon carbide (SiC) in an Avenio streetcar in Munich in August. They have now presented the results of their research. The study found that the motor noise produced by the vehicle fell sharply and that energy use declined as well during the trips that the tram made on Munich’s public-transportation rail network. The semiconductor technology was produced by Infineon Technologies. The tests were conducted as part of the European research and development project PINTA. By taking part in the trial, Siemens Mobility significantly contributed to efforts to integrate SiC power semiconductors into rail vehicles.
- Potential reduction of more than 8,000 tons of CO2 annually
- Emissions and noise while berthed can be significantly reduced
- Sustainable solution contributes to climate protection
- 16-megavolt ampere shore power system to supply two ships simultaneously with certified eco-power
The Port of Kiel commissioned Siemens to build Germany’s largest shore power system to date. With a power of 16 megavolt amperes (MVA), the Siharbor solution will supply two ships simultaneously with certified eco-power, for the first time. This will reduce annual CO2 emissions by more than 8,000 tons. The system is expected to go into test operation within the 2020 cruise ship season. Maritime shipping plays a special role in Kiel. The port is the point of departure for cruises and has ferry connections to the Baltic states and Scandinavia. 32 different cruise ships stopped in 174 times at the port facilities in 2018.
- Siemens will supply four 400 kV HVDC transformers for cross-channel link
- Efficient 2,000 MW power transmission link between France and the UK will supply up to 3 million homes with electricity
Siemens will deliver four transformers, each with a capacity of 400 kilovolts (kV) and 315 megavolt amperes (MVA), on behalf of the British grid operator National Grid. The grid operator will replace the old transformers in the high-voltage direct-current (HVDC) cross-channel link. The new transformers are quieter, have lower transmission losses and will significantly improve the system's reliability. The HVDC link connects France and England and makes it possible to efficiently exchange energy in both directions. The order includes the supply, installation and commissioning of the transformers for the Sellindge converter station in England. Siemens will complete the work by mid-2019.
Siemens has received an order from the regional grid operator EWE Netz GmbH to supply the key components of a Siharbor shore power supply system in Cuxhaven. The order includes the complete transformer station as well as the cable feed system for ro-ro (roll-on/roll-off) ships. The plant owner will be the northern German Gesellschaft für Hafeninfrastruktur Niedersachsen Ports (NPorts). With a power output of 630 kilowatts (kW), the plant will supply these ships with electricity during their lay time. They will thus be able to turn off their diesel generators, significantly lowering exhaust gas and noise pollution. The berth is located next to the new factory for wind turbines operated by Siemens Gamesa, which will be the plant's main user in the future. Siemens Gamesa will ship wind turbine components to its sister factory in Hull, UK. The Siharbor system is expected to go into operation by April 2018.
