- Siemens will supply the technology for direct-current transmission
- Dragados partner is responsible for building and installing the offshore platform
- Six DC grid connections of the German North Sea were equipped by Siemens
Siemens has received another order from the German-Dutch grid operator, TenneT TSO, for a grid connection for offshore wind power plants in the German waters of the North Sea. The company will supply the entire technology for efficient direct-current transmission for the "DolWin6" grid connection. The Spanish partner, Dragados Offshore S.A., is a leading general contractor in the energy sector and is responsible for construction and offshore installation of the associated platform. The French supplier Nexans will supply the direct-current cables. TenneT tendered the supply and laying of the cables separately, and these services are therefore not part of Siemens' scope of supply. The order placed with Siemens is valued in high three-digit millions euros range. After it is completed, DolWin6 will be able to transmit enough electricity to supply just under one million German homes. Commercial commissioning is scheduled for 2023.
- Approximately 25 percent power/torque increase compared to previous series
- Good vibration and shock resistance
- Robust, torsion-resistant enclosure copes with harsh ambient conditions
The new Simotics DP roller table motors achieve outstanding power density coupled with a significant power/torque increase of around 25 percent compared to the previous series. The torsionally resistant ring rib enclosure and bearing plates are made of spheroidal graphite cast iron (GGG) and are designed for use under the harshest of mechanical ambient conditions. Together with their higher vibration and shock resistance of up to 3M6 in compliance with EN 60721-3-3, Simotics DP roller table motors are ideal for use in steel mills, in particular for rolling, reversing and transporting red-hot metal blanks under the highest levels of mechanical stress and extreme environmental influences such as scale, dust and water.

- Simotics Connect 400 enables motor operating data to be sent to cloud-based Sidrive IQ Fleet App without any structural modification
- Regular evaluation improves efficiency, optimizes serviceability and makes for an extended service life
In future, it will be possible for existing motors operating in the field to be retrofitted with the Simotics Connect 400 connectivity module from Siemens. This will allow size AH100 to AH450 low-voltage motors operated directly from the mains to transmit operating data straight to the cloud-based Sidrive IQ Fleet App without the need for any structural modifications. Regular data analysis allows plant operators to quickly and efficiently oversee the operational status of their drive systems and plan a servicing schedule based on actual requirement. This not only improves efficiency, but also optimizes serviceability and extends service life. Typical applications requiring monitored low-voltage motors include pumps, fans and compressors.
- The world’s first 1,100 kv transformer for the world’s largest HVDC project in China
- Development, manufacturing and testing in the lead factory in Nuremberg
- The world’s most powerful HVDC transformer with 587 MVA
The world’s first transformer, which Siemens developed and manufactured for high-voltage direct-current (HVDC) transmission systems with what is currently the highest transmission voltage of ± 1,100 kilovolts (kV), recently passed its type test. Siemens developed, manufactured and tested the HVDC transformer in its transformer factory in Nuremberg. It is the first of a total of seven ±1,100 kV transformers that Siemens and a partner company are building for what is currently the world’s largest HVDC transmission system. This type of transformer is among the most powerful single-phase units in the world, with a transmission capacity of 587.1 megavolt amperes (MVA). Siemens is building the transformers in its network of factories led by its Nuremberg plant, in cooperation with its factory for HVDC transformers in Guangzhou, China, as well as another Chinese partner. These factories are manufacturing the machines according to the specifications and documentation of the lead factory in Nuremberg. Commissioning of the world’s largest HVDC link – and thus also the transformers – is scheduled for 2018.
- Leading experts in latest HVDC converter and cable technology join forces
- India's first HVDC link featuring state-of-the-art VSC technology
- Transmission link to support Government’s Vision of 24x7 power for all
A consortium between Siemens and Sumitomo Electric Industries Ltd. has been awarded an HVDC order from Indian transmission operator Power Grid Corporation of India (POWERGRID) to supply a high-voltage direct current (HVDC) transmission system. The about 200 km long HVDC connection will be India’s first DC link featuring voltage-sourced converter (VSC) technology. VSC is the latest innovation in HVDC technology offering a very stable and highly flexible reactive power control independent of active power control and additional features to support the AC systems like blackstart capability. Furthermore, this solution is ideal to be combined with XLPE cable technology. Siemens will be supplying two converter stations with two parallel converters, each rated 1000 Megawatts (MW), featuring its VSC HVDC technology while Sumitomo Electric will be responsible for the XLPE HVDC cable system in the DC circuit. The combined order volume for Siemens and Sumitomo Electric is approximately $520 million. The grid connection is scheduled to go into operation in the first half of 2020.
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.
