Hannover Fair this year introduced Siemens Energy intelligent solutions and environmentally friendly to produce electricity, transportation and distribution. Among the highlights of 2.3 MW of new wind turbines, low-speed gearless wind solutions for connecting offshore wind facilities in the technology of high voltage transmission direct current (HVDC) and charge point, which can carry electric vehicles with a rated capacity of lithium ion in an hour. They also presented new gas cells isolated and a prototype of 72.5 kV circuit breaker with a vacuum switch as the switching element.
For low wind speeds moderate Siemens Energy has developed a new generator for gearless wind power, which was presented in Hanover. The main generator SWT-0.3-113 2 is an innovative drive concept with a compact permanent magnet generator. This type of generator is characterized by its simple and robust, requiring no power for excitation and control, and do not slip ring. The result is a high efficiency even at low load. With a capacity of 2.3 megawatts (MW) and a rotor diameter of 113 meters, the new turbine is designed to maximize electricity generation at locations with low wind speeds moderate. It features the new Siemens blade B55 Quantum. This new blade design increases efficiency and optimizes performance. A prototype turbine Siemens new wind has been installed in the Netherlands in early March.
The CP700A load load point to recharge electric vehicles with a standard battery capacity within one hour. power load was doubled to 22 kilowatts (kW) of the new series, which in turn cuts charge time in half. In the vehicle is the fastest mode of operation with a three-phase AC voltage to a current of 32 amperes (A) and are therefore charged a higher power of 22 kW. The charge is also possible in both mono-and three-phase.
load point communicates with the vehicle leaving the cable to determine if electric cars borne the maximum current (32 A) or only at a reduced level of current (20 A). A standard IEC 62196-2 Type 2 connector is used for that. Load points can also be connected to a control center via Ethernet or a built-in GSM / GPRS modem, which means it is ready for remote monitoring and maintenance.
Using the example of the network connection of offshore wind parks DanTysk, which will form part of the wind farm Sylwin cluster in the North Sea, Siemens in Hanover showed how effectively wind farms can be connected to the network usage the position of offshore platforms. DanTysk is built west of the island of Sylt and will have 80 wind turbines with a combined capacity of 288 MW Siemens. A Siemens HVDC Plus system is installed on a station platform at sea with the transformers and switchgear gas-insulated high-efficiency high-voltage transmission of electricity generated by wind farms in the group with the mainland. Siemens provides this offshore wind power switching (WIPOS) technology on a floating platform for self-elevation, which is derived from its place in the sea with sea-going tugs
Siemens is also present in a new generation of air insulated equipment NXAIR. The experts considered the draft of an existing production line, which aims to develop a preliminary concept for distribution throughout the world and bringing to market. The result is a factory-installed, approved according to IEC 62271-200 switchgear unit, which IAC FLR internal classification of the arc, the activities of LSC-2B class and the availability of the lining of Class PM (metal-clad). NXAIR units under classification covers the range of 17.5 kV ≤ 40 ≤ kA ≤ A. 4000, under the basic concept of the framework can be produced as well as the Siemens factories in Africa and Asia, and the plants in America and Europe and are available worldwide.
The newly developed device high voltage introduced by Siemens in Hanover included a new variant of the range of gas insulated switchgear 8DQ1. This cut is particularly compact design with a rated voltage of 420 kV, with a short circuit current of 63 kA and a rated current of 4000 A. The device operates with a single-break circuit-breaker with a break of less than two periods. Under the compact design of newly developed device is adapted to be deposited in places where space is not sufficient for a gas in common units of high voltage isolation with the notes - a decisive advantage in the urban electricity network extensions.
With a prototype of a vacuum breaker and a design studio on a 145-kV vacuum interrupter Siemens demonstrated in Hanover that the technology of vacuum breaker does not stop at 52 kV, but is also technically possible to deploy network. With 40 years experience in the production of vacuum interrupters for medium voltage and over three million units supplied Siemens launches proven technology for high voltage level. The vacuum-breaking series will meet the same quality as switches Siemens gas-insulated high-voltage and will also be of modular design. The prototype of 72.5 kV vacuum circuit breaker has been tested in a complete series of approvals in accordance with the current version of IEC 62271-100. Some of the switches in this series is already installed for prototype testing and studies in European networks.
Directs the point load behavior can be controlled remotely to support the implementation of an intelligent network.
The alternating current produced by wind turbines will be converted into DC on the platform, which will then be placed directly next to the wind farm in the North Sea. The DC will be brought to a transmission voltage of 320 kilovolts (kV). The power will then be sent to the low loss feed network developed on the coast, where electricity is converted from alternating current to a converter station.
They will be launched following the successful completion of practical studies.
