MHI Vestas V164

from Wikipedia, the free encyclopedia
Prototype of the MHI Vestas V164 on land

Vestas V164 is the name of a type of wind turbine developed for offshore wind farms by MHI Vestas Offshore Wind (until March 31, 2014: Vestas Wind Systems ) with a rotor diameter of 164 meters and a nominal output of 8.0  MW , 9.0 MW, 9.5 MW and 10 MW. This makes this turbine the type of wind turbine with the highest output (as of May 2019).

The prototype erected in January 2014 in the Danish wind turbine test field Østerild on a 133 meter high tower was also the highest wind turbine in the world until June 2016, when a 230 m high Nordex N131 / 3300 was erected in the Emmelshausen community . The total height to the blade tip in the 12 o'clock position is 220 meters. At the end of January 2014, the system fed electricity into the grid for the first time.

history

In March 2011 Vestas announced the construction of a new offshore wind turbine. With a rotor diameter of 164 meters, the turbine should have a nominal output of 7 MW. In October 2012, Vestas announced that it had increased the output to 8 MW, as it was hoping that it would improve profitability. The platform was designed for higher performance right from the start. In September 2013 Vestas announced that it would outsource its offshore business from its core business and operate it in a joint venture with Mitsubishi Heavy Industries . The reorganization took place on April 1, 2014.

In December 2014, the V164-8.0 was named "Wind Power Plant of the Year 2014" in the offshore wind turbine class by the specialist magazine Windpower Monthly . In 2016, a variant with a nominal output of 8.3 MW was also presented.

In January 2017 a variant with 9 MW output was presented. At this point in time, a prototype, the performance of which was subsequently increased, was already in operation. In June 2017, an increase in output to 9.5 MW was presented, for which only design adjustments to the gearbox and the cooling system were necessary. The version with 10 MW was presented in October 2018.

The core components of a wind turbine are the foundation structure, tower, nacelle, hub and rotor blades as well as the grid connection. The foundation and tower are selected site-specifically depending on the site conditions and are therefore excluded in the following. The actual components are rotor blades, hub and nacelle.

The rotor blades are 80 meters long and weigh around 35 tons each. They are made from glass fiber reinforced plastic . They are attached to the hub, which also houses the pitch drive , with which the angle of attack of the blades can be changed and thus the power can be regulated. Two hydraulic pitch motors are used per blade.

The machine house of the V164 is cuboid and, with a length of 20 meters, a height and width of 8 meters each. In order to provide mechanics with comparatively good accessibility to the system even during adverse weather conditions, it is equipped with a helicopter platform. The weight including the hub is around 390 tons.

The drive train, which consists of the drive shaft, clutch , a compact planetary gear and a medium-speed, permanently excited synchronous generator, is located in the machine house . In order to ensure that only torque is transmitted from the rotor to the gearbox and generator, the coupling is designed in a flexible "pure torque" design. The wind tracking system, which consists of ten servomotors, and the passive cooling system are also housed in the machine house.

In addition, large parts of the electrical system of the plant are found here. In addition to the generator, which generates 710  V alternating voltage , there is a rectifier in the rear area of ​​the nacelle with which the alternating voltage is converted into direct voltage. The DC voltage, designed as an intermediate circuit , is then passed to inverters in the tower , which generate AC voltage that is synchronous to the grid frequency for feeding into the power grid . With the help of this direct current intermediate circuit, an aerodynamically desirable speed-variable operation of the rotor is possible. The tower also houses the power transformer , which feeds into the medium-voltage network and can optionally transmit 33 kV to 35 kV or 66 kV, as well as the circuit breaker .

The system is designed for a service life of 25 years.

Location and yield

The Vestas V164-8.0 is approved for wind locations of class IEC S with mean annual wind speeds of up to 11 m / s with turbulence class B. The yield results largely from the wind speed achieved on site in combination with the wind distribution. Under local conditions, Vestas states an annual energy yield per system in the range of 30 million kWh at 8 m / s to around 45 million kWh at 11 m / s. In 2018, MHI Vestas announced that it would upgrade the turbine series by 2020 so that it can also be used in typhoon areas with the extremely high wind loads that occur there.

Prototypes

The prototype of the V164-8.0 was erected in January 2014 in the Østerild wind turbine test field in Denmark. After the nacelle had already been placed on the tower in December, the rotor blades were installed on January 14, 2014. The commissioning was announced on January 28, 2014. In 2016 the prototype was slightly modified and the nominal output increased to 9 MW. On December 1, 2016, after this increase in output, the system produced 215,999 kWh of electrical energy, i.e. H. fed into the grid with its full nominal power for 24 hours at a time.

Commercial use

In February 2014, Vestas received its first order for 32 wind turbines, which have been used in the expansion of the Burbo Bank offshore wind farm since 2016 .

In July 2014, MHI Vestas announced that the first four commercial series turbines would go into operation at an onshore location in western Denmark (Velling Maersk). Construction should begin in mid-2015, with the main aim of initially testing the installation and the operating and maintenance procedures of the systems on land. However, due to delays in the approval process, MHI Vestas has now withdrawn from the Velling Maersk project. Instead, two test facilities in the 16 MW Måde project were implemented under offshore-like conditions on the coast.

The first commercial offshore wind turbine was built in September 2016 for the expansion of the Burbo Bank offshore wind farm .

As of January 2017, firm orders had been placed for the system type for a total of 1.6 GW.
