Today‘s wind energy markets demand higher yields and greater efficiency from wind energy plants in operation. This necessarily leads to an increase in the diameter of the rotor.Wind turbines is reacting to this demand with the introduction of its new Wind turbinesD9. Years of experience in the design of high-yield, lightweight turbines are being brought to bear in this launch.
The Wind turbines D9 series will be available with a rotor diameter of 93 meters, hub heights of 80 or 100 meters and a nominal output of 2 megawatts. Based on the experience gained with the Wind turbines D8 family, a range of different design concepts will be offered to suit different markets.
The Wind turbines D9.0 with asynchronous generator and converter is designed for 50-Hz markets. This type of design is very common in the wind energy sector and can draw on a wealth of experience.
The unit delivers electricity of a high quality and with a high degree of network compatibility.
In view of increasing demands on the part of grid operators in relation to the grid compatibility of wind energy converters, the role of synchronous generators in the wind energy sector is of growing importance.
Wind turbines for different markets.
The Wind turbines D9.1 is intended for international markets, with models suitable for 50 or 60-Hz grids. The turbine is equipped with a three stage gearbox, a permanent magnet synchronous generator and an IGBT pulse width converter. It is characterized by increased network compatibility and better yields compared with the Wind turbines D8.0. It is offered as an alternative to the Wind turbines D9.2. Based on the Wind turbines D8.2, the Wind turbinesD9.2 is offered on international markets in versions suitable for 50 or 60-Hz grids. The unit achieves extremely high availability levels and improved network compatibility. Both the Wind turbines D9.1 and the Wind turbinesD9.2 are particularly effective at meeting the network stabilizing requirements demanded by grid operators using a high proportion of renewable forms of energy
