The BENZ PMG DD 900kW wind turbine’s configuration uses an innovative direct drive design (no gearbox) in conjunction with a permanent magnet generator with the end result being a significantly increased reliability for the system as a whole. This type of set up reduces the overall weight in the nacelle and requires a rotor speed which is significantly lower (13rpm -33rpm) than that for a doubly fed inductor generator designs using old-fashioned gearboxes which usually need bearing changes after 5 years of operation. All of this means that the BENZ PMG DD 900kW turbine powertrain is more reliable, has fewer moving parts to go wrong, and requires much less maintenance than conventional gearbox equipped turbines.
The result of the direct drive – permanent magnet technology is a system which significantly increases reliability and reduces maintenance costs. Reduced downtime for maintenance also means less non-producing time offline. The elimination of associated mechanical losses that are inevitable with gearboxes also leads to improved efficiencies in the power conversion process.
The BENZ PMG DD 900kW generator itself is also much more robust than conventional systems and gives greater efficiencies when wind speeds are not at full rating, compared to the earlier conventional designs.
The BENZ PMG DD 900kW can be installed as a single unit on- or off grid wind turbine system or combined as multi-units building an on-grid independent wind farm connection.
The BENZ PMG DD 900kW wind turbine – with a tower hub heights available of 50m and 75m guarantees excellent yields in the 900kW category at inland sites.
With cut-in wind speed as low as 3m/s, the direct drive technology enables the turbine to make efficient use of the prevailing wind conditions at the respective sites to produce sufficient electrical energy. This machine is most suitable to supply electricity for factories, feed the local grid, low cost upscaling and addition to existing wind farms and onshore projects.
The BENZ PMG DD 900kW has maximum operating efficiency without increasing operating loads in the full and partial load ranges and at the same time prevents undesirable output peaks thus guaranteeing excellent yield and a high quality of power fed into the grid. This turbine is a flagship of the latest wind turbine precision technology using rigid and high-quality components.
