Siemens Gamesa Renewable Energy (SGRE) has introduced a new onshore wind platform: the SG 5.X, which encompasses two turbine models, the SG 5.8-155 and SG 5.8-170.
With a rated power of 5.8 MW, the platform introduces the largest unit capacity and largest rotor diameters – 155 and 170 meters – in the company’s onshore portfolio. SGRE says this results in maximum performance in high-, medium- and low-wind conditions.
Compared to the SG 4.5-145, the SG 5.8-155 expands the swept area by 14% and annual energy production (AEP) by over 20% (at a wind speed of 8 m/s). Further, compared to the same turbine, the SG 5.8-170 provides an increase of over 37% in the swept area and more than 32% in AEP (at 7 m/s).
According to the company, the new turbines integrate the hallmarks of SGRE technology, including a doubly fed generator, partial converter and compact drive train with a three-stage gearbox. Additionally, an optional premium converter ensures compliance with grid-related connection requirements.
“The new Siemens Gamesa 5.X’s high and flexible power rating coupled with the two rotor options make this platform suitable for any kind of site across the globe,” says Mark Albenze, onshore and service CEO at SGRE.
The first prototype installation of the SG 5.8-155 is planned for mid-2020, and production is scheduled to commence in Q4 2020. For the SG 5.8-170, the first prototype is planned for Q3 2020, and production will start in Q1 2021.
Windpower is expanding in the Dakotas and Wyoming. Large turbines such as this and the new GE can be useful in these areas if the designers keep in mind the local conditions. For example North Dakota can have 20 foot high snowdrifts. Keeping roads plowed to service wind turbines can add to maintenance costs. If these turbines were equipped with helicopter landing pads similar to offshore turbines, maintenance can be done cheaper. I am curious to know if any of these larger turbines are equipped with helicopter landing pads. By the way this morning I watched a helicopter crew inspecting… Read more »
