The Switch, a Finland-based supplier of permanent magnet generator (PMG) and full-power converter (FPC) packages for wind turbines, says its first 5 MW high-speed drivetrains have been installed in China.
The installation was performed for CSIC (Chongqing) Haizhuang Windpower Equipment Co. Ltd. (HZ Windpower), a Chinese wind power equipment manufacturer. According to The Switch, the turbines operate continuously at 5 MW.
The new Haizhuang PMG5000 generators and FPC5000 converters have been designed especially for Haizhuang by integrating The Switch's 6 Switch Drives. The Switch PMGs and FPCs have been designed to operate reliably in the harsh offshore environment, the company says, adding that the converter is installed inside the tower’s base floor, which is about 12 meters above sea level.
