Installation of the HQ5500/140 prototype is planned for mid-2013. The company plans to market the product in two distinct stages. The first stage focuses on the domestic market, to be followed by a North European market in a second and final push. Commercial availability is scheduled for early 2014.

HHI and AMSC have previously collaborated on the 1.65MW (pictured) and 2MW wind turbines

Developed for both onshore and offshore applications, the HQ5500/140 concept follows AMSC design principles known from the company's earlier, smaller turbine models.

The variable-speed pitch-controlled HQ5500/140 model features a three-blade rotor with 140-metre diameter and rated wind speed is quoted at 11.75 m/s.

Power rating

A specific power rating of 357W per square metre gives a medium value in between a current range of around 300-380W per square metre found for several recently introduced and announced 4MW+ offshore turbine models.

The compact drivetrain comprises a cast main carrier as main structural element. It incorporates a flanged three-stage gearbox and main shaft that comes as a semi-integrated assembly, while a high-speed generator is mounted on a separate bolted-on generator frame.

AMSC offers a choice between a permanent magnet generator (PMG) and a doubly fed induction generator (DFIG). HHI selected the PMG option, which comes with a full (100%) power converter.
