Korea manufactures turbines for remote mountain villages

By Kathie Zipp | May 27, 2010

Hanjin Ltd., a Korean manufacturer in the petrochemical industry and palletizing systems, has produced the HJWT1500, a MW-class wind turbine. The 1500/70 horizontal-axis turbine features a three-bladed upwind rotor with pitch power regulation and constant rotor speed, an asynchronous generator coupled directly to the grid, and an active yaw system. The 1500/77 upgrade has a 20% larger area. The 1.5 MW turbine has a speed of 3.5 m/s and a cut out speed of 25 m/s. Friction sliding bearings provide easy maintenance and robustness against strong wind turbulence. Fluid coupling is adopted for the power quality grid code and the system protection from overload at grid fault. A fast pitch system also provides enhanced power control performance.

Hanjin also offers the HJWT100/20 turbine with stall power regulation and two constant rotor speeds. The turbine includes a controlled electro mechanical break rather than a previous tip brake for easier maintenance. There is no misalignment during load change because of the in-line drive train without the offset of high-speed shafts. The turbine is specifically designed for Korean domestic topology such as islands and remote mountain villages.
