Three fiber glass reinforced blades are bolted to a rigid hub, that mounts directly onto the generator main shaft. The turbine rotor is protected from over speeding by electronically controlled blade pitch drive motors.
It has a stationary stator and permanent magnet rotor. The optimization of the generator, endeavors to minimize losses and maximize the power factor.
Quality Power
The Palmtree 300kW WIND TURBINE provides reliable power in distributed generation for African conditions, where the power grid is many times “soft and unbalanced”. Our variable speed, direct-drive permanent magnet multi-pole generator, with its integrated power converter increases energy capture while eliminating current inrush during control transitions. The turbine can connect to large power grids as well as to remote wind-diesel mini grid systems. It effectively provides grid support, without inducing surges, rather than compromising the quality of the generated electricity supply
Reliability
Our sophisticated remote monitoring/control software allows real-time accessibility of the turbine thus minimizing unnecessary service calls. The entire system for controlling the supply of the generator output, including the AC/ DC/ AC converter is stationed inside the base of the tower. The bearings of the turbine form an integral part of the generator which reduces the necessary maintenance work to the grease lubrication of its slow-speed bearings. The bearings absorb the forces of the rotor and at the simultaneously functions as bearings to the generator.
Simplicity
The focus of the design was simplified by reducing the number of components used to as few as possible. The Palmtree 300 wind turbine functions without parts such as a gearbox, intermediate shafts and couplings, which are failure-prone and need extensive maintenance. Trouble-free operation of the wind turbine is maintained by the gear-less multi-pole generator with permanent magnet excitation, as passive air-cooled system. This uncomplicated rotor design allows safe, efficient turbine operation.
