wind turbine

The area of manufacture base of Tianjie Wind Energy is about 500,000 square meters. The workshop area is more than 200,000 square meters. The proportion of parts domestic manufacturer is above 90%. The control system is supplied by The Wind Energy Technology Institute. The advanced production equipment,the sophisticated detecting instrument and the strict quality controlling system make the products better.Developing with the Shenyang University of Technology,it possesses variable propeller pitch, speed and constant-frequency asynchronous generators that have independent knowledge property right.The design of impellers adopts the latest research results of aerodynamics and the optimized structures.The variable height and radius of wind wheels can be fit for different kinds of wind fields.The running condition was considered in the complicated climate condition in the disign of the WTGS.The transmission system adopts flexible support so that the transmission of system load can be stable.It can reduce effectively the operational noise of gear boxes and generators.The advanced variable propeller systems can furthest capture sind power,and reduce effectively the load of blades, transmission systems and fan's structural component so that it can prolong the working life of fans.It has the ability of traversing in the low voltage.So it can make fans maintain the grid connected condition even in the period of electrical disturbances.It has the poly-protection formed by dependent variable propeller pitch system and mechanical braking.Control system adopts self-developing special controller.It can fully use the wind energy and has the load optimized design.So the whole machine has the high reliability.
