Low-cost, high-efficiency, remotely monitored 5kW variable pitch wind turbine
High safety-realized all-weather continuous unattended operation.
1. With all-time pitch controlled regulation, the rotor speed is controlled to ensure the continuous operation under adverse wind condition.
2. The whole system is more secure as it's doubly protected by the auto safety protection (ASP) system.
Higher electricity production-with pitch controlled regulation, the output is 30% more electricity generated.
1. Above rated wind speed, the blade pitch angle is passively regulated with continuous full power output.
2.The working wind speed interval is larger with 3-25m/s.

Technical innovation point
1.The world's leading centrifugal pitch controlled technology
(1) Big positive blade angle for initial(+9°), acceleration performance is excellent, start up at 2.5m/s low wind speed.
(2) Below the rated wind speed,high-efficiency output.
(3)Above the rated wind speed, regulate pitch angle, keep the wind rotor rotate speed nearby the rated rotate speed, stable output power.
(4)Continuously running when wind speed within 3-25m/s (cover land common wind speed) , no need to brake for protection.
2.Tilt-up tower makes installation and maintenance simple and convenient.
(1)Without crane when install wind turbine in remote regions or islands.
(2)Only need a chain block when maintenance wind turbine, simple and low cost.
3.Remote monitoring
(1) Real-time grasp the running state of the wind power system and electricity production data.
(2)The wind turbine can be started, stopped or operated by remote command.
Variable pitch wind turbine is a new type of wind power generation equipment, which has the following advantages:
1.
