SWT-60kw wind turbine,wind turbine for home-Senwei-China best wind turbine,wind turbine manufacturers
Main Parameter:
60kW variable pitch wind turbine is a medium-sized wind turbine with the latest advanced technology. The previous market of medium-sized wind turbine like 50 kW 60kW 100kW is blank. Nobody produces this kind of product. With the increasing market demand this recent year, this kind of medium-sized wind turbine represented by 60kW wind turbine is becoming more and more popular.Because it does not need to occupy a large area of land like megawatt wind turbines, the 50kW wind turbines will be more convenient to install.
SWT-60kw variable pitch wind turbine is the low-speed type of wind generator, which adopts wind speed sensor and wind direction sensor to realize control blade pitch distance variable at the rotor and automatic adjust itself if when it is super-wind or over-voltage. It is of high power generation efficiency, convenient of maintenance, high reliability and no need for people to operate all the time, and thus saving cost, reducing the loss and obtaining high benefit.
SWT- 60KW wind turbine generator set includes wind turbine body, the generating part (generator, active variable pitch brake system,slip ring, direction-adjust device), tower, anemoscope, dogvane, intelligent controller etc.
For the wind turbine, the ball hub and airfoil blade with FRP in material are adopted. It is of elegant sculpt, high lift-to-drag ratio, excellent performance. The GBS intelligent hydraulic system is applied to buffer the blade inertia and the wallop to the tower. In the hydraulic slewing motor system, the hydraulic oil transfers the motility, so it is smooth startup and reliable working. In addition, various sensors can identify wind speed, rotating speed, current, temperature, vibration, twist etc. Intelligent adjustment by the control of PLC achieve the function of below, namely self –direction adjustment, self untwist, over rotating speed protection, over current protection, over wind speed protection, minus power testing.
Timely cut in or cut out, when it is overload, electricity network supply failed or the wind or failure of wind turbine itself, it will stop automatically.

Fail safe brake systems
Safety is ensured by dual fail-safe braking systems; one aerodynamic brake and one electromechanical disc brake on the main shaft. There is special brake device that is turning angle of blades to minus direction while tighten steel braking wire. Wind force to wind blades generate a counterforce so that decrease slowly spin speed of blades to regulate speed and stop rotating, it can be automatically operation, also can be operated by manual.
Remote operation
All systems are controlled by software; therefore remote control of operation and maintenance is possible ensuring high availability and few visits to the site, as well as monitoring wind utilization for optimal production.
Silent operation
The blades have been carefully designed in accordance with the latest technology. Made in carbon fibre reinforced resin with a thin and sharp rear edge, the blades move through the wind so smoothly you can hardly hear them.

Attention:
start-up wind speed 3m/s; security wind speed sets 20m/s;
automatic model working logic: wind sensor detects wind turbine > start-up wind speed, system start yaw mechanism automatic to face wind direction, wind turbine start to work; wind turbine rotate speed, output voltage, output current and output power > setting value of pitch mechanism start to pitch up (each action around 3°); when wind speed decrease wind turbine will pitch down working, keep the best blades angle to catch wind, to keep wind turbine generating the most electricity condition; when network failure, or wind speed> security wind speed, or any malfunction happens,or electro-magnetic braking start-up, or system stopping, wind turbine pitch up to limited location; yawing system starts (wind speed> start-up wind speed), to make axis line of wind turbine 90°to wind direction, decrease speed to brake, wind turbine stop working to protect system securtiy.
