Product Description Product Description As one of the core parts in the large-scale wind turbine control system, pitch control system plays a very important role in the safe, stable and efficient operation of the wind turbine. By adjusting the pitch angle of the blades, the pitch system changes the attack angle of the airflow on the blades, and then controls the aerodynamic torque and power captured by the wind turbine. The pitch control system from Shiyou electric adopts a series of redundant safe and reliable designs to ensure the safety, reliability and high utilization of turbine, it meets the requirements of plateau, high humidity, salt spray, ultra-low temperature and other operating environments, complies with the specification of Low Voltage Ride Through (LVRT) and High Voltage Ride Through (HVRT), and obtains the certification from CE, ETL and CGC.Key features:It has achieved multiple patents and software copyrights.Multiple redundant technologies for maximum safety, each pitch axis has been carefully designed to ensure the safe operation of each blade. Each blade has independent motor control, independent back-up power supply, independent control cabinet and cabling; integrated rotor speed measurement in active safety device.Complete system self-diagnostics to detect sensor faults, actuator faults and backup power failures.Complete drive protection with self-protection in the event of the following drive faults and upload fault information to the main control system: DC bus low voltage, DC bus overvoltage, drive over current, drive over temperature, power switch failure, abnormal internal power supply, brake resistor circuit failure, internal fan failure.It has perfect protection function for pitch motor, and the system can protect itself when the pitch motor has over temperature, over current, stall protection and abnormal braking faults, and can upload the fault information to the main control system.Low Voltage Ride Through (LVRT) and High Voltage Ride Through (HVRT) compliant.Drive, controller and charger in one unit.High efficiency, high power density, and heavy duty permanent magnet synchronous motors.Long life supercapacitors, safe and reliable backup power management, high-precision supercapacitor detection.Complete temperature control system, adapted to cold and hot weather.Monitoring key operating parameters of the pitch system such as current, temperature, etc. Intelligently analyzing the health of the pitch system.
