Product Description：
The WFD800plus wind turbine fault testing platform is developed for simulating and testing various common mechanical and electrical faults in wind power generation systems. Parallel gearboxes, planetary gearboxes, rolling bearings, generator fault simulation, sensor faults, etc. can be conducted to enable researchers and technical developers to gain a deeper understanding of fault characteristics and impacts.
Configuration：
The test bench system mainly consists of a cast iron platform, a reduction drive motor, a planetary gearbox system, a parallel axis gearbox system, a dynamic torque sensor system, a torque load system, a generator (installed interchangeably with the torque load system), a protection system, a test bench control system, a double support bearing unit, an adjustable resistance energy consumption system, a simulated blade wind tower, etc. In addition, it is important that the magnetic powder load brake can be connected to the gear transmission system, so that the output torque of the magnetic brake can be freely controlled through current regulation.
Function：
Conduct simulation experiments on common rotor mechanical faults, such as shaft misalignment, rotor imbalance, and loose mechanical foundations.
Research on the fault mechanism of parallel axis gearbox: Different fault forms of straight teeth, such as pitting, wear, cracks, broken teeth, missing teeth and other common faults, can also be customized according to needs.
Research on Rolling Bearing Faults: Different forms of faults in the internal bearings and supporting bearings of gearboxes, such as bearing inner ring faults, bearing outer ring faults, bearing cage faults, bearing rolling element faults, bearing comprehensive faults, etc.
Research on planetary gearbox faults: sun gear, planetary gear, large ring gear, fault types, missing teeth, wear, broken teeth, cracks;
Generator fault research: In conjunction with current and voltage sensors, different faulty generators can be optionally paired. Can study generator rotor, generator rotor imbalance fault, generator bearing fault, generator rotor bar breakage fault, generator turn to turn short circuit fault, generator voltage imbalance phase loss fault.
Can simulate mechanical faults and generator electrical faults;
Can research fault signal feature recognition and signal characteristic processing;
Simulation of different working conditions: gear characteristics under motor acceleration and deceleration states, gear characteristics under different load states, etc.
