One, Test Bench Performance Meets:GB/T10760.1-1989"Technical Conditions for Small Wind Turbine Generators"

II. Test Projects and Contents:

1Measure the winding's DC resistance under actual cold state.2Measure the insulation resistance between the winding and the housing.

3Stator insulation resistance test conducted; test voltage value:1200V Date:1Min

4Measurement of the Starting Torque Resistance of Generators (using weights): Under no-load conditions, there should be no fewer than one test point per revolution of the generator.3dot

5In no-load condition, adjust the generator to65%At rated speed, the three-phase AC voltage is measured using a digital voltmeter.Uab 、Ubc 、UacDirect current (DC) voltage after rectificationUdc；

6Voltage Regulation Test: At no load, the generator is set to the rated speed, and the line voltage of the three phases and the rectified voltage values are recorded; under load, the line voltage values of the three phases and the rectified DC voltage are recorded.

7Determining Generator Load Characteristic Curves: Testing the generator under load65%，80%，100.%，125%At rated speed, the generator's output power and measured efficiency at this point were determined using the direct load method (resistance load). A relationship curve was plotted with speed as the horizontal axis and efficiency and output power as the vertical axes.

8Efficiency Measurement: Utilizing the direct method, the generator is measured under rated voltage and power conditions. After the temperature reaches the basic temperature, input power, DC output power, current, thermal steady-state resistance are recorded, including the losses from rectification and connecting lines.
