Abstract: | The 500‐kW wind generator was developed as one of NEDO's projects, and it has been operated at TAPPI wind park since October 1996. Since then, several tests on its performance have been made. One of the most important characteristics concerns the dynamic behavior under fluctuating wind conditions. For this purpose, we performed the modeling of the NEDO 500‐kW wind generator by a system identification technique using the measured data. Next, we clarified the basic characteristics such as transient response and frequency response of the generator based on the model. We confirmed that the simulated results of dynamic behavior almost agree with the measured results. © 2001 Scripta Technica, Electr Eng Jpn, 135(3): 37–47, 2001 |
