Özet

Voltage dips are the most harmful disturbances which may affect the voltage stability of wind turbines. In these voltage dip conditions, stator/rotor currents and electrical torque increase to fairly high values with failing of voltage stability. In order to provide voltage stability after the faults of voltage dips, the faults must be compensated fast and accurately. The main contribution in this study is that missing voltage technique (MVT) based controller method is tested in dynamic voltage restorer (DVR) to mprove fault ride through (FRT) capability in grid connected wind systems. The proposed method controlled DVR is performed for symmetrical and asymmetrical faults in grid connected wind energy systems by using PSCAD/EMDTC power system simulator program. The case studies demonstrate the superior and effective compensation results.
