In the traditional controller design, local signal is only chosen to be the feedback variable, and improvement of single performance in the system is considered. This way to design controller could make uncertain affect to other performance in the system. A comprehensive performance index is used in the coordinated control theory, and the controller which is more coordinated is designed. By using...
Commutation failure (CF) is a serious malfunction in HVDC systems. Fast detection and identification is important to avoid HVDC system block or even further deterioration of the whole system. This paper proposes a novel approach of CF recognition using wavelet transform and Shannon entropy technique. Only phase A voltage signal at inverter is used as the input of the new method. AC voltage is decomposed...
