    The stator flux model is different at high speed and low speed for the direct torque control (DTC), so the structure of DTC system is complex. Aiming at this issue, a new scheme of induction motor drive is proposed. The core idea is controlling the angle between the stator current vector and the rotor flux vector. It doesn't need the stator flux model. The system will obtain quick torque response ... View full abstract»

    A practical buses grouping method for weak voltage areas based on a fuzzy maximal tree clustering is proposed. Firstly, V-lambda curves of all buses are calculated by continuation power flow method. Then voltage magnitude variation is adopted to find weak voltage buses at the same load variation rate. After sorting the normalized DeltaV in a descending order, the bigger ones are chosen as weak vol... View full abstract»

    Wrong operation of transformer protection is always caused by magnetizing inrush currents. For safe running of a transformer, it is necessary to discriminate between magnetizing inrush currents and internal faults. Because the inrush current is a peaked wave with nonstationary component, the internal fault current can be distinguished from inrush current by the energy characteristics with time and...
