In this paper, a signal-based strategy is proposed for interturn short-circuit fault detection and isolation in Permanent Magnet Synchronous Machines (PMSMs). Usually, external disturbances or other faults may produce similar symptoms on signal-based fault detection strategies, thus producing false alarms. To avoid this disadvantages, the proposed strategy is based on measurement of the voltages at...
In this paper, a new strategy for interturn short-circuit fault detection and isolation in Permanent Magnet Synchronous Machines (PMSMs) is proposed. The strategy is based on the measurement of PMSM currents and voltages. The fault detection for any phase of the stator windings is performed from the analysis of a “vector residual” generated by a state observer. Furthermore, the rotor angular speed...
This paper presents a method for predicting the flicker level that is generated by the high-power load in a distribution system. Through the development of the Flickermeter that met the International Electrotechnical Commission requirements, a reference curve is obtained based on the variation of voltage and the amount of changes per minute of the load. The purpose of this prediction is to determine...
