This paper presents a simple state-space representation of induction machine (IM) transients under stator winding inter-turn short-circuit fault. The mathematical development of this dynamic model is presented in detail and the differential equations are transformed into space-vector form for reduction reasons. The simulations of this transient model are conducted in MatLab script using ordinary differential...
Monitoring and fault detection of the electric machine drives through the stray fields are proposed in this paper. The frequency response of the stray electromagnetic field from several combination of machines is measured through low frequency antennas and signal analyzer. The proper algorithms are developed for the identification of the components, as well as the detection of some faults and failures...
this paper presents an application of a wavelet-based multi-resolution PID controller, for sensorless control of PM synchronous motor (PMSM). The procedure uses high-frequency injection. In this proposed controller, the wavelet package is used to decompose the error signal between actual and command signals into different frequency ranges. Consequently, a better estimation of position and speed is...
This paper presents an improvement technique for the power quality of the electrical part of a wind generation system with a self-excited induction generator (SEIG) which aims to optimize the utilization of wind power injected into weak grids. To realize this goal, an uncontrolled rectifier-digitally controlled inverter system is proposed. The advantage of the proposed system is its simplicity due...
