The authors propose a new diagnosis method for on-line broken bars detection by parameters estimation. For predictive detection, Kalman filtering algorithm has been adapted to take into account the on-line parameters deviations in faulty case. Within the framework of the diagnosis of the rotor defects, it is difficult to conduct experimental tests to validate the on-line identification of such default...
In this Paper, we present a systematically method based on the transformer coupling effect to establish the d-and q-axes equivalent circuits, which can describe the transient behavior of the synchronous machine. The MATLAB/Simulink Power System Blockset tools (PSB) is used for the simulation of synchronous machines by their equivalent circuits. One used an empirical method, based on the comparison...
In this paper, the authors propose a novel control strategy of active hybrid filters. The adopted hybrid filter consists of an active filter and a passive filter connected in parallel. The power rating of the converter is reduced compared with simple active filter. The control is introduced to allow active filtering of load harmonics and active damping of passive filter connected in parallel with...
