Faults of wind turbine generator electromechanical parts are common and very expensive. This paper introduces a generator fault-tolerant control scheme for variable-speed variable-pitch wind turbines that can be applied regardless to the AC generator used. The focus is on generator stator isolation inter-turn fault that can be diagnosed and characterised before triggering the safety device. An ...

The work presented in this paper proposes an approach to reduce the common mode voltage at the output of matrix converters when a direct torque control scheme is employed to drive a permanent magnet synchronous motor. A mathematical analysis of the common mode voltage at the output of matrix converters is firstly carried out which is then corroborated by simulation results. Based on this analys...

This study presents an Optimized Wind Turbine Emulator (OWTE) based on a DC generator driven by three-phase Induction Motor (IM). The IM speed is varied using AC drive that converts fixed RMS voltage and frequency to variable ones due v/f control. reference of the control was calculated through optimized equations wind turbine model for maximum power torque. overall system simulated Matlab/Simu...

Pico hydropower plant is a generator engaged in the field of renewable energy, general, power system uses 3-phase synchronous with AC voltage, its development it can be used as converter, by converting voltage to DC voltage. One so that battery charger or discharger. An AC-DC also known rectifier, device for alternating current (AC) direct (DC). In many technologies industrial world utilize con...

AC 0 circuits of size n log n augmented with log n MODm gates, for every odd integer m and any sufficiently small . As a consequence, for every odd integer m, we obtain a pseudorandom generator, based on the MOD2 function, for circuits of size S containing log S MODm gates. Our results are based on recent bounds of exponential sums that were previously introduced for proving lower bounds for MA...

 A new adiabatic CMOS logic that operates from a single-phase power-clock is presented. A simple and efficient power-clock generator is integrated with the logic to generate the required AC power-clock supply waveform. Circuit performance is evaluated using a chain of inverters realized in 1.2μm technology. Experimental results show energy savings comparable to other adiabatic logic families t...
