Abstract :
A novel ride-through compensation scheme for an industrial mixer motor/drive system is presented during voltage sags. From d-q dynamic model of the electrical and mechanical processes, Simnon simulation equations are derived. A ride-through compensation scheme which exploits the surplus energy stored in the DC-link capacitor is introduced. An open-loop control volts per hertz boost strategy has been used in order to compensate the speed loss during the three-phase balanced voltage sags. Both compensated and uncompensated cases have been run and compared with simulation results. Experimental and simulation results shows reasonably good agreement.
