Increasing Frequency Capability of PMSM Vector Controlled Drive for Pumped Storage
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2014, Vol 38, Issue 38
Abstract
The subject of this paper is a comparative study between two supply modes of a permanent magnet synchronous motor (PMSM). The goal is to obtain a better efficiency for a hydraulic pump drive system. The machine (PMSM) is operated in vector control mode. The inverter is controlled with a sinusoidal pulse-width modulation (SPWM) technique. The study will allow to increase the root mean square (RMS) of the voltage and hence speed, avoiding over-modulation. The comparison is also made between third harmonic injection and over-modulation.
