Control of a Permanent Magnet Synchronous Machine (PMSM) connected to an unbalanced electric grid


The quality of the electric power produced, transported and distributed did not cease being a major concern for the operators and the manipulators of electricity. Several disturbances of various natures are at the origin of instabilities of the electrical supply networks]. Among the disturbing phenomena, we quote the unbalance voltage of which we were interested by proposing an adequate command and control of a Permanent Magnet Synchronous Machine (PMSM) when this one output on the network. In fact, the unbalanced electrical grid voltage has due direct to the earthed grids which are connected to it. This unbalance has harmful effects on operation of the electric machines. We thought to study the control of a permanent magnet synchronous generator (PMSM) in the presence of such phenomenon
