| Abstract |
In the paper the analysis of the correlation of
dynamical with steady state properties of the converter fed
drives is presented. The analysis, based on the equations of
the system, is made for the self commutated synchronous
motor (SCSM), called also as the load commutated inverter
fed synchronous motor (LCI-SM). First, the requirements of
suitable acceleration of the drive and ratio of current
increase during the dynamical state are transposed to the
adequate commutation and control reserves of the
converters. Then the influence of the reserves, kept in the
steady state, on torque versus current characteristic,
maximum available torque (overload capacity), selection of
current limitation, power factor, loss and efficiency of the
drive is analyzed. The obtained dependencies are illustrated
in figures and with use of a number data. In the paper the
deterioration of the steady state properties with increase of
dynamics of the drive is concluded. |
