STEADY-STATE ANALYSIS OF 3-PHASE SELF-EXCITED RELUCTANCE GENERATORS

A three-phase reluctance machine can be made to operate as a self-excited generator when its rotor is driven at suitable speed by an external prime mover and its excitation is provided by a capacitor bank connected to the stator terminals. The reluctance generator has almost all the advantages of its counterpart induction generator and has in addition the advantages of constant frequency operation and bow core and copper losses. This paper introduces an analysis of the three-phase self-excited reluctance generator The developed analysis avoids the limitations of the previous works whereby the effect of the core loss is soundly taken into consideration. The analysis is suitable for variable speed, load and excitation capacitance operations. The validity of the proposed analysis is confirmed experimentally The effect of neglecting the core loss is also studied.
