| Abstract | ||||
| This paper presents a magnetic voltage regulator (MVR) as a new technique for sensitive voltage control of three phase self-excited synchronous generator. The proposed MVR is a passive magnetic element, consisting of a magnelic core with three limbs Three identical main coils (MC) are mounted on the middle limb and they are connected in series with the generator Iipes, with special arrangements. The second limb carries a regulating coil (RC), which is connected to a variable inductive reactance for orienting the flux into the core limbs. An exciting coil (EC) is mounted on the third limb. which feeds the generator field winding &rough a bridge rectifier. The MVR 'offers a versatile range of regulating characteristics. It has small size, simple and. reliable &d exhibit low impedance and low energy loss. The equivalent circuit model representing the system is proposed. Equations describing the system are developed and computed, illustrating the theoretical performance. The experimental set up is implemented to obtain the measured results at no-load and load operation. Calculated and measured results at different values of load are presented, where good. agreement has been achieved. | ||||
