Abstract:
A method for providing series compensation of a rotating electric alternating current machine connected to a three-phase network for at least one of distribution and transmission, the three-phase network having a fundamental frequency, the rotating electric alternating current machine being one of directly connected to the three-phase network and connected via a static current converter, a stator winding of the rotating electric alternating current machine having three phases Y-connected, comprising the steps of:connecting a down side of a first phase of the three phases of the stator winding to a first side of a first capacitive circuit; connecting a second side of the first capacitive circuit to a ground of the three-phase network completing a first series capacitive circuit; connecting a down side of a second phase of the three phases of the stator winding to a first side of a second capacitive circuit; connecting a second side of the second capacitive circuit to the ground of the three-phase network completing a second series capacitive circuit; connecting a down side of a third phase of the three phases of the stator winding to a first side of a third capacitive circuit; connecting a second side of the third capacitive circuit to the ground of the three-phase network completing a third series capacitive circuit; and lowering a reactance of a system including the rotating electric alternating current machine by compensating the three phases of the stator winding through respective series capacitive circuits.
