Abstract: A novel approach to reduce the current magnitude during feeder load transferring is presented in this paper. No matter in planning, designing, or system dispatching, it is desired to give un-interrupted electric power to customers. However, when the loading of a distribution system power feeder is too high or the feeder needs to be maintained, the feeder load should be transferred to other feeder. The un-interrupted type means that the electric power supplied to customers will not be interrupted during feeder load transferring. However, there are several factors to affect the feeder current magnitude during load transferring, such as transformer impedances, primary side power level, and original loading of the feeder. If the current is too high, the feeder protection system will trip the feeder breakers to shut down the power supply system. A novel approach is presented to reduce the feeder current magnitude during load transferring. The phasor measurement units (P!
MU) will be used to obtain the synchronous voltage magnitude and phase angle of the transformers, of which feeders are transferred. A power conditioner is installed in the secondary side of the transformer. Then the phase angle values from the PMUs will be sent to the power conditioner and the suitable phase shifting will be used to reduce the phase angle difference between the two transformers. The simulation results show the feeder current magnitude will be greatly reduced during load transferring.
