Abstract

The distribution system of Aurora is operated and maintained by AURELCO. The cooperative maintains four feeders supplying the municipalities of the province. These feeders are Feeders 1 and 2 of the CENTRAL feeders, Feeder 3 the DINGALAN feeder, and FEEDER 4 of the DICADI feeder. The study focuses on the loading of the distribution transformers in the system. Data of the feeders coming from the cooperative was simulated on PowerSolv DSAS software. The simulation showed that 12 transformers from CENTRAL, one from DINGALAN, and four from DICADI have experienced overloading. From the result of the simulation, the monthly loading of the overloaded transformers were gathered to represent the actual loading experienced by the transformer. The actual cycle of the transformers were then transformed into a two-step load cycle using the method provided by IEEE. The resulting load cycle of the transformer were compared to what was the recommended loading for transformers by IEEE. As a result, the comparison showed that one transformer of CENTRAL and two transformers of DICADI have loading beyond the allowable loading. Because of this, alternative solutions to reducing the load on transformers whose loads exceeded the recommended limit was then developed and analyzed. Alternative solutions done in the study include load splitting and transformer replacement.
