【 摘 要 】

The electricity in Bagan Siapiapi is distributed 20 kV feeder distribution system. The main supply of Bagan Siapi-api from the Diesel Power Plant which is located ± 1.5 kms from the load center and the main substation of Duri is ± 102 kms from Bagan Siapi-api city through the Substation circuit Ujung Tanjung. The long distances between the Duri Mainstation and Bagan Siapi-api city resulted in a 14.85 kV end-voltage and a power loss of 988.7 kW. Voltage loss results in a lack of optimum service to the consumer and a large loss of network power become uneconomical for power supply operation. The result of end voltage calculation is 11,542 kV, and the power loss is 988.7 kW. After the main relay station in the village of Pedamaran operates, reconfiguration-1 produces the lowest end voltage calculation of 16.21 kV and a power loss of 136.59 kW, while reconfiguration-2 produces a low-end stress calculation of 17.37 kV and a power loss of 56.93 kW.
