STUDI RUGI DAYA SISTEM KELISTRIKAN BALI AKIBAT PERUBAHAN KAPASITAS PEMBANGKITAN DI PESANGGARAN

Abstract

In the years of 2014 until 2015 Pesangaran plant

capacity undergo changes due to the expiration of

employment contract lease diesel units and also the addition

of new plant unit of 200 MW PLTMG. An increase or

reduction in plant capacity of electrical system Bali will lead

to significant changes to the load flow, power losses and

energy losses in the circuit of Bali electrical Transmission

system. Load flow analysis and power losses in Bali

electricity system is simulated in five scenarios. Scenario 1 for

the conditions of existing in 2014, scenario 2 is currently

experiencing a reduction Pesanggaran plant capacity in

December 2014, scenario 3 is currently experiencing

Pesanggaran plant capacity additions in 2015 by using a peak

load of 2014, scenario 4 is the scenario 3 with using predicted

peak load in 2015, and scenario 5 is the scenario 4 with

assuming the Celukan Bawang plant operates at 130 MW.

Based on the results obtained by analysis, scenario 2 has the

most power and energy loss about 46.34 MW and 300.39

GWh. For the loss of power and energy Bali electrical systems

after Pesanggaran plants changes in 2015 are 38.57 MW and

250.05 GWh.
