WRENDA WIRA PRADANA. ABSTRAK. PLTU PT Sinergy Power Source is one of the private PLTU that has capacity of 30 MW and supply 3 main expenses namely PT Mekabox, PT Sopanusa, and PT
Sunpaper. Currently the total load that must be fulfilled by PLTU PT SPS for the
three factories is 25.33 MW and will continue to grow because of the increase in the
production number of each plant. With the increasing amount of production, the
amount of load will increase so that additional generator capacity is required. This
research aims to determine the analysis of power flow planning and coordination
setting system protection against the addition of 30 MW generator capacity. Analyze
the power flow done using ETAP software with the Adaptive Newton-Rapshon
method. From the results of the study showed that after the 30 MW generator was
added, the work percentage of generators 1 and 2 was lighter and the value of the
power flow is relatively the same if the load value is unchanged. For coordination of
protection systems itself has been running correctly on handle disruption.
