abstract: Electrical energy is one energy that cannot be separated from human life today, 
hence it is important to have good quality electricity supply starting from its 
generation. The auxiliary system is a system in a power plant that functions to 
generate electricity, part of the electricity generated is not sold, but is used by the 
plant itself for generating electricity, in contrast to consumer loads that are sent to 
the transmission line. The auxiliary system is susceptible to disturbances that can 
hinder the electricity production process, ETAP or Electrical Transient Analyzer is 
a software that able to do load flow analysis, load flow analysis is a procedure used 
in the power system model under certain conditions to calculate important 
parameters to analyze the operation of a system. The auxiliary system of unit 1 UBP 
Suralaya consists of several equipment such as a 400MW generator that functions 
to provide a source to the system, two transformers, namely the Unit Service 
Transformer that functions to reduce the voltage nominal from the generator to the 
load busbar, the Station Service Transformer that functions to provide the initial 
source. One endeavor to increase the reliability of the electric power system is to 
apply a bus coupler that connects to another generation unit. This study concluded 
that the auxiliary system of unit 1 UBP Suralaya experienced disruption in its 
operation, namely overload on the transformer used, UST or SST, therefore that it 
is necessary to do uprating or increase specifications. And the use of bus coupler is 
considered impossible before the transformer and circuit breaker are uprated.
