| dc.description.abstract | The transformer provides an additional facility in the form of an on load tap
changing transformer which can be used for voltage stability as well as repairing
and regulating the power flow and voltage profile of a distribution network system.
The position of the transformer tap can also change the impedance of the
transformer so that it will affect the flow of power in the system. Changing the
transformer tap changer will directly change the voltage profile of the bus
associated with the transformer tap. The influence of the transformer tap will also
affect the flow of system power and the amount of power supplied to the system.
Changes in the voltage and power flow of this system will also change the amount
of current flowing between these buses and will also affect other buses and affect
system power losses. In this thesis, setting the tap changer value of the transformer
is carried out on the PT.INALUM (persero) Kuala Tanjung network system, where
the transformer in that company has the tap changer value already tapped, therefore
an evaluation is carried out for each tap changer value on the transformer that has
been tapped in that company using the Artificial Bee Colony (ABC) Algorithm to
obtain the value of the newly reviewed transformer tap changer from minimum
power losses. System power flow studies were carried out on changes in the value
of the transformer tap changer after being evaluated and the values of power losses,
total power supplied to the system, current and voltage profile were obtained. By
comparing the results of the power flow study before and after the evaluation, it
was found that the power losses decreased from 1666.1 kW and 56741.9 kvar before
the evaluation decreased to 1586 kW and 54042.6 kvar after the evaluation, the
system power losses decreased of 80.1 kW or 4.8% for active power losses and
2699.3 kvar or 4.75% for reactive power losses. | en_US |
