Abstract
PLN Indonesia Power ULPL TA Musi utilizes the potential energy of
water which is then used to drive a turbine connected to a generator rotor.
Excitation system plays an important role in controlling the stabil of a
generator as a controller and functions to control generator output such as
voltage, current and power factor. The excitaton system for all units in the
Musi hydroelectric power house uses a brush excitation system. Brush
excitation is an excitation with a brush by utilizing the output of the generator
itself as the excitation. There are 3 types of generator power, namely active
power (MW), reactive power (MVAR), and apparent power (MVA). This data
is taken from the daily operaing data of the Musi turbine hydropower unit 1.
The highest power factor value is obtained in the early morning of 0,999 Cos
with a reactive power value of 0,5 MVAR to 1,8 MVAR. While the lowest
power factor value is 0,975 Cos with a reactive power value is 6,2 MVAR.
The smaller the reactive power value, the greater the power factor.
