Abstract :
The last of these duty discuss the effect of the excitation current against reactive power in PT. Indonesia Power UPJP Kamojang. The focus is the current study fluctuations excitation and the reactive power as well as the relations between them. The goal is to find fluctuations the current excitation and the reactive power and the effect of the current excitation against the reactive power. The current excitation directly proportional to the reactive power. In fact, the current excitation and the reactive power not always directly proportional. This study concluded that the bigger IF so Ea is large. At the phase R in a position IF = 418,6 A which was previously IF = 405,1 A worth Ea = 12,2777 kV formerly Ea = 12,2637 kV surge IF of 3.23 % of the current excitation formerly and there was a change in IF of ±7,43 A. The value VT tending to constant because keep synchronization with the system , Is as much as 11,814 kV be 11,8216 kV. Surge voltage 0,064 % of voltage formerly and there was a change in VT of ±0,00768 kV. The increase in Ea of ±0,0096 kV , the increase in Ea cause increase of 0,64 % of voltage network before. Fluctuations Q resulting from a change if range 6,128 % with change Q of ±0,501 MVAR. The linear value current excitation to power reactive 70,59 %. Besides part in phase R , the phase S and the phase T may have condition fluctuations that similar to the phase R .
