Indonesia Power PLTU Suralaya}, year={2019}, url={http://156.67.221.169/1626/}, abstract={The power plant has several main components, one of which is a generator which becomes a vital equipment in a power plant. In a generator with a large capacity performance, it is desirable to be in good condition to supply large-scale electric power in an interconnection system. The generator is closely related to the excitation system as well as the excitation current, the excitation current can affect the value of the reactive power produced by the generator, power factor, and terminal generator voltage. Therefore it is necessary to do an analysis on this matter to find out how the performance of the generator unit 7 of the Suralaya PLTU. After analyzing this generator the performance is good, with excitation current values ranging from 2596 A - 3689 A, reactive power values ranging from 27 MVAR - 248 MVAR, stable power factor values ranging from 0.9 - 1, and terminal generator voltage stable stability ranges from 22.5 KV - 23.98 KV according to the limits of the capability curve and operating recommendations} }
