Abstract
Generator is a machine of generating electrical power by converting mechanical energy into electrical energy. In the generator, the mechanical energy obtained from the prime movers can include diesel engines and turbines. In large plants, the conversion tool that is often used is 3-phase synchronous generator. Synchronous generator is a synchronous generator that reviewed 11 KV, relationship (star) Y on Keramasan power plant Unit 3. Operation of the generator needed a generator of stability in order to become optimal performance. The stability of the generator can be affected by several things, namely the burden, excitation current, power factor, the round number generator, and so forth. Active power load changes due to large voltage terminal connected to the load will cause instability generator. The purpose of this study is to look at the characteristics of the three-phase synchronous generator of load to power the load current changes. From the results of the evaluation of the value of the electromotive force of the armature, the armature current, current amplifier, and efficiency will go up as you load active power. Where the value of the armature electromotive force (Ea / ph) is obtained when the load active power of 14.5 MW of power factor 1 is 6273 V, the electromotive force of the armature (Ea/ph) on the lagging power factor is 6287 V, the value of force electrical armature (Ea/ph) on the leading power factor is 6231 V, the armature current 790 A, and 17 A current excitation, and the efficiency is 98.46%.
