Analisis Pengaruh Perubahan Tegangan Eksitasi Dalam Mengoptimalkan Tegangan Keluaran Generator Sinkron Akibat Perubahan Beban

With the increasing importance of the role of electric power in everyday life, especially for industrial purposes, the quality of electric power is also becoming an increasingly large demand from electricity users. The quality of this electric power includes, continuity of supply, voltage value, frequency value, voltage flicker, or harmonic. The performance of synchronous generators is very important because it directly affects the stability and reliability of the electrical system as a whole. One of the factors that cause generator voltage instability is the load impedance value. The load impedance is described in the form of a complex number (RL+jXL) consisting of a resistive value (RL) and a load reactive value (XL). In this study, an analysis will be carried out to determine the effect of changes in resistive and reactive loads on the generator terminal voltage and see how the characteristics are. Based on the loading history of a 3.3 kV synchronous generator with a capacity of 3,125 kVA for 10 days, then load impedance samples were taken and scenarios of changes in resistive or reactive loads were carried out and recalculations were carried out to determine the value of current, terminal voltage, and load power. By increasing the resistive load only (+5% from the previous condition) while the reactive load is constant, it will cause the terminal voltage to increase, the current will decrease due to increased load impedance, and the active power and reactive power also decrease. Meanwhile, when the resistive load is constant and the reactive load increases, it can cause a decrease in terminal voltage, a decrease in armature current, active power also decreases but reactive power increases. This proves changes in load impedance and power factor cause voltage instability of generator terminals, and it is important to understand the causation of these events in order to provide proper handling.
