- Power system small signal stability is very important subject on studying of power system planning and power system operation. The study of this kind of stability is done continuously in order to avoid failure in the system. The aim of this research is to identify factors that influence stability of single machine connected to an infinite bus and how control system affect the stability. The generator model which is used on this research is Heffron-Phillips model. The stability is known by observing the eigenvalues of generator in a certain condition. According to the result of this research, it can be known that stability of generator is affected by generator loading, the reactance of transmission, and the tuning of control system such as AVR and PSS. Increasing of generator loading and transmission reactance will lead instability. However control system will improve stability if it’s tuned correctly. Incorrect tune of control system will not lead to stability improvement, moreover can lead instability. On heavy loading, the addition of high gain AVR is prohibited. However high gain AVR addition is allowed on low loading. The addition of PSS can be done either in high loading or low loading
