This study starts from the proof of Low Frequency Oscillation (LFO) and then points out that there
are many ways to study the LFO including its rejection measures. Also in this study one control system is
planned in order to regulate voltage at common coupling point (PCC) in where STATCOM is installed. This
research present a single-machine infinite-bus system with one static synchronous compensator (STATCOM)
asymmetrically installed as a current source. Together with a classical generator model, the simplest power
equation is obtained to give direct and clear physical concepts on synchronizing and damping torque factors.
According to the primary equations, some basic issues, such as the relationship of voltage gain control and
damping control, operating conditions, and the installation of STATCOM, are investigated in this research.
Then, with assistance of proportional controller for voltage regulation and damp control, the digital simulation
indicate the necessity of control of STATCOM in damping power system oscillations and supplying regulated
voltage support.
