This paper is proposed a generalized proportional integrator (GPI) controller for static synchronous compensator (STATCOM) based on instantaneously reactive power (IRP) theory. For this purpose, at first the reference current of each phase is calculated using the related equation and then the switching signals are generated based on GPI controller. Designing of controller parameters is done based on system transfer function and gain margin in the frequency domain. Also, this paper is proposed the selecting of GPI coefficient to compensate the output current sensors delay and steady state gain variation. In the other parts of this paper, a STATCOM is designed and is simulated based on proposed controller. In these simulations, the capability of STATCOM is studied in different conditions such as inductive and capacitive load. Furthermore, the effect of load variation is investigated and the controller capability is evaluated. Finally, a 10KVA laboratory prototype was designed and fabricated and real test results was compared with simulation results.
