Abstract: This paper deals with the performance analysis of static compensator (STATCOM) based voltage regulator for self-excited induction generators (SEIGs) supplying non-linear loads. In practice, a number of loads are non-linear in nature and therefore they inject harmonics in the generating systems. The SEIG being a weak isolated system, its performance is very much affected by these harmonics. The additional drawbacks of SEIG are poor voltage regulation and it requires adjustable reactive power source with varying load to maintain constant terminal voltage. A three-phase insulated gate bipolar transistor (IGBT) based current controlled voltage source inverter known as STATCOM is used for harmonic elimination and it provides required reactive power for the SEIG with varying loads to maintain constant terminal voltage. A dynamic model of the SEIG-STATCOM feeding non-linear loads using stationary d-q axes reference frame is developed for predicting the behavior of the system under transient conditions. The simulated results show that SEIG terminal voltage is maintained constant even with non-linear balanced and unbalanced loads and free from harmonics using STATCOM based voltage regulator.
