Abstract
This paper deals with a 3-phase voltage disturbance generator. The proposed generator can be used for the performance teat of custom power devices with nonlinear load characteristics as well as linear load. The principle of the voltage sag, swell, outage, and unbalance generation is described. The switching pattern for the SCR thyristors in each mode is analysed to guarantee the system reliability. The validity of the proposed scheme is verified through simulation result.
