Abstract

In this paper a novel 3-phase voltage disturbance generator is described. Voltage sag, swell, outage, and unbalance can be provided by the proposed scheme. The main devices of the generator are SCR thyristors, sliding type autotransformers, and transformers, which makes the generator have good features of high reliability, high efficiency, and cost - effective system. Thus the generator can be used for the performance test of the custom power devices including UPS. The operating principle and the characteristics of the proposed scheme are analyzed and the simulation results show the usefulness of the generator.
