Voltage sags are very frequent events associated with faults in the network, with energization of transformers or starting of large motors. Although their duration is very short, they can represent a big problem for industrial plants, especially for those characterized by the presence of sensitive loads, like power electronics devices. In this pa per, the problem of the design of a device able to compensate voltage sags, namely a Static Series Compensator (SSC), is thoroughly analyzed, both from the point of view of the choice of the components and their rating and from the stand-point of the control system. The model has been implemented with the aid of the electromagnetic code PSCAD-EMTDC and has been tested in a radial distribution network for the protection of a nonlinear load consisting of a diode rectifier. © 2005 IEEE.
