Cost-Effective Power Quality Improvement for Industrial Plant
Paper i proceeding, 2003

Disturbances in the voltage supply, especially voltage dips and short interruptions, can cause tripping of sensitive electronic equipment and cause production stops in many industries. This paper proposes a power-electronics based device, obtained by a combination of a Static Transfer Switch (STS) in series with a Static Series Compensator (SSC) for protection of large industrial distribution systems against voltage dips and short interruptions in a cost-effective way. The hybrid compensator is modeled and simulated with different types of dips using the simulation tool PSCAD/EMTDC. Design of the device and control strategies are discussed. An economic evaluation of the device is carried out.
