   Design and Performance of a Superconducting Energy Management System (SEMS) for Industrial Power Quality Applications
By H-Christian Doht; M. Hilscher; K. Prescher; F.-J. Unterlass [View]
[Download]

Abstract: Superconducting Magnetic Energy Storage (SMES) attached to a STATCOM (Static Synchronous Compensator) offers a system beyond the classical solutions provided by capacitor banks, capacitive filters, Static Var Compensators (SVC), to meet the stringent power quality requirements of large, highly sensitive industrial facilities. The system, names "Superconducting Energy Management System" (SEMS) is a further development of SMES technology. It constitutes a plant wide "at the fence" protection system that mitigates all incoming voltage sags and power interruptions for facilities in the tens - of - megawatt range. This paper presents information on Industrial Power Quality (IPQ) requirements, a description of a SEMS design, a digital simulation and analysis of SEMS behaviour to provide a cost effective and technically sound solution.

   Testing of Grid-connected Converters Against Power System Faults
By M. Bollen; J. Svensson; L. D. Zhang [View]
[Download]

Abstract: The various characteristics are described of voltage dips due to short-circuit faults in the electric power system. These voltage dips are notorious for their adverse effect on the operation of singlephase and three-phase power-electronic converters. Based on a classification of three-phase unbalanced dips, a testing protocol is proposed. The testing protocol may be applied to, among others, existing equipment, prototypes of new equipment, and control algorithms in an early development stage.

   Transient performance and design issues for a parallel-connected voltage sag and outage compensator
By L. Voss; A. Steimel; R. Lürick [View]
[Download]

Abstract: A compensator is presented for mitigation of voltage sags and outages in industrial power systems. The system is based on a commercial Power Conditioner and is appropriate for load ratings from 100 kVA up to several MVA. Transient performance is investigated by simulation and with a 10 kVA lab prototype. Design issues and a discussion of the required fault detection scheme are presented.
