   A NEW CONTROL STRATEGY FOR A UNIFIED POWER FLOW CONTROLLER
By Q. Yu; S. D. Round; L. E. Norum; T. M. Undeland [View]
[Download]

Abstract: Real and reactive power flow in a transmission line can be regulated by a Unified Power Flow Controller (UPFC). In this paper a UPFC system is modelled, a new control strategy based on the synchronous rotating reference frame is proposed and the simulation and experimental results for the series converter of the UPFC are presented. When compared with previously reported control methods, the new control strategy has an improved dynamic response.

   DEVELOPMENT OF A FACTS FRONT END FOR EMTP
By N. H. Ramage; J. M. van Coller; R. Koch [View]
[Download]

Abstract: This paper discusses the development of a Microsoft Windows based preprocessor for EMTP which will facilitate experimentation with FACTS devices. The paper discusses the philosophy followed in the design of the front end and covers the issues of Software Quality and Maintenance and their implications. Included is an ·overview of the functionality of the preprocessor. The paper concludes with a short description of the implementation of FACTS devices within the program.

   THYRISTOR-CONTROLLED REACTOR ENHANCES SERIES CAPACITOR APPLICATIONS
By K. Renz; G. Thumm; St. Weiss [View]
[Download]

Abstract: Environmental considerations make it increasingly difficult to plan and erect new transmission lines and power generation plants. FACTS (Flexible AC Transmission Systems) provides devices for enhanced use of AC transmission networks., The Static VAr Compensator (SVC) has become a well proven technique, more than 100 units are operating in transmission systems worldwide. The combination of conventional series capacitor and thyristor-controlled reactors - an element well-known from SVC applications - was introduced into a transmission system in 1992. This first three-phase installation of Advanced Series Compensation (ASC) demonstrates that new FACTS devices using HVDC and SVC thyristor valve technology can be designed and operated successfully. It is expected that an increased number of FACTS equipment will be installed to solve some of today's and tomorrow's problems in AC systems.
