This seminar is one of the deliverables of a survey of the american Wide Area Measurement System (WAMS) projects. The survey has been performed by Olof Samuelsson during 1999. It is documented in the report Wide Area Measurements of Power System Dynamics - The North American WAMS Project and its Applicability to the Nordic Countries, which is included in the registration fee to the seminar. The seminar is organized by IEA, LTH, and is supported by ELFORSK and the Swedish Power Engineering Chapter of IEEE.

The day is dedicated to different aspects of WAMS and its relevance to the Nordic countries. Dr. John Hauer is one of the key persons in the WAMS effort and is the main speaker. Dr. Kjetil Uhlen will talk about the Nordic power system and Norwegian plans related to WAMS. Dr. Daniel Karlsson describes the work with a Swedish system for wide area protection against voltage collapse. Dr. Olof Samuelsson discusses university research and WAMS.
 
 

Background

After the repeated system disturbances in western North America during the 1990-ies, several activities have been launched to improve power system reliability. The federal utilities, National laboratories and universities have teamed in the Wide Area Measurement System R&D project. This effort focuses on managing system-wide power system dynamics. For this purpose, measurement systems for acquisition of dynamic data have been designed and deployed. The data has so far been used for disturbance analysis and calibration of dynamic system models. As the measurements system provide on-line data, current development deals with on-line operator support. The importance of managing knowledge critical for power system operation has also been identified. Software tools for extracting and archiving such information from measurements are also being studied. The WAMS effort is intended as a technology demonstration, but has now been established technology and serves as a foundation for further technical development.

Speakers

Dr. John Hauer is with Pacific Northwest National Laboratory in Richland, WA, USA, working with direct analysis and control of large power systems. He obtained his PhD degree in electrical engineering from University of Washington in 1968. At Bonneville Power Administration John Hauer was Principal Engineer for Power System Dynamics and one of the leading persons to initiate the WAMS project.

Dr. Kjetil Uhlen is employed as a Research Scientist at SINTEF Energy Research (formerly EFI) in Trondheim, Norway, since 1987. He obtained his PhD degree in control engineering from the Norwegian Institute of Technology in 1994. Main research interests are dynamic security assessment and control of power transmission systems.

Dr. Daniel Karlsson is with ABB Automation Products in Malmö, Sweden. He obtained a PhD degree in Electric Power Engineering from Chalmers Institute of Technology in Göteborg, Sweden, in 1992. Daniel Karlsson has performed research on dynamic load modelling and was involved in the development of the Swedish system for wide area protection against voltage collapse.

Dr. Olof Samuelsson is a postdoctoral fellow at Dept of Industrial Electrical Engineering and Automation, Lund Institute of Technology, where he obtained his PhD in 1997. Olof Samuelsson has recently spent six months at Powertech Labs,Canada, and six months at Techical University of Delft. His research interests are mainly in analysis and control of power system dynamics.
