Topic: Power System Transient Stability Analysis – PSS/E and PSLF
Presented by: John Undrill, PhD, Arizona State University
This webinar:
Sixty years of computer development have allowed the capacity of power system dynamic simulation programs to advance from a few dozen buses to several tens of thousands. More importantly, advances in testing of power plant and load equipment have established strong understanding of where simulations are a reliable indicator of expected behavior, and where they must (still) be used with care. The management of data for large scale simulations continues to be of concern. While confidence in simulations of ‘conventional’ switch-connected equipment is well supported by observed system behavior, simulations of electronically connected load and generation must still be examined closely. It is clear that the capabilities of fundamental frequency simulations and of electromagnetic transient simulations will merge as computing capability continues to advance. It is also clear that the assembly and maintenance of simulation data bases will be a persistent and significant challenge.

John Undrill has worked on the dynamics of electric power systems with General Electric, Power Technologies Incorporated, and Electric Power Consultants Incorporated. In recent years he has been a Research Professor at Arizona State University. His work has included both the development of dynamic simulation programs and testing to support dynamic modeling; it has involved power transmission, hydro electric power plants, and large gas turbines. Undrill was responsible for the initial development of the PSS/2 and PSS/E programs at PTI, and for the PSLF program at EPCI. John Undrill received BE and PhD degrees from the University of Canterbury. (New Zealand) He is a Fellow of the IEEE and a member of the National Academy of Engineering. He is a Life Member of the IEEE.
