Power System Transient Stability Analysis - PSS/E and PSLF (Slides)

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.
