PSS™E from Siemens Power Transmission &Distribution,Inc., Power Technologies International (Siemens PTI), aworld leader in power systems analysis, provides userswith power flow, short circuit, dynamic simulation(including long term), optimal power flow, linearnetwork, and small signal analysis. The program employs the latest computer technology and numericalalgorithms to efficiently solve networks large and small.PSS™E includes modeling for advanced technologies,such as the application of FACTS devices and VoltageSource Converter HVDC Light systems. The programallows for a variety of analyses. When many cases mustbe analyzed quickly, DC load flow capability is provided.Dynamic modeling for PSS™E includes highly detailedgovernor models, allowing most standard boiler control strategies and very detailed HVDC models, which apply to specific installations.
