PSS™E package is comprised of a comprehensive suite of programs for studies of power system transmission network and generation performance in both steady-state and dynamic conditions. At present two primary simulators, one for steady-state analysis and one for dynamic simulation, facilitate calculations for a variety of analyses, including:
Power flow and related network functions
Optimal power flow
Balanced and unbalanced faults
Network equivalent construction
Dynamic simulation
Through the PSS™E interface the following functions and analyses are available:
Power flow and related network functions
Optimal power flow
Open access
Fault analysis
Network equivalencing
Dynamic simulation
One-line diagrams
Program automation
Additionally, one of the most basic premises of PSS™E is that the engineer can derive the greatest benefit from computational tools by retaining intimate control over their application. PSS™E users accustomed to such control by use of the IPLAN program language now have available the additional capability to run Python programs within PSS™E for batch control and automation of the simulation processes.
The PSS™E interface supports a variety of interactive facilities including:
Introduction, modification and deletion of network data using a spreadsheet.
Creation of networks and one-line diagrams.
Steady-state analyses (load flow, fault analysis, optimal power flow, etc.).
Presentation of steady-state analysis results.
Dynamic simulations (transient, dynamic and long term stability analysis).
Presentation of Dynamic simulation results.
