With the addition of integrated node-breaker support in version 34, PSS®E is leading the market in advances in electric transmission modeling and simulation.
See the Details Tab for more information on value-add modules.
The PSS®E base package includes:
Fast and robust power flow solution for network models up to 200,000 buses
Lightning-fast steady-state contingency analysis, including automatic corrective actions and remedial action scheme modeling
Full node-breaker support for detailed modeling of substation topology

Additional Value-add ModulesThe PSS®E base package can be enhanced to include one or all of the following modules:
Results analysis and visualization module (RAV)
Geomagnetic Induced Currents (GIC)
Graphical Model Builder (GMB)
Eigenvalue and Modal Analysis (NEVA)
Optimal Power Flow (OPF)
Short Circuit Calculations
Introduced in PSS®E Version 33.5 as a value-added module, Results Analysis and Visualization (RAV) brings ease in results analysis and new ways of interacting with your output data.
Dynamic Simulation The PSS®E Dynamic Simulation module is a versatile tool to investigate system response to disturbances that cause large and sudden changes in the power system. The dynamic simulation module employs a vast library of built-in models for modeling different types of equipment, and with capability to create user defined models of any complexity. An integrated dynamic simulation plotting package allows for quick generation of plotting with ability to export to several popular graphic formats.
Geomagnetic Induced Currents (GIC) Power system planners and operators require technical tools to conduct studies to assess the impact of GIC currents in the power grid and prepare mitigation measures. The value added GIC module for PSS®E meets their requirement using the latest method of calculation recommended by NERC. The method used is the induced voltages in transmission lines from the voltage sources.
Graphical Model Builder (GMB) Graphical Model Builder (GMB) module is a powerful and easy to use dynamics model development tool based on graphic representation of control block diagrams. Accurate power system planning requires that precise models be used in the simulation software. PSS®E software is designed for dynamic modeling of complex systems. GMB allows specialized modeling by supporting both standard and non-standard dynamic models.
Eigenvalue and Modal Analysis (NEVA) Stability problems, such as inter-area oscillations, have become increasingly common in large interconnected power systems. The Eigenvalue and Modal Analysis (NEVA) module provides an extension of analytical methods to examine these oscillations. Used with the PSS® Product Suite, the NEVA module provides methods to investigate long-term stability, allows a deeper view into eigenvectors, determines the best damping locations, and allows evaluation of damping strategies.
Optimal Power Flow (OPF)
The Optimal Power Flow (OPF) module goes beyond traditional load flow analysis to provide the ability to fully optimize and refine your transmission systems. OPF improves the efficiency of power system performance studies by adding intelligence to the load flow solution process. Whereas the conventional load flow relies on the engineer to systematically investigate a variety of solutions before arriving at a satisfactory or good solution, OPF automatically adjusts controls to determine the best solution.
Short Circuit Calculations PSS®E Short Circuit module has a number of short circuit calculation algorithms to meet the diverse needs of fault analyses. All algorithms are self-contained analyses in PSS®E. They require a valid power flow working case and the power system sequence data.

The ability to manage and analyze detailed substation topology provides planners with even more powerful and accurate study capabilities.
With PSS®E 34 node-breaker it is possible to:
Auto-generate substation layouts to easily create complex topologies, including the ability to graphically manipulate details and fine tune the design
Simulate complex contingencies at the breaker level to accurately portray protection behavior
Readily compare planning and operation models at the substation level, which can aid in power flow base case validation and NERC MOD 33 compliance
Visualize substation topology at the device level with PSS®E single-line diagrams, allowing you to view power flow results at individual buses, breakers, and switches.
The best part is that the node-breaker tools in PSS®E 34 come with no additional cost!
