Flexible, modular packages for every use case

PSS®CAPE offers a number of packages designed with your work requirements in mind. Any package can be enhanced with optional modules.

The foundation - every package starts with three basic elements

The unique built-in Database is one of the key advantages of PSS®CAPE, allowing customers to optimize data quality and reliability. The central database enables data to be automatically shared and used across all modules, eliminating the need for manual updates.

The Database Editor Module is the basis for all PSS®CAPE functions. With this module, protection engineers can simplify transformer model building, including; relay, recloser, and fuse model import; data merging, and quick entry of protection data.

The One-Line Diagram Module enables users to build and maintain a system one-line diagram and the display of data, short circuit results, and protection simulation responses. With this module, users get direct access for opening breakers and applying faults.

Pro-Standard Package

The most popular PSS®CAPE suite used by utility protection engineers including the Database, Database Editor, Short Circuit, One-line Diagram, Coordination Graphics, Line Constants, Relay Setting, System Simulator, Relay Checking and Order Production.

Pro-Ultimate Package

The most comprehensive suite of protection simulation tools utilized by the most advanced protection engineers encompassing Power Flow, Short Circuit Reduction, Breaker Duty, Settings Transfer capabilities plus all the features of PSS®CAPE Pro-Standard suite featuring the Database, Database Editor, Short Circuit, One-line Diagram, Coordination Graphics, Line Constants, Relay Setting, System Simulator, Relay Checking and Order Production.

Modules

The Short Circuit Module calculates any type of fault on any size system. Supports standard and customized reporting, automated fault studies, fault location analysis, and user-defined fault conditions.

The Coordination Graphics Module displays overcurrent and distance protective device characteristics. Supports interactive contingency and fault application, graphical relay resetting, and direct resetting of relay and distribution recloser taps and test points.

The Line Constants Module computes the self positive-sequence impedance and the self and mutual zero-sequence impedances of overhead transmission lines based on conductor and tower data. for building and maintaining a system one-line diagram and display of data, short circuit results, and protection simulation responses. Direct access for opening breakers and applying faults.

The Relay Setting Module represents a company’s relay setting procedures as user-written macros that perform fault studies, compute raw relay settings, and select actual taps. Library of "starter macros" includes setting digital distance relays in permissive overreach transfer trip schemes, plus many more.

The Relay Checking Module provides automated stepped-event simulation of your protection system in response to a variety of fault scenarios. This unique capability allows you to perform wide area evaluation of protection to uncover miscoordinations. Summary reports of one line per fault make it easy for you to spot trouble.

The System Simulator Module performs single-scenario studies interactively with the one-line diagram.

The Order Production Module generates data-driven reports on paper of relay settings based on taps and test points for specific locations.

The Power Flow Module offers both Newton and Fast Decoupled solution methods. Control algorithms support tap and phase-shifting transformers, voltage control by reactive generation, switched capacitor bank operation, and area interchange control.

The Short Circuit Reduction Module offers two types of network reduction; useful for providing reduced models for EMTP calculations, for other “non-PSS®CAPE” programs, and for sharing data with a utility's neighbors.

The Breaker Duty Module automates the evaluation of breaker interrupting duty following approved procedures of either the IEC or ANSI standards. Streamlines the evaluation of new and existing breakers.

The Settings Transfer Utilities Module can export settings for any group of relays to one or more Neutral Interface files; settings can be taken to the field and safely viewed and modified by the test engineer, reviewed, annotated, and saved.
