Leading the market for highly detailed protection simulation, PSS®CAPE enables your protection engineers to be more effective and your power system to be more reliable.

Protection engineers face an ever-increasing landscape of challenges around power system protection. These challenges include the growth of digital technology, increased number of protection system data points (i.e. digital relays, substations, etc.) and pressure to maximize grid reliability. PSS®CAPE supports protection engineers from transmission utilities, large distribution utilities, and some generation owners with their entire workflow including detailed protection data collection, electronic setting management, setting calculations and validation.

With its extensive library of highly detailed relay models and selection of modular protection tools, engineers can seamlessly manage voluminous and complex network data, uncover potential problems, and examine alternative solutions.

Key Features and Highlights

Since the 1980's, PSS®CAPE has been optimized to meet the needs of real protection engineers. Driven by customers, we offer focused capabilities that enhance your everyday work.

• Leverage detailed modeling capabilities based on a single open source database.
• Complete analysis and simulation to solve data management issues, uncover potential network and protective device problems, and evaluate alternatives.
• Run simulations on networks of any size ranging from under 100 buses to 10,000 buses – including protection systems with 20,000 to 50,000 relays or more.
• Utilize capabilities for setting complex modern digital relays, relay coordination functions and automation of wide-area coordination studies.
• Ability to integrate with PSS®E transient stability to allow the kind of evaluation of wide-area control needed to avoid cascading outages and blackouts.

Largest Library of Highly Detailed Relay Models

Get access to the world's largest library of highly detailed relay models, with over 6,000 relay styles, reclosers, and fuses. Unlike generic placeholder models, the detailed relay models address internal and external supervision, phase and fault selection logic, CT and VT input expressions, and actual phase and ground-distance comparator equations. Detailed relay models respond accurately to setting changes. The experienced PSS®CAPE team will also provide customized support to help develop on-demand models.

Automated Wide Area Coordination Review

Leverage an innovative proven methodology to automate the wide area coordination review of your protective devices, this feature utilizes the existing network model as a basis to verify coordination among backup protection devices throughout a high-voltage transmission system. Almost any network data in electronic format, when updated and supplemented with protection data under this project, allows the automation of the entire coordination review and reporting process using the PSS®CAPE Compliance Module.

Interfaces with Relay Manufacturers' Setting Software

Reduce time and errors through automatic import of relay settings files. Some relays, such as those from Siemens allow PSS®CAPE to update the settings file as well as reading the file. Interfaces for this program are available for over 13 relay manufacturers.
