Ann Arbor, Michigan – March 15, 2016 – Electrocon International, the full-service developer and marketer of CAPE software for protection system simulation and data management, has announced support for PRC-027 is now available within its latest software version CAPE 14. The feature that supports fault level comparisons was released to selected companies last June and is now available to all CAPE 14 users.
"Support for PRC-027 and other industry regulatory standards is what CAPE has been about since its inception thirty years ago," remarked Paul F. McGuire, EE, MSEE, PE and President of Electrocon International. "CAPE 14, addresses many of the top issues facing protection engineers today, including the need to conduct numerous studies to meet NERC regulatory requirements such as PRC-027, which has recently received committee approval. Utilities need tools that automate the generation of report data and CAPE provides the ability to significantly reduce the amount of manual effort required to create the information for these reports."
CAPE offers extensive tools for detailed relay modeling that help engineers manage voluminous and complex network data, uncover potential problems, and examine alternative solutions. Supporting the system protection function within electric power utilities, CAPE is used by transmission, distribution and generation companies as well as electrical engineering firms in more than 50 countries on six continents worldwide.
PRC-027 is a standard "to maintain the coordination of protection systems installed for the purpose of detecting faults on BES elements and isolating those faulted elements, such that the protection systems operate in the intended sequence during faults."
To support PRC-027, Electrocon developed new features for creating and comparing entire-system fault levels along with methods for exporting settings.
CAPE’s System Simulator and Relay Checking modules provide for "quality reviews". The "Wide-Area Coordination Review" concept, i.e. system simulations managed by customized macros, was first conducted on a large scale review in 2006 by a CAPE utility user in Spain. Since that time, other utilities and consulting firms have continued to develop and refine the assessment method. CAPE’s automated relay setting macro, first developed in 2001, has been utilized by many utilities and is currently being implemented by one European utility as part of a multi-million Euro project to fully integrate grid management including short- and long-term planning as well as maintenance.
"Providing continuous improvements, based on input from CAPE users and meeting the latest industry standards and regulatory requirements, along with our responsive customer support, has been key to Electrocon’s success and the reason why we have customers who have worked with us for 5-, 10-, 15- 20- and even 30-years," commented McGuire.
In addition to PRC-027, CAPE 14 provides support for NERC standards PRC-019-1 (coordination of Generator Voltage Regulator Controls with Unit Capabilities and Protection), PRC-023-2 (Transmission Relay Loadability), PRC-025-1 (Generator Relay Loadability), and PRC-026-1 (Stable power Swing Relay Loadability).
CAPE 14 includes a number of new features designed to enhance usability and improve engineering productivity, including:
• Automated time-distance diagrams with an option to store in database.
• Edit forms for adjusting existing double/triple/quadruple, ring, and breaker-and-a-half detailed bus structures.

CAPE Third-Party Interface Modules
CAPE offers optional connectivity with third-party software applications commonly used for planning and asset management. Two such modules include CAPE-TS Link and the IPS-CAPE Bridge™. In addition, the CAPE Neutral Interface (CAPE-NI) allows CAPE to share relay data with other asset management software.
Bridging the gap between Planning and Protection
A new optional module in CAPE 14 is the CAPE TS-Link module which integrates the detailed protection system model of CAPE with the time-domain model of the Siemens PTI PSS®E transient stability simulation. CAPE-TS Link was designed to aid in conducting compliance studies for the NERC PRC-026-1 standard for “Relay Performance During Stable Power Swings”. This unique simulation tool combines Electrocon’s premier stepped-event protection system simulation with time-domain transient stability programs. It enables for the first time a reliable simulation of the bulk electric power system in a way that models the effect of protective relay operations on the dynamic behavior of the system. The ability of the installed or planned protective devices to meet the critical clearing time criteria can now be demonstrated. CAPE’s library of detailed distance, overcurrent, voltage, and differential protective devices has been augmented with frequency and out-of-step relays to support unexcelled realism.
CAPE-TS Link is an option for CAPE 14 users with Siemens PTI PSS®E. Special introductory pricing is being offered to CAPE customers adding this module as a part of their upgrade to CAPE 14.
Protection System Data Management Connectivity
The IPS-CAPE Bridge provides two-way data exchange between the IPS-RELEX™ asset data management software and the CAPE protection system simulation environment. The Bridge manages the mapping of data common to both products in a way that preserves data integrity. Depending on the transfer the user requests, it can create new substations, LZOPs, relays, and relay settings in the destination database or simply update them if they already exist.
CAPE software is built for engineers responsible for protection of high voltage transmission systems and distribution systems within electric power utilities and includes:
• Detailed modeling capabilities based on a single open source database.
• Support for analysis and simulation to solve data management issues, uncover potential network and protective device problems, and evaluate alternatives.
• Support for networks of any size.
• Support for setting complex modern digital relays.
• Support for relay coordination functions and wide-area studies.
• Ability to integrate with conventional transient stability programs to allow the kind of evaluation of wide-area control needed to avoid cascading outages and blackouts.
CAPE handles networks of any size, large or small. CAPE users have systems ranging from under 100 buses to over 30,000 buses. Several have protection systems with 20,000 to 50,000 relays.
Simulating short circuits and showing the responses of protective devices
With CAPE, you use a mouse to click and drag elements on a one-line diagram, and to open breakers, apply faults, and simulate protective system responses. Conducting automated fault studies and wide area coordination reviews, developing incisive custom reports, and identifying fault locations, all become practical, efficient activities that add value to the organization.
More detail gives you more realistic results
CAPE’s ability to handle rich detail allows users to create models accurate enough to realistically predict likely misoperations. CAPE handles model-specific comparator equations, phase and fault selection logic, manufacturer- and model-specific setting names, and internal supervision logic. CAPE comes with a library of relays, distribution reclosers, and fuses, all ready to use out of the box.
Get the most from your data
CAPE is built upon a true relational database, which is included with CAPE software. CAPE’s underlying DBMS is fully ODBC- and SQL-compliant; therefore, the CAPE database may be accessed by programs like Oracle and Microsoft Access. All of the CAPE modules use the same CAPE database, so any data item is entered once and may be used many times.
CAPE Software Maintenance Agreement
CAPE users with an active software maintenance agreement receive unlimited technical support from Electrocon engineers by phone and email. Unlimited technical support includes help with writing SQL code for interrogating the database and general technical support issues related to protection. Software “updates on demand” for active maintenance agreement accounts, allow users to quickly and easily receive software updates, incremental functionality improvements, and newly-developed relay models.
