Electrocon International to Demonstrate NERC PRC Standards Reporting Support in CAPE Computer-Aided Protection Engineering Software at the Western Protective Relay Conference

Leading computer-aided protection engineering software for high voltage electrical transmission and distribution lines Support for PRC-001, PRC-002-2, PRC-019-1, PRC-023-2, PRC-024-2, PRC-025-1, PRC-026-1 and PRC-027-1

6000+ detailed relay styles, reclosers and fuses

CAPE-TS Link option integrates with Siemens PTI PSSE transient stability simulation

IPS-CAPE Bridge option integrates with IPS Energy RELEX protection system data management software

Ann Arbor, Michigan – October 12, 2017 – Electrocon International, the full-service developer and marketer of CAPE software for protection system simulation and data management, will demonstrate the latest CAPE enhancements supporting NERC PRC standards and wide-area coordination studies at the Western Protective Relay Conference, October 17-19, 2017 at the Spokane Convention Center. 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. CAPE offers extensive tools for detailed relay modeling that help engineers manage voluminous and complex network data, uncover potential problems, and examine alternative solutions.

CAPE users expressed a need for tools to conduct NERC PRC compliance studies and to generate reports needed to meet these regulatory mandates, remarked Paul F. McGuire, EE, MSEE and President of Electrocon International. CAPE currently supports PRC-001, PRC-002-2, PRC-019-1, PRC-023-2, PRC-024-2, PRC-025-1, PRC-026-1 and PRC-027-1. As new or revised standards are developed, Electrocon will support those standards within CAPE whenever possible.

In addition to the NERC PRC compliance support, the CAPE-TS Link option allows users to integrate the detailed protection system model of CAPE with the time-domain model of the Siemens PTI PSSE transient stability simulation. The IPS-CAPE Bridge-CIM option provides two-way data exchange between the IPS-RELEX protection system data management software and the CAPE protection system simulation environment, allowing two-way transfer of not only relay settings, but also network topology including CTs and VTs.

Enhancements to CAPE assist our users by allowing them to do their jobs in a more productive manner, stated McGuire. For more than thirty-five years, we have listened to the needs of our customers and developed the necessary tools to support those requirements.

Highly detailed, manufacturer-specific relay models

CAPE is the only protection simulation program that includes highly detailed, manufacturer-specific relay models. Unlike other protection simulation products, Electrocon utilizes highly detailed relay models that can simulate all protection-related functions of a specific relay. Other software packages may say that they include detailed relay models, but what they actually offer are models with some additional basic protection features, but not the supervisory logic, phase selection, fault selection and comparator equations as found in CAPE, stated McGuire. Electrocon engineers model relays using the relay manufacturers specifications, including algorithms that mimic the actual relays operation.

Wide-Area Coordination Studies

The wide area coordination study concept originally developed by Electrocon in the early 1990s is nearly identical to that of the PRC-027 standard requirement. Electrocon developed an automated method for conducting these studies that uses the existing network model as a basis to verify coordination among backup protection devices throughout a high-voltage transmission system. Studies may involve many different types of operating conditions and potential network outages. The variety of conditions, faults, and protective devices which may need to be studied are one of the factors that has made this type of study impractical using manual techniques. Using a well-designed macro to effectively supervise and conduct the entire study, the process results in a high-level summary report (one line of text per fault condition). The summary report simplifies the essential human work of analyzing the results of the study. Today, the wide-area coordination study has become an industry standard and is a tool for utilities around the world to evaluate grid reliability. Electrocon has either conducted or participated in virtually all the wide-area coordination studies that have been conducted to date.

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

CAPEs 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. CAPEs underlying DBMS is fully ODBC- and SQL-compliant; therefore, the CAPE database may be accessed using programs like Oracle and Microsoft Access. All of the CAPE modules use the same CAPE database data, so any data item is entered only once and may be used many times.

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.

About Electrocon International, Inc.

Based in Ann Arbor, Michigan, Electrocon International, Inc. develops and markets CAPE software for protection engineering. CAPE’s graphical network modeling and system simulation support automatic relay setting, detection of miscoordinated settings, and event analysis. CAPE’s is the largest and most detailed library of relay models available. With more detailed, more accurate models, protection engineers study real life conditions, perform wide-area reviews, predict protection system performance, and much more. Electrocon provides ongoing technical support and CAPE-related services for its customers all over the world, which include transmission utilities and engineering firms of all sizes.

Electrocon has been developing tools for computer-aided protection engineering since 1985, working with input from protection engineers from leading North American power utilities. CAPE’s original mission was to create a combined network and protection system model that would support automated relay setting and coordination checking. Today, with a master library of over 5,500 manufacturer-specific relay styles and supported by a true database management system, it is common to see CAPE network models of 2,000 to more than 30,000 buses and protection system models of 5,000 to 50,000 relays. Wide Area Coordination reviews have become a reality as one tool to improve overall power system reliability.
