IVESCO: ready to support CAPE customers in Mexico

A group of engineers from IVESCO S.A. (www.ivesco.us) in Mexico City has completed five days of advanced CAPE training at Electrocon's Ann Arbor, Michigan office. The group is now even better prepared to support the growing group of CAPE customers in Mexico. In addition to serving ongoing first-line customer support needs, the IVESCO group will offer introductory CAPE training.

CAPE supports automated sensitivity testing to prevent relay miscoordinations

With Sensitivity Testing, utilities can now take proactive steps to prevent relay miscoordinations. Read more.

Technical paper: “Challenges Encountered in the Operation Analysis and Settings of a Parallel Three-Terminal Line Application”

Electrocon International exhibited CAPE software for protection engineering at the Western Protective Relay Conference.  On the conference program, Jeffrey Pond, National Grid, presented the paper, “Challenges Encountered in the Operation Analysis and Settings of a Parallel Three-Terminal Line Application,” which describes an event experienced by National Grid: an over trip of a Directional Comparison Blocking (DCB) Scheme on a 115 kV double-circuit mutually coupled line for a transformer lightning arrestor failure on a parallel, three-terminal line with an identical DCB scheme. The post-fault investigation identified the root cause of the event and showed several key requirements for effective protection tools. Request a copy of the technical paper or read more info.

Practical approach to Wide-Area Coordination Review

Electrocon International has pioneered an innovative methodology to automate the wide area coordination review of a utility’s protective devices. Automation has made this clearly desirable objective both practical and affordable, where previously it was an ideal that even fully-staffed protection groups could not achieve. The transmission utility does not need to have Electrocon’s CAPE software and relay database in place, since the technique can be applied to data converted from almost any existing electronic network format, including those of Siemens’ PSS/E and ASPEN’s OneLiner.

Technical paper: Protection coordination in the transmission system and boundaries – a Wide-Area Coordination study

A technical paper presented at WPRC 2007 describes the methodology to automatically check a wide area of protection coordination, including the boundaries between transmission and generation and transmission and distribution. 

This paper describes Red Eléctrica de España (Madrid)'s 2006 project to check protection coordination in one of its most critical transmission network areas. More
