Relaying Upgrades in Six 69kV/12.47kV Substations for Reedy Creek Improvement District (Lake Buena Vista, Florida)

As part of a reliability enhancement initiative, Reedy Creek Improvement District (RCID) selected FW&A to prepare designs for the installation of new SEL microprocessor-based relays and associated control panels for 97 distribution circuit breakers in six substations. FW&A developed all relay settings and designed a fiber-optic communication system to support the new equipment. Designs also included the addition of multifunction power meters to each substation's main breakers to provide RCID with independent transformer metering information. The firm provided on-site construction verification, startup and commissioning assistance and revision of operation and maintenance documentation. Because the utility supplies power to several major tourist attractions, FW&A engineers performed all field work after normal operating hours to avoid any risk of high-cost electrical service interruption.

For more than 15 years, FW&A has designed relaying projects throughout the 12.47kV distribution system owned by Reedy Creek Improvement District.

Relaying Upgrades for Distribution Automation in 27 Substations for JEA (Jacksonville, Florida)

In order to increase power quality and reliability to its 100 largest customers, JEA initiated a 26.4kV system-wide distribution automation program. The utility selected FW&A to design protective relaying upgrades in 27 substations for all main and critical-load feeders and to interface the upgraded relaying with JEA's SCADA system. The project also included new load tap changing equipment (LTCs) and power meters on 86 transformers.
