In addition to the gear’s ruggedized physical and electrical attributes, this particular application represents the first known use of the industry-leading SEL-487E relay for distributed I/O automation functions beyond the scope of its original design. The facility’s serving utility, Central Lincoln People’s Utility District, installed Trayer 3805 Series medium voltage switchgear to protect their distribution system from a failed transformer or other system fault/overcurrent condition. Newport, OR is the site of NOAA’s new Marine Operations Center-Pacific, a 24/7/365 mission-critical facility with global maritime responsibilities. Trayer Engineering Corporation highlights a new, cutting-edge distribution automation application with the publication of its latest case study. Utility installs a Trayer 6-Way SCADA Vacuum Fault Interrupter (VFI) to provide ruggedized 15kV service to NOAA’s new facility in Newport, OR case study describes industry’s first implementation of SEL-487E control relay’s full automatic transfer potential using multiple distributed I/O. Designed for extended service life under harsh environmental conditions, Trayer’s 3805 series of storm-hardened switchgear ensures power availability for this mission-critical facility.ĭownload NOAA/Central Lincoln Case Study (PDF 2MB)Ĭase Study Describes Trayer Storm-Hardened Switchgear’s Unique Distribution Automation Solution at NOAA’s Pacific Fleet HQ Detect system separation to initiate islanding control.The NOAA MOC-P facility in Newport, Oregon provides global communications and high-performance computing operations on a 24/7 basis.Apply SELogic control equations to time-correlated remote measurements.
Control tap position based on combined values.Trip or start generators based on system load angles.This advanced SEL-487E Relay communications technology allows customers to: 'Large generators and transmission stations that frequently use this type of relay can now easily apply remote measurements to control tap changers, regulate generator voltage, and notify operators of system conditions.' 'A multirestraint transformer differential relay, such as the SEL-487E, is an ideal platform for synchrophasor-based control,' said Roy Moxley, SEL marketing manager for synchrophasors. Remote angles, currents, and voltages received in the serial synchrophasor message can be combined with local measurements for basic or advanced applications. This enhancement to the allows it to receive IEEE C37.118 synchrophasor messages from up to two phasor measurement units, time-correlate the information, and take control actions based on local and remote messages.
