Distribution FIDVR Events Analysis

This paper presents Fault Induced Delayed Voltage Recovery (FIDVR) events captured in Southern California desert areas during the summer of 2012. This effort is part of an integrated program of FIDVR research sponsored by the U.S. Department of Energy to promote national awareness, improve understanding of potential grid impacts, and identify appropriate steps to ensure reliability of the power system. Southern California Edison (SCE) installed 22 power quality recorders in SCE´s Valley Sub transmission network with the support of the U.S. Department of Energy (DOE). These devices recorded both sinusoidal and rms data from events triggered by voltage excursions. The event data can be used to tune and validate load models and to propose voltage ride through parameters for distributed generation (DG) in particular solar PV inverters.
