This paper presents Fault Induced Delayed Voltage Recovery (FIDVR) events captured in Southern California desert areas with residential distribution circuits. Southern California Edison (SCE) installed 22 power quality recorders in SCE's Valley Subtransmission network. These devices recorded both sinusoidal and rms data from events triggered by voltage excursions. The purpose of this project is to acquire FIDVR data to validate WECC's composite load model. This data will support the load composition analysis in the WECC composite load model as well. The sinusoidal data can be used to validate transient models of stalling residential air conditioners. 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. The key results presented are associated with the stalling behavior of the air conditioner units in SCE's Valley substation region.
