Fault Induced Delayed Voltage Recovery (FIDVR): Modeling and Guidelines


Voltage sensitive loads are broadly classified as static or steady state, and dynamic load types. After several years of research and development, Bonneville Power Administration (BPA) and Western Electricity Coordinating Council (WECC) developed the Composite Load Model structure comprising of different types of static loads, electronic loads, three phase and single phase compressor motors. Single phase compressor motors are the main drivers of the phenomenon termed as Fault Induced Delayed Voltage Recovery (FIDVR). In the present work, we developed a computer simulation model in GE PSLF that could replicate the FIDVR event in the Valley substation of Southern California Edison (SCE) that occurred in 2004. We also performed some sensitivity analysis of various parameters of three-phase and single phase compressor A/C motor loads and produced a guideline showing some typical values of different parameters to replicate the real world FIDVR events. At last, we have presented a broad guideline for steady state cascading simulations. This paper is based on a project report prepared for the CEATI International Power System Planning and Operations Program, which consists of North American electrical utilities focused on Transmission Systems.
