Abstract

This paper focuses on testing the dynamic behavior of single-phase air conditioner motors on distribution power networks. The primary goal is to study the phenomenon of delayed voltage recovery by applying multiple instances of a custom-built single-phase induction motor model on a given distribution feeder. This model was developed in an Electromagnetic Transients Program (EMTP) simulation environment. The motors were subjected to voltage disturbances seen in feeders experiencing the fault-induced delayed voltage recovery (FIDVR) phenomenon. To study the FIDVR phenomenon, a range of voltage depressions were simulated for predetermined system conditions. This paper describes a point-on-wave model development and simulation study that supports a broader investigation of the effect of air conditioning and similar loads on the recovery of electric utility voltage after faults.
