Micro voltage collapse sometimes occurs when there is a high percentage of low inertia air conditioner (A/C) motors in the power systems. The stalling of the A/C motors results in the phenomenon of fault induced delayed voltage recovery (FIDVR). A hybrid load model including typical building loads, A/C motor loads, and other induction motor loads is built to simulate the A/C motor stalling phenomena...
With the large use of residential air conditioner (A/C) motors during the summer peaks, the potential of motor stalling events have increased in the recent years. The stalled motor loads have been found to be the most important cause of delayed voltage recovery following severe system disturbances, such as a subtransmission fault. The proper modeling of the stalled motors is a very important factor...
