초록
Voltage Sags, different from electric outages, are important to industrial reliability because modern process controls are often sensitive to voltage sag, the designer and operator should recognize sag characteristics of the electric system not only to protect malfunction of equipment but also to make best choices between reliability and equipment cost. The voltage sags and compensation countermeasures of large md industrial distribution systems have been simulated using EMTDC. The causes of voltage sags occurred in the system are discussed in detail and several countermeasures including the transfer of large induction motor from normal power source to backup source are recommended in order to enhance the ride-through characteristics of equipments.
