要約(日本語): Nowadays, more sensitive electronic equipment is widely used in modern power systems such as power converters and adjustable speed drivers. Power quality has been a greater interest in voltage sags due to their impacts on the performance of sensitive equipment (SE). Malfunction or failure of the equipment that leads to work or production losses can be caused by voltage sags. Recloser and fuses are the main overcurrent protection devices in distribution systems. Poor coordination could adversely impact on the sensitive equipment. This paper presents a method to analyze the impacts of voltage sags and protection coordination on sensitive equipments. Based on the results, new settings for protective devices are done to consider sensitive equipment in distribution systems. The Roy Billinton Test System (RBTS) bus 2 is used to analyze the impact of voltage sags and protection coordination system on the sensitive equipments in distribution systems.
