Abstract

Voltage sags affect many more customers than momentary interruptions do. The sags on a distribution feeder are likely to result in damage to a customer´s sensitive equipment on all of the adjacent feeders. It is essential to understand the characteristics of sags in order to determine the most suitable distribution feeder configuration and equipment specifications. In this paper, the development and implementation of an integrated software tool for voltage sag analysis is presented. It integrates the available historical outage data, analytical calculation algorithm and advanced computer graphic capabilities together to provide valuable voltage sag information. State-of-the-art software technologies are used to ensure the effectiveness, openness and flexibility of the integration approaches. Initial field experiences at PG&E (USA) have indicated a great demand of such an informational tool
