Abstract

This work introduces a new analysis of voltage sags based on the load variation and the non supplied energy. The power flow variation measured at the transmission level is proposed as an index to evaluate the severity of voltage sags. The correlation between the loss of load and the sag source characteristics, such as type of fault, cause of the fault and location of the fault, can be used for the optimization of transmission network planning and maintenance. Data obtained from actual measurements confirm that correlation and suggest new priorities for utility planners.
