Abstract

This paper presents the correlations of voltage sags between the transmission system and the distribution system. The studies included the effect of the transformer connections. Rotchana substation of Provincial Electricity Authority (PEA) has been selected as the case study. It receives power from 115 kV transmission systems and distribute to customers in 22 kV distribution systems. The studied network is simulated by PSCAD/EMTDC program and also the voltage sags data recorded by the power quality meters are used in the analysis. Finally, the results are proposed and discussed.
