Evaluation of power quality factors on the boundaries between networks

摘要

The present paper describes the general procedures applied in the Romanian Transmission Grid to monitor the main power quality parameters accordingly to the national norms. According to the requirements of the Romanian regulations, a study case was conducted at the 110 kV buses of power delivery from the 400/220 kV transmission network to the distribution subnetworks of a regional power system in order to evaluate the power quality parameters. A software analysis of harmonic propagation in studied transmission network is also included.
