Software and hardware equipment power quality monitoring inside a transelectrica high voltage power station

This paper presents a dedicated software (as well as the associated hardware) used for power quality analysis. Power quality is one of the important objectives of the transmission and distribution network allover the world. Several aspects concerning the PQ monitoring interface between the transmission network and the distribution network are revealed for a 110 kV voltage level. This is a case study for the current situation and for the perspective. The system used for the power quality monitoring parameters (software and hardware) is described as applied on a representative substation within the Romanian Power System (Iernut substation).
