The power quality and efficient use of electricity generated. Romanian energy market case study

This paper presents an on-line system used for monitoring power quality, transferred from producers up to distributors on the Romanian energy market. The system allow the analysis of methods and means for making all maintenance works inside transformer power stations, belonging to TRANSELECTRICA S.A., the National Company for Power Transport, at high efficiency. Monitoring the power quality indicators, performed via dedicated analyzers, portable or fixed, facilitates compliance to standard limits and create the database required for the completion and correction of the standards. As a study case it is used a representative substation within the Romanian Power System (220/110/20 kV Ungheni Substation).
