Power quality and metering monitoring applications for smart network operations

Romanian TSO/DSO performed the necessary steps to implemented a nationwide Power Quality Monitoring System(PQMS) / Metering Monitoring System(MMS). First results encouraged us to consider grid extended PQMS and MMS as emerging data provides for the development of smart grids technology. The first part of the paper provides a description of the Power Quality(PQ) and Metering Romanian regulations. The second part presents the new PQMS hardware, software architecture and the most important results. The third part presents in particular the concepts and application aspects of effective power monitoring tools that are being used to visualize and analyse the power network of Romania. The final part contains conclusions and recommendations for future development.
