Architecture of the Modern Power Quality Monitoring Systems with Installation and Experiences Examples from BiH, Croatia and Slovenia

Abstract

The quality of supply and reliability of the grid are main investments reason in electrical grid. To keep the track of the power quality it’s necessary to develop power quality monitoring system. Development of power quality system requires deep analysis of customer grid to properly select points of installation and project with clear goals and requirements for monitoring system. Implementation of the power quality system depends on the type of the electrical grid and existing communication infrastructure. The new system need to be compatible with all up to date technologies and provide data protection and access control. Beside the basic power quality indices, it needs to offer integration with other utilities systems like SCADA and fault location systems to improve response and benchmarking of the system.
