Power Quality Monitoring Infra fürth gmbh - A power utility with Vision

The EN50160 standard describes the main features of power quality supplied by public low voltage and medium voltage distribution systems at the point of common coupling (PCC) under normal operating conditions.

Subject standard specifies the target limits and tolerances of different parameters of the delivered power quality. The standard does not touch typical situations or conditions of public distribution systems. The relevance of a reliable electrical power supply for the national economy and the increasing awareness of the clients for a high availability and a good power quality have been crucial for infra fürth to install a comprehensive power quality management system.

It was looked for an intelligent solution for the data collection and evaluation of measurement values of the power quality. With help of the evaluation software package PAS510 and a adequate number of power quality analysers of type UMG 510 installed across the supply network at the critical supply points and finally networked and connected to a SCADA system with all data transferred to a central operation room it was possible to realize a totally integrated power quality management system

The former analysis was done manually with a high time input. Contents of the analysis was for example the graphical evaluation and comparison of the sequences of the event recording , the data preparation for the Federal Network Agency for Electricity, comparison of the harmonic distortion factors and the load and utilisation of different parts of the integrated network. All these different actions are automatically executed with the help of a totally integrated power quality management system and are much more efficient.
