Optimierung von Planung und Betrieb der Verteilnetze unter Berücksichtigung der Spannungsqualität
AGP

Role: Collaborator

Requérant(e)s: VS - Institut Systèmes industriels, VS - Institut Systèmes industriels

Financement: OFEN

Description du projet : Durch die Integration von dezentraler Einspeisung und Speicherung werden die Verteilnetze stär-ker beansprucht. Netzseitige Massnahmen wirken sich unterschiedlich auf Netznutzung, Verfüg-barkeit und Spannungsqualität aus. Speziell Letzteres wird durch den vermehrten Einsatz von Leistungselektronik und die Veränderung der frequenzabhängigen Netzimpedanz stark beein-flusst. Über Messung und Simulation werden die diesbezüglichen Grundlagen erarbeitet und in einer umfassenden qualitätsgesteuerten Zielnetzplanung angewendet.

Pre-normalisation of grid impedance measurement in the power line communication frequency band
Conference ArODES

Summary:

Power line Frequency and Time dependent Grid Impedance (FTdGI) influences the propagation of the Power Line Communication (PLC) signals and impacts the communication with Smart Meters. The precise measurement of the power line impedance is ill-defined and only possible with a limited number of instruments. This paper presents the results of the Z-NET project aiming to establish a metrological traceable grid impedance standard that enables the objective comparison of the proposed measuring techniques. A Static Impedance Reference (SIR) was defined, built, and characterized. Comparative results of measurements with five different impedance analysers are presented.
