ASTROSE News

This year, Fraunhofer IZM will once again be presenting its ASTROSE power line monitoring system at CIGRE—this time not in Paris, but in Montreal, Canada! As the world's leading congress for high-voltage technology, the CIGRE Symposium once again offers IZM a stage to present the latest developments in our system to an international audience of experts. At the accompanying technical exhibition, we will be demonstrating the latest ASTROSE functionalities at booth 322. This year, the focus will be on further developments in the dynamic assessment of overhead lines (DLR).

Visit us at our booth 146 at CIGRE www.cigre-exhibition.com, the leading international congress for high voltage technology, which will take place in Paris from 26.8. to 30.08.2024. At the accompanying technical exhibition we will present the latest functionalities of our Power Line Monitoring System ASTROSE. Our highlight topics this time will be ice detection and increasing the current carrying capacity. We would be very pleased to welcome you there during the event days.

For weather-dependent overhead line operation, the reliable determination of the sag within a span, which is dependent on the line temperature, is of crucial importance. An integral method for this is to measure the sag angle from the suspension or tension clamp.

On December 1, 2023, the ASTROSE-MoNet research project “5G monitoring platform for high and extra-high voltage grids to support the goal of net-zero emissions in smart grids” will start with the partners DResearch Digital Media Systems GmbH, Pfalzwerke Netz AG, LTB Leitungsbau GmbH, Technische Universität Berlin and the Fraunhofer Institute for Reliability and Microintegration.

Visit us at our booth 218D at CIGRE www.cigre-exhibition.com, the leading international con-gress for high voltage technology, which will take place in Paris from 29.8. to 02.09.2022. At the accompanying technical exhibition we will present the latest functionalities of our Power Line Monitoring System ASTROSE. Our highlight topics this time will be ice detection and increasing the current carrying capacity. We would be very pleased to welcome you there during the event days.

In the Harz foothills and western Harz region, Harz Energie Netz GmbH www.harzenergie-netz.de from Osterode operates a high-voltage grid that is continuously operated with an operating voltage of 110 kV. The entire network supplies 150 localities.

The Forum Netzbau und Netzbetrieb (Leitungsbautagung) will take place this year on May 12 and 13 in Hamburg at the Hotel Grand Elysee www.tagungsgesellschaft.de/programm.

With its current sensors, the ASTROSE system already offers a comprehensive range of available measured values around the conductor rope. This includes a highly accurate current measurement (+/-1A) as well as a voltage measurement (+/-1kV) with the derived quantities of phase angle and reactive power.

In order to meet the energy transition and the associated challenges for the infrastructure, Pfalzwerke Netz AG www.pfalzwerke-netz.de has successfully invested in the development of the low-power data transmission technology LoRaWAN.

Four different radio solutions are now available to the ASTROSE system, depending on the application environment and requirements, which are optimized in particular with regard to energy requirements, range and data throughput.
