The monitoring of systems and electrical grids is an important part of the changing grid structure on the way to the SMARTGRIDS of the future. It pursues different objectives
- Reduction of maintenance and repairs
- Increasing reliability
- Better utilization of grids
- Longer service life of components
In contrast to pure measuring systems, monitoring systems are able to evaluate the condition of a system or network and automatically trigger appropriate measures if necessary.
The diagnosis of insulating materials is used for quality assurance during production and fault prevention during the operation of a system. A typical diagnostic method for off-line and on-line applications is partial discharge analysis.
The AHT department conducts research in various projects on the subject of monitoring and diagnostics:
- Monitoring of disconnectors and circuit breakers (cooperation with AREVA-Kassel 2004-2008)
- Real-Time Identification and Monitoring of the Voltage Stability Margin in Electric Power Transmission Systems Using Synchronized Phasor Measurements (Diss. Y. Nguegan Tchokonte, 2009 in Co-operation with Energinet DK)
- Diagnosis of electric traction motors using partial discharge measurement technology under pulsed voltage stress (Diss. Dr.-Ing. Amir Berbic, 2014)
- Satellite navigation receivers and systems for autonomous mobile applications
- Sensor technology for automated monitoring and diagnosis of high-voltage overhead lines with aerial platforms (UAVs)
