Electric energy and supply reliability 23IND01 ENSURE
The amount of electricity generated from renewable sources needs to increase to meet the EU’s aim of becoming carbon neutral by 2050. However, the connection of renewable sources to the power grid causes harmonics which lower network power quality and increase electricity losses in e.g., power transformers and high voltage alternating current (HVAC) cables
The industry thus requires new HV metrology tools to monitor the increased level of grid harmonics, as well as instrumentation to quantify the impact of these harmonics on the efficiency of power transformers and HV cables, plus new methods to evaluate the reliability of high voltage direct current (HVDC) grid connections. Therefore, this project will develop new 1) wideband live connectable current or voltage sensors to monitor and calibrate substation instrumentation, 2) capabilities for determining the power transformer losses that are caused by grid harmonics, 3) methods for determining harmonic losses from HVAC cables, and 4) partial discharge (PD) monitoring techniques for fault detection and location in HVDC cables.
