Need for the project

​The decarbonisation of energy systems is causing significant and unprecedented changes in electrical power grids, due to the wide-scale introduction of decentralised renewable energy resources. Consequently, future electrical power grids will require real-time capable control and monitoring systems to ensure stability under increasingly complex and challenging conditions. The associated digital high voltage sensors and digital metering systems must be managed through accurate and reliable time synchronisation in a wide area.

New standards in the IEC 61869 have recently been published for low power instrument transformers (LPIT), or are expected to be released for the electronic current and voltage transformers in the future, as well as the for stand-alone merging units (SAMU) in 2018. Due to introduction of these new standards, the movement from traditional analogue instrument transformer (IT) technology towards the new digital instrumentation technology is expected to gain speed, both on transmission (>100 kV) and on distribution (<100 kV) level. To support this change, new metrological tools and methodologies are needed.

Also, test systems are needed to prove performance of intelligent electronic devices, like digital energy meters or real-time critical all-digital PMU’s. 

Lastly, in order to enable industrial uptake and uniformity, active support for standardisation organisations is required to ensure precise measurement also in future digital substations.
