EMPIR 14SIP08
“Standards and software to maximise end user uptake of NMI calibrations of dynamic force, torque and pressure sensors“

05/2015 - 04/2018
New mathematical and statistical approaches are required to address uncertainty evaluation in many modern metrology applications, which are not explicitly covered by existing GUM guidelines. For example, uncertainty evaluation in many emerging or rapidly growing metrology applications, such as biochemical measurements and nanometrology, often poses challenging mathematical and statistical problems. There exists an unnecessarily high risk of incorrect decisions without reliable measurement uncertainty analysis. Many applications demand guidance for conformity assessment beyond current standards. The specific needs in problems demanding inverse methods and regression or computationally expensive systems require a co-ordinated effort to cope with these challenges, to ensure harmonisation and to develop a consistent application framework throughout Europe.

This projects aims at the development of guidelines, tutorial-like journal papers, best-practice guides and publicly available software. The project has already started publishing an open source software repository:

EMRP ENG63
“Sensor network metrology for the determination of electrical grid characteristics“

07/2014 - 06/2017
Methods to observe and control electrical power systems rely on sensor networks and state estimation. The use of these methods to meet the requirements of distribution networks is an active field of research and many challenges remain as networks evolve. Much of this research is carried out only in simulation and often assumes that the topology and impedances of the analysed networks are fixed and known. Further, network conditions that change with time affect the ability of algorithms to function effectively.

This project aims at the further development of a specific quasi-dynamic state estimation method and sensor placement algorithms. A major part of the project is the validation of the algorithms with actual measurement data originating from medium-sized test networks and actually large real networks.

EMRP IND09
“Traceable dynamic measurement of mechanical quantities“

09/2011 - 08/2014
Traceable dynamic measurement of force, torque and pressure as the core mechanical quantities is still challenging and corresponding research has therefore been addressed as an important topic in the EMRP Outline 2008. The lack of traceability prevents industry from making reliable measurements in a range of applications with consequences for safety, quality and efficiency of designed systems. Reliable traceable dynamic measurements would also greatly reduce development efforts and costs, thereby significantly reducing required resources.

The aim of this project was to establish traceability for the three mechanical quantities force, torque and pressure for measurements under dynamic conditions. The required research carried out in this JRP provided the foundation for a European infrastructure for traceable dynamic measurements of these mechanical quantities.
