Digital-IT Objectives
The overall goal of this project is to develop the metrology infrastructure for the traceable measurement and calibration of digital substation instrumentation (i.e., SV enabled equipment such as SAMUs, digital instrument transformers and instrument transformer measuring bridges).
The specific objectives of the project are:
- To develop and calibrate reference systems (hardware) for calibration of SV enabled equipment, covering the new requirements of recently released IEC standards. To develop new hardware for traceable measurement of new data rates up to 96000 samples per second (SPS), for the related measurement bandwidth up to c. 40 kHz.
- To develop software for controlling the setups and handling of SV data streams and develop new data processing and uncertainty estimation approaches for new data rates up to 96000 SPS.
- To develop communication and timing networks, in participating laboratories, by creating ethernet networks that will transmit SV data and Precision Time Protocol (PTP)-based timing between commercial devices. To establish a traceable link between PTP timing and 1PPS (One Pulse Per Second) reference pulse with a target uncertainty of 100 ns.
- To provide the data, methods, guidelines and recommendations, which are necessary for the calibration of SV enabled equipment, to IEC TC 38. To integrate the plans for future research activities on the European Metrology Network for Smart Electricity Grids (EMN SEG).
- To contribute to the standards development work of the technical committee IEC TC 38. Outputs will be in a form that can be incorporated into future standards at the earliest opportunity and will be communicated through a variety of media to the standards community and to end users (equipment manufacturers, transmission system operators (TSO), distribution system operators (DSO), and customers).
