Measurements for next-generation digital substation instrumentation


The electrical power industry is faced with significant technical challenges as generation from more widely distributed, and less predictable, renewable energy sources displaces fossil fuels. Outdated hardware is also being replaced with digital systems needed for so-called smart grids.

By monitoring the modern power grid with greater accuracy, a better managed and more reliable electricity supply can be delivered to the consumer.

 

This project developed the calibration methods needed for the new digital hardware used in networks for power transmission and distribution; greater accuracy will be achieved, with measurements traceable to primary standards held by National Measurement Institutes.

Because synchronization and accurate measurement timings are critical for the operation of a smart grid, the project  also assessed existing timestamping methods.

To encourage uptake of the results from this project, both industry and standards organisations will be informed through workshop events, journal papers and good practice guides.

 

This project builds on from EMRP project ENG61 FutureGrid and EMPIR project 21NRM02 Digital-It further builds on this work.
