Metrology for the 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 Outdated hardware is also being replaced with digital systems needed for so-called smart grids.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 will develop 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 will also assess 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.
