Dynamic Disturbance Recording (DDR)

Return to Glossary

Dynamic Disturbance Recording (DDR) involves capturing incidents that represent behaviour of the power system during dynamic events, such as low frequency oscillations, abnormal under/over frequency, voltage excursions and system’s wide transients.

DDR can be used for wide-area disturbance monitoring to analyse the system’s transient and post-transient response and predict system model performance.
