Analysis of Slow Frequency Variations in the Nordic Power System
Slow oscillations in system frequency, with a periodic time of 60-90 seconds and amplitude of 50 mHz, has been observed in the Nordic grid. As a result the frequency is outside the limit of 50 +/- 0,1 Hz more often. It is assumed that this cause wear on turbines and generators. It may also cause add...
