A Stable power swing is simulated by disconnecting line 10-11.
According to this figure, the stable power swing causes the impedance trajectory enters into protected zone 3, which could lead to malfunction of the distance relay.
This event causes a stable power swing in the line between buses 1 and 2 and is observed by the relay R. Therefore, distance relay should be blocked by power swing blocker during power swing.
The proposed method presented great accuracy and fast convergence for a wide range of different operational conditions involving transitory events of frequency deviation, amplitude variations, signal phase shifts and stable power swings.
"The trick for me is to try to keep the club face stable through the swing," he said.
With decreasing age children wanted to play with natural materials like sand, water, stable game like swing, slide and mimic and role-playing games.
A long left thumb will be less stable throughout the swing.
Third zone of a distance relay is sensitive to system stressed conditions, such as stable and unstable power swing, voltage instability and load encroachment.
Although the mean ranges of observations were similar to published data for diurnal variation, 4 5 6 greater than normal variability in our data was also designated as "stable"(for example, a swing of 80 mm Hg in systolic blood pressure).
In bipolar disorder, mood swings comprise stable equilibrium dynamics within the diseased regime Emergent properties A complex systemic feature that cannot be explained by the sum of individual system components.
