Assessment of the critical clearing time in low rotational inertia power systems
conference contribution
posted on 2018-06-20, 15:18 authored by Francisco Gonzalez-LongattFrancisco Gonzalez-Longatt, Jose L. Rueda, Dimitar BogdanovThe growing share of power electronic/converter interfaced generation is decreasing the total system rotational
inertia. The reduced rotational inertia in the power system has important impact on the electro-mechanical processes, the power
angle and frequency evolution time are quicker resulting in faster transient processes. Rapid response of the protection systems shall be applied, in order to clear the faults in the power systems. This paper aims to identify the roots/mechanism of critical clearing time reduction/deterioration by determining/analyzing the trajectories of the critical clearing time (CCT) in low
rotational inertia power systems. In this paper, the equal area criterion (EAC) is used for analysis purposes. Theoretical and
practical findings demonstrate the increase of the rotational inertia increases the CCT.
