A METHOD AND APPARATUS FOR TRANSMISSION BRANCH SWITCHING FOR OVERLOAD MITIGATION

摘要

In one embodiment, the present invention relates to a method and device for selecting a transmission branch from a plurality of transmission branches in a power system. At least one overload in the power system is detected. At least one radial branch and critical branch are eliminated from the plurality of transmission branches to obtain a first set of transmission branches. At least one pair of analog and digital parameters for each of the plurality of transmission branches are calculated, compared with one or more thresholds and the plurality of transmission lines are filtered to obtain a second set of transmission branches. An outage is simulated in the power system and stability of power system is checked based on one or more dynamic constraints to identify and eliminate a weakest branch from second set of transmission branch. Rank of the second set of transmission branches is rearranged and a transmission branch is selected for switching.
