Claim 0:
1. A system to detect lightning and to control at least a portion of an electric power system, the system comprising:
a data acquisition subsystem configured to receive a plurality of representations of electrical conditions associated with at least a portion of the electric power system;
a traveling wave subsystem to:
identify an initial traveling wave generated by lightning and traveling in an electrical conductor configured to provide electric power as part of the electric power;
open a detection window upon detection of the initial traveling wave;
monitor for at least one subsequent traveling wave during the detection window; and
identify the at least one subsequent traveling wave generated by lightning and traveling in the electrical conductor configured to provide electric power as part of the electric power;
a lightning analysis subsystem to perform an analysis of the initial traveling wave and the at least one subsequent traveling wave and to determine:
an ionosphere characteristic based on the analysis; and
a lightning location; and
an adaptive control subsystem to adjust a control strategy based on the lightning location and during the detection window;, wherein, the adjusting of the control strategy comprises blocking an automatic reclosure algorithm following a trip, and the adjusting of the control strategy is retrained to reduce the risk of fire.
