DETERMINING STATUS OF ELECTRIC POWER TRANSMISSION LINES IN AN ELECTRIC POWER TRANSMISSION SYSTEM

摘要

The present application discloses systems and methods to determine loss of at least one electric power transmission line in an electric power transmission system. In various embodiments, a system consistent with the present disclosure may include an electrical parameter monitoring subsystem configured to receive electrical parameter measurements and to determine a change of the electrical measurements. An analysis subsystem may determine whether a change in the electrical measurements is indicative of loss of at least one transmission line and may calculate a number of transmission lines lost based on the change. In some embodiments, a remedial action subsystem may be configured to implement a remedial action in response to loss of at least one transmission line. The number of transmission lines lost may be determined based on an angle difference ratio and a power ratio between two buses in electrical transmission system.

1. A system configured to determine loss of at least one electric power transmission line in an electric power transmission system, the system comprising:
an electrical parameter monitoring subsystem configured to:
receive a first plurality of electrical parameter measurements taken at a first location over a period of time;receive a second plurality of electrical parameter measurements taken at a second location over the period of time; anddetermine a change in the first plurality of electrical measurements and the second plurality of electrical measurements over the period of time; an analysis subsystem configured to determine that the change is indicative of loss of at least one transmission line and to calculate a number of transmission lines lost based on the change; and a remedial action subsystem configured to implement a remedial action in response to loss of at least one transmission line.
