The estimated number of lightning flashes to a transmission line is the vital parameter to evaluate the lightning performance precisely. An experimental study on the factors that have an impact on the number of lightning flashes to transmission lines has been performed at the MSU High Voltage Laboratory. Models of typical transmission lines with different configurations have been tested under both...
This paper presents a method for placing minimum number of phasor measurement units (PMUs) in a power system in order to locate any fault in the system. A procedure using integer linear programming framework is proposed. Modeling of zero injection bus is also considered. Simulation results for the IEEE 14 bus and 30 bus systems are reported.
This paper presents algorithms to locate faults on a double-circuit transmission line by utilizing sparse current measurements from one or two branches. The branch current is derived as an analytical function of the unknown fault location and fault resistance, and then the fault location can be obtained based on the measured branch currents. The zero-sequence mutual coupling between the two branches...
