A method for synchronization of two stationary clocks located respectively at a first and a second end of an AC power line. The two clocks are initially synchronized to within a period of a line frequency of the power line. A first representation of an oscillating power line quantity is produced by measuring the power line quantity at the first end of the power line and time-stamping the first representation by the first clock. A second representation of the oscillating power line quantity is produced by measuring the power line quantity at the second end of the power line and time-stamping the second representation by the second clock. The first and second representations are compared to determine a clock offset between the first and second clocks. One or both of the first and second clock or at least the first clock is then adjusted to reduce the clock offset. |
