Abstract:
Disclosed herein are a variety of systems and methods for correcting for propagation delay in time signals used in connection with an electric power generation and delivery system. According to various embodiments, a device consistent with the present disclosure may determine an estimated propagation delay between an accurate time source and a receiving device. The propagation delay may be determined based on a variety of transmission parameters including, for example, communication channel type and/or length. A corrected time signal may be generated by advancing a reference incitation such as an “on-time” reference and/or “start-of-second” reference included in the time signal by an amount associated with the propagation delay. The corrected time signal may then be transmitted to the receiving device.
