    摘要： A system for controlling and automating an electric power delivery system by executing time coordinated instruction sets to achieve a desired result. A communication master may implement the execution of time coordinated instruction sets in a variety of circumstances. The communication may be embodied as an automation controller in communication with intelligent electronic devices (IEDs). The communication master may also be embodied as an IED that is configured to coordinate the actions of other IEDs. The time coordinated instruction sets may include steps for checking status of power system equipment before executing. The time coordinated instruction sets may include reactionary steps to execute if one of the steps fails. The time coordinated instruction sets may also be implemented based on a condition detected in the electric power delivery system, or may be implemented through high level systems, such as a SCADA system or a wide area control and situational awareness system.

    摘要： Systems and methods providing resampling of a sampled data transmitted through a communication channel. Reliable resampling is provided even when original data samples are lost or reordered during transmission through the network. In one embodiment, a receiver associates each received data sample with a respective sampling time instant. The received data may include index values that associate the received data samples with respective sampling time instants. In other embodiments, the received data includes time stamps with encoded sampling time instant information. In another embodiment, arrival time instants are used to correlate the received data samples with their respective sampling time instants. The receiver then uses the sampling time information to select data samples corresponding to resampling time instants. If needed, the receiver uses interpolation to generate resampled data points corresponding to the resampling time instants.

    摘要： Provided is a self-calibrating time code generator and method for generating an accurate time code (e.g., an accurate IRIG waveform). The self-calibrating time code generator includes a phase-locked loop configured to provide a generated output signal based on a phase difference between an absolute time reference signal and a compensated generated input signal, an IRIG encoder configured to couple a present time value with the generated output signal to form an IRIG waveform, a delay difference indicator configured to provide a time interval value based on a comparison of corresponding pulse edges of the generated output signal and the IRIG waveform, and a numerical delay component configured to delay the generated output signal by the time interval value to form the compensated generated input signal used to time-align the IRIG waveform with the absolute time reference signal to form the accurate IRIG waveform.

    摘要： The system for synchronous sampling uses an encoded time signal, such as an IRIG-B signal. The IRIG-B signal is applied to an edge detector, which produces pulses based on the edges of the encoded time signal. These signals are applied to a phase-locked-loop assembly which is arranged to produce an output sampling synchronization signal which is locked to the transitions in the encoded time signal, providing a synchronous control signal for data sampling of input signals to a plurality of electronic instruments, in addition to the use of the IRIG-B signal as time-of-day clock synchronization for the plurality of instruments.
