    摘要: The disclosure is related to a method, power control device and computer program product for evaluating accuracy of timing provided by time generating equipment in relation to wide area control in a power transmission system, where the wide area control is performed based on time stamped measurements of system data. The power control device can include a timing deviation handling unit that investigates timing used in relation to time based measurements, determines if the timing is reliable or not based on the investigation, and aborts wide area control if the timing is deemed unreliable.

    摘要: A method and controller are provided for the compensation of time delays in remote feedback signals in power system control. The method includes converting the time delay into a phase shift and calculating four compensation angles from the phase shift. The optimal compensation angle is determined and applied to the remote feedback signals. A technique of equipping a controller with a global clock is also disclosed.
