time delay, VVO CL, regulation resourcesAbstract
In this paper the signal trajectory during the command of a telemetric point and VVO CL function execution was discussed. The types of time delay as well as the time delay that occurs during the command and execution of the VVO CL function are considered. Also taken into account is how and in what way the time delay affect computation and system oversight and commanding does. The calculation of time delays were conducted based on the acquired time delays.
