Abstract

In power system control, the responsiveness of the measurement infrastructure can be assessed by means of several metrics. Technical specifications and product standards have introduced performance metrics such as delay time, which should account for the time necessary to react to a sudden change in the input signal. On the other hand, the trustworthiness of the measurement result should be evaluated also during abnormal conditions. In this paper, we consider two different implementations of a PMU prototype, and we assess its responsiveness in terms of two metrics: delay time and trustworthiness. To this end, we characterized the two PMU implementations by means of extensive simulated and hardware-in-the-loop tests. The preliminary results confirm that the combination of delay time and trustworthiness metrics represent a valuable input for setting up more robust and effective control routines.
