“…Triggering using the AC signals is based on the PQ analysis of the three-phase waveforms and is performed by sending the acquired samples to a PQ server that uses CIRCE's libPQ library [16]. This library implements online Power Quality analysis following the stringent class-A requirements of the IEC 61000-4-30 [17] standard.…”

The presence of DC grids in distribution networks is being increased nowadays and is expected to be quite relevant in a near future, due to several advantages compared to traditional AC systems. Regardless of this, Power Quality in DC grids (DC PQ) (voltage variations, transients, spectral components, etc.) still remains not properly considered and there is a lack of reference normative documents such as standards, application guides or technical reports for their application. In this context, it is necessary to obtain more experience on real measurements, in order to define appropriate DC PQ parameters and limits that assess a reliable operation of the whole power network and eventually lead to establishing a reference frame acceptable for both generation sources and final users. In this work, a novel high frequency (up to 4 MS/s) digitiser system is presented for the study of DC PQ events. The system is designed to acquire waveforms with triggers fired by events in both DC and AC signals. The captured signals are pre-processed in real-time to be able to recover pre-trigger information stored in memory. The system was installed in a real DC micro-grid and configured to take data in an unattended way. Additionally, the results of the first months of data acquisition are presented.

“…The three-phase AC PQ triggers are based on the analysis of PQ indices computed according to IEC 61000-4-30 [17]. The CIRCE's libPQ library [16] has been used, as it is capable of providing the following: power frequency, supply voltage magnitude, flicker, voltage harmonics, dips, swells and interruptions.…”
