“…This is an additional contribution of the paper, providing an alternative characterisation of real disturbances and a complete comparison with the current grid-code requirements, in terms of both voltage value limits and time intervals. Actually, and in line with other recent contributions of the authors, the severity of the faults is highly dependent on the voltage evolution along the disturbance and the point-on-wave initiation [19,31].…”

In the past few years, grid-code requirements for grid-connected photovoltaic power plants have experienced a continuous evolution in different countries to ensure a reliable power system operation as the level of renewable energy penetration increases to high levels. According to several European grid-codes, PV power plants must be able to ride through specific and severe disturbances without disconnections. Under this new framework, the present study analyses intensive power quality surveys carried out from 2008 to 2011 in three different Spanish PV power plants: a fixed array installation with 4 MW PV power capacity, a PV power plant including dual axis-trackers with 1 MW PV power capacity, and one more fixed array PV power plant with 5 MW PV power capacity. Voltage dips and supply interruptions have been collected, discussing several methods to characterise the monitored disturbances and to compare these events to current Grid-Code requirements. Furthermore, the time interval around the residual voltage is proposed and defined by the authors as an additional parameter to provide a complete characterisation of the severity of the disturbances. Results from both characterisations of collected data and comparison with current requirements are also included in the study.

“…Voltage Dips. Among the PQ voltage variation phenomena, the voltage dips are the most common [15], [22], [23]. Voltage dips are characterized by the duration and the residual voltage [14].…”

“…In [16], more than half of the recorded voltage dips has a time duration less than or equal to 5 cycles and 80 % has a residual voltage in the range between 70 % and 90 %. In [22], most of the events (about 94 %) present a residual voltage equal to 70 % to 90 % and their durations range between 0 ms and 100 ms (5 cycles of 50 Hz). Also, in [24] about 60 % of the voltage dips measured in a 22 kV substation has a residual voltage between 70 % and 90 % and time durations lower than 100 ms.…”

Measurements of Power Quality (PQ) are gaining more importance due to increasing presence of switching power converters that deform the waveform of the distributed voltage further and further away from a sine wave. Especially at medium and high voltage levels, PQ measurements are carried out by means of Instrument Transformers (ITs). A recently started European metrology project, EMPIR 19NRM05 IT4PQ, aims at establishing the methods and procedures for assessing the accuracy of ITs used for PQ measurements. This paper, that is written in the framework of the IT4PQ project, presents a thorough review of the current state-of-the-art of literature and international standards about ITs and PQ. The main results from several papers and the main information from IT and PQ related international standards are summarized.

“…Normalmente se emplean diagramas tridimensionales para representar grácamente los eventos, asignando a cada las variables tensión ecaz residual, duración del hueco y número de eventos respectivamente. Una vía alternativa para sintetizar y mostrar las perturbaciones se encuentra propuesta en [119]. Este tipo de representación, llamado mapa de colores, clasica las perturbaciones en sectores rectangulares.…”
