Real-life Power Quality Sags

Abstract: 

The distributed generation, along with the deregulation of the Smart Grid, have created a great concern on Power Quality (PQ), as it has a direct impact on utilities and customers, as well as effects on the sinusoidal signal of the power line. The a priori unknown features of the distributed energy resources (DER) introduce non-linear behaviours in loads associated to a variety of PQ disturbances. The aim of the database consists of providing the researchers with a collection of the most common power quality disturbance, real-life sag events, to test experiments and measurement instruments (according the UNE-IEC 61000-4-11: 2005). The dataset provides signals recordings from the power network of the University of Cádiz during the last five years (electrical network according to the UNE-EN-50160: 2011).

One of the main advantages of the dataset it is offer a diversity of real sag events (with a duration off less than 3 seconds) in order to test the performance of the instruments. The signals has been designed from the basis of representative single-isolated events for a network of 50Hz with a sampling frequency of 20 kHz (400 samples per cycle).

The dataset is used as the experimental analysis subject of the interdisciplinary project TEC2016− 77632 − C3 − 3 – R 358 - COntrol and Management of Isolable NanoGrids: Smart Instruments for Solar forecasting and Energy Monitoring (COMING-SISEM), supported by the Spanish Ministry of Economy, Industry and Competitiveness in the work flow of the State Plan of Excellency and Challenges for Research (https://www.researchgate.net/project/COntrol-and-Management-of-Isolable-NanoGrids-Smart-Instruments-for-Solar-Forecasting-and-Energy-Monitoring-COMING-SISEM-TEC2016-77632-C3-3-R). The project involve the development of new measurement techniques applied to monitor the Power Quality in micro-grids.
