This dataset presents the voltage compliance analysis of MV busbars in HV/MV substations and LV busbars in distribution transformer stations, meeting the limits established by NP EN 50160.For each monitoring point, the following information is displayed for each voltage characteristic (rms voltage value, flicker, total harmonic distortion, unbalance, and fundamental frequency):Percentage of compliant values ​​for the indicated period, excluding exceptional events and high-impact incidents in the process of classification as exceptional events.Percentage of compliant values ​​during the period of each exceptional event and high-impact incident in the process of classification as exceptional events.For harmonic voltages with limits established by NP EN 50160, the minimum overall compliance percentage is presented.If it is a Substation:Voltage L1: Voltage RMS values L1-L2Voltage L2: Voltage RMS values L2-L3Voltage L3: Voltage RMS values L3-L1Flicker Plt L1: Flicker Plt L1-L2Flicker Plt L2: Flicker Plt L2-L3Flicker Plt L3: Flicker Plt L3-L1THD L1: Total harmonic distortion THD L1-L2THD L2: Total harmonic distortion THD L2-L3THD L3: Total harmonic distortion THD L3-L1If it is a PTD:Voltage L1: Voltage RMS values L1-NVoltage L2: Voltage RMS values L2-NVoltage L3: Voltage RMS values L3-NFlicker Plt L1: Flicker Plt L1-NFlicker Plt L2: Flicker Plt L2-NFlicker Plt L3: Flicker Plt L3-NTHD L1: Total harmonic distortion THD L1-NTHD L2: Total harmonic distortion THD L2-NTHD L3: Total harmonic distortion THD L3-NThe data are updated annually.These data are obtained from the application of successive biannual monitoring plans for a set of selected points in the distribution network. The selection of points takes into account a balanced geographic distribution, as well as the identification of customers as being more susceptible to voltage quality variations, according to the RQS.1. The information provided by E-REDES constitutes an approximation of the values ​​related to substations and the MV network as they are taken from the systems and are based on the time at which the information is collected.2. Given that connection points, the electricity distribution network, and consumption and production values ​​themselves are naturally highly dynamic, the information provided may be subject to subsequent changes and updates, and any omissions and/or occasional location inaccuracies that the information may contain are also taken into account.3. The information provided by E-REDES is merely an approximation of the available network capacity at any given time. Therefore, it does not constitute a contractual proposal, nor does it replace consultation with E-REDES for the purposes of formulating the usual grid connection requests (PLR).4. E-REDES ensures that the information provided does not imply connection to any specific grid point or asset, or even to a specific solution within the scope of the PLR ​​that may be proposed. E-REDES reserves the right to evaluate the most appropriate technical solution on a case-by-case basis, based on the respective requests, in accordance with the principles to which it is legally bound.5. E-REDES is not liable to third parties, including partners, service providers, contractors, users, and customers, for any damages that may arise directly or indirectly from the use of this Information, particularly when performing interventions, calculations, and/or estimates without confirming the accuracy and updating of the data. Therefore, it is duly noted that consulting this information does not prejudice the obligation to consult E-REDES directly for updated information.6. The information provided is, for all legal purposes, the property of E-REDES and may not be copied, reproduced, adapted, modified, altered, deleted, destroyed, disseminated, transmitted, disclosed, or otherwise made available to third parties without expressly authorizing it. Any reproduction, commercialization, or transfer to third parties, even free of charge, outside the specified terms or without the express authorization of E-REDES, is prohibited under applicable law and may result in civil and criminal liability.The data provided by the E-REDES Open Data Portal is covered by open licenses (CC BY 4.0).
