Electrical Power Quality - Voltage Dips

This dataset presents the analysis of voltage dips on MV busbars in HV/MV substations, according to the classification table in NP EN 50160. For each monitoring point, the following information is presented: Number of voltage dips in each cell of the table, for the indicated period, excluding exceptional events and high-impact incidents in the process of classification as exceptional events. Number of voltage dips in each cell of the table, during the period of each exceptional event and high-impact incident in the process of classification as exceptional events. Polyphase aggregation (IEC 61000-4-30) and a 3-minute time interval are considered. The data are updated annually. These data result from the application of successive biannual monitoring plans for a set of selected points in the distribution network. Point selection 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 ───────────────────┬───────────────────────────────────────────────────────────────────────── Swell Voltage u (%)│Duration t (ms) ├────────────┬─────────────┬──────────────┬───────────────┬─────────────── │10 ≤ t ≤ 200│200 < t ≤ 500│500 < t ≤ 1000│1000 < t ≤ 5000│500 < t ≤ 60000 ───────────────────┼────────────┼─────────────┼──────────────┼───────────────┼─────────────── 90 > u ≥ 80 │Cell A1 │Cell A2 │Cell A3 │Cell A4 │Cell A5 ───────────────────┼────────────┼─────────────┼──────────────┼───────────────┼─────────────── 80 > u ≥ 70 │Cell B1 │Cell B2 │Cell B3 │Cell B4 │Cell B5 ───────────────────┼────────────┼─────────────┼──────────────┼───────────────┼─────────────── 70 > u ≥ 40 │Cell C1 │Cell C2 │Cell C3 │Cell C4 │Cell C5 ───────────────────┼────────────┼─────────────┼──────────────┼───────────────┼─────────────── 40 > u ≥ 5 │Cell D1 │Cell D2 │Cell D3 │Cell D4 │Cell D5 ───────────────────┼────────────┼─────────────┼──────────────┼───────────────┼─────────────── 5 > u │Cell X1 │Cell X2 │Cell X3 │Cell X4 │Cell X5 ───────────────────┴────────────┴─────────────┴──────────────┴───────────────┴─────────────── The data relating to the periods of exceptional events is not yet available in Open Data. 1. The information provided by E-REDES is an approximation of the values related to substations and the MV network as they are extracted from the systems and are based on the time the information was collected. 2. Given that the connection points, the electricity distribution network, and the consumption and production values themselves are naturally very dynamic, please note that the information provided may be subject to subsequent changes and updates, and reserves the right to accept any omissions and/or occasional location inaccuracies that the information may contain. 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 purpose of formulating regular grid connection requests (PLR). 4. E-REDES ensures that the information provided does not imply connection to any specific network 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.
