RESUMO

This work presents a review of the methodology used in PRODIST 2010, and alternative proposals for setting targets and rates depending on quality of service (QoS). All analysis are supported in statistical interruption data studies of 6 electricity distribution companies (EDC) between 2007 and 2008 with different characteristics of DEC, FEC, number of users and sets. The first proposal called Single Rate - Single Goal (TAMU in Portuguese) proposes the same goal of QoS to all same voltage level users. This proposal sets as a general criterion that 10% of users with worst voltage level attendance must be compensated for getting poor QoS. In order to achieve this goal, the top voltage levels of each company were determined from its cumulative frequency histograms of the user individual indicators value. This procedure guarantees the same percentage of users compensated in all EDC voltage levels. The results obtained by calculating the average penalty per user refunded maintain a fairly consistent with deterioration of collective indicators values (this does not happen in PRODIST 2010), where EDC with worst performances will pay a higher average penalty per user. The second proposal describes a different discount rate methodology (TARDIF in Portuguese). In this methodology, the DIC of users with same voltage level were classified into five intervals of its collective average (DEC). The last three classification intervals correspond to users who have had the worst QoS in the year. For these users were defined discount rates that would compensate the losses next year. In the obtained results, the average penalties of refunded users maintain the relationship between the average attendance and the data scattering, being the last one the most dominant criterion.
