Abstract

This paper investigates the challenges in developing a performance index that will reflect the level of power quality at a site based on the actual field data obtained from the site via power-quality (PQ) monitors. For the index, each observed voltage variation is assessed in terms of its potential to impact the customers served from the site. The paper considers the substation level PQ monitoring and adopts a procedure that is similar to one of the methods being proposed in the emerging IEEE guide 1564.
