A review of power quality standards, electrical software tools, issues and solutions

Latest innovative ideas to make the life easier using the technology depends upon the application of power electronics in turn on power quality. With increasing quantities of nonlinear loads being added to electrical systems, it has become necessary to establish criteria for limiting problems from system voltage degradation. This paper presents the power quality problems, issues, available electrical software´s, related international standards, the effect of power quality problems. Methods to improve the power quality problems. Also in this paper sampling an overview about electrical software tools, free and commercial software´s.
