Analysis of quality from customer’s and renewable sources point of view

Abstract

There are summarized some parameters of electric energy in this article. Their exceeding leads to complaint on quality of supplied electric energy. Further are stated some of electro-technical solutions of wind turbines which have specific influence on produced energy. Present energetics is trying to increase amount of renewable resources power stations because of bottomless potential of renewable energy. This boom is worldwide and because quality of electric energy is one of the reasons of complaints, it is necessary to examine it and investigate reasons of breakdowns and non-supplies, which are leading to fairly big economic losses etc. There is interensting valuation of relationship between amount of complaints and installed outcome from renewable resources (wind, sun, water) in locations where energy is supplied by CEZ a.s.
