Electrical network simulation for increasing quality

The simulation is one of the most important components of engineering from our days. To have a complete view of an entire electrical network it is absolutely necessary to use software. Using software you can tackle the correct decision of what to do in the network. Using a simulation it is not necessary to do changes in real network to obtain results of those changes. Also is very important the quality of electrical energy transported on the network. The purpose of this paper is to show some result concerning the quality of electrical energy in real networks.
