Abstract

This article presents the design of a power system based on flywheel to mitigate voltage sags. With this system the power quality is improved at a point in a distribution network, which is subject to the random connection of electric machines. For this purpose, the power distribution system is modeled, the power supply system which is composed of an electric machine with flywheel, the bidirectional energy conversion system and the current, voltage and speed control system. The designed system enables supplying a power of 22.8 kW and capacity of 1.2 Wh, compensating the transients produced by the loads connected to the network.
