Facts devices in distributed generation

Abstract

The FACTS devices control the interrelated parameters that rule the operation of the transmission systems, including the serial impedance, the derivation impedance, the current, the tension, the phase angle and the muffling of oscillations to different frequencies under the nominal frequency. The FACTS technology has a collection of controllers, that can be used individually or co-ordinated with other controls installed in the network, thus permitting to profit better of the network’s characteristics of control. The configurations of compensators based on switched inverters, called static compensators of reactive power, are today the most used in the electric current transmission systems. The apparition of high-powered electronic converters, makes possible the generation or absorption of reactive power without using banks of condensers or inductors. The STATCOM is a device connected in derivation that can operate in networks of transport as well as of distribution. The functions will depend on the type of network in which it will be installed, it could fulfill functions of reactive power control and tension regulation, or other functions as power factor regulator, shock absorber of system oscillations or filtering of harmonics, depending on the systems applications and the tension level we wish to install.
