Abstract

Doubly fed induction generator (DFIG) has a vital role in wind turbines and their use is growing. The benefits are separate control reactive power, no need to compensator of reactive power, ability to function in a wide range of speed and having a small power electronic converters with capable of processing all generators active and reactive power. During an error in the network, to prevent the damages caused by passing high currents, converter cut the rotor-side in the DFIG. At this time, network-side converter loses its ability to supply the required reactive power and thus voltage stable and confirmation get in danger. In order to overcome this problem, benefices by using equipment's, such as STATCOM or SVC, provides the reactive power needs and embargo of cutting the wind farms from the network. Thus, the injection continuation of DFIG active power production will be established. Power electronic converters that usually used in the equipment structures of, STATCOM, SVC or even rotor-side converter and network in DFIG, often are voltage source inverters.  This article theory is whether structure and capacity of the converter in DFIG is designed so that during causes error can enter the circuit as a STATCOM and take the charge of needed reactive power generation. Avoid the use of two transducers individually and by designing a converter with enough capacity, two types can be used, thus costs losses.
