Doubly Fed Induction Generator and Conventional Synchronous Generator Based Power Plants: Operation during Grid Fault
نویسندگان
چکیده
The use of doubly fed induction generator in wind power plants has result in new necessities to maintain a reliable operation of the network. The tendency of the grid codes is to require the ability from the wind power plant to keep connected during and after grid disturbance, similarly to the synchronous generators requirements. This paper analyse the behaviour of a wind power plant equipped with doubly fed induction generators connected to a transmission system during grid fault and compare its performance with a conventional synchronous generator based power plant. The results have shown that the conventional synchronous generator has much more effective injection of reactive power during grid fault and, by consequence, the terminal voltage is kept in higher levels.

The doubly fed induction generator (DFIG) is one of the most popular technologies used in wind power systems. With the growing use of DFIGs and increasing power system dependence on them in recent years, protecting of these generators against internal faults is more considered. Loss of excitation (LOE) event is among the most frequent failures in electric generators. However, LOE detection stud...

In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
