Özet:

The operation of wind power plants connected to the grid has been increasing rapidly in recent years. Wind power plants are attractive to use because they both relieve the network and are comparatively economical. However, wind farms are affected by the problems that may occur during their operation depending on the network. These problems are especially seen as voltage drop and increased oscillations. Dynamic modelling and control of the wind farm gains importance against these problems. Among the most important reasons for using DFIG in turbine systems are high energy yield, reduction of mechanical loads, applicability of easier angle control system, wide control of active and reactive power, and fluctuations in output power. In this study, power control results of DFIG based wind energy system by using OPAL-RT technology are given and real time control simulation is performed. Real time results have shown that when the Id current is changed in the system, active power decreases to balance the total while the reactive power increases.
