Abstract

This paper treats with one of the voltage quality problems when the wind farm is connected with the electrical distribution network and shows the positive effect of wind farms on voltage quality. Variance in voltage and frequency variables determines the quality the electrical grid. In the high and medium voltage grid, the sudden connection and disconnection of the dips. The results show that the connection of the wind farm with medium voltage grid has been increase the network stability and improve the voltage and frequency level for customers and electricity suppliers. During these changes, network stability can be secured through an additional active input. It is important to check whether the wind farm can contribute to improving the state of the network by simulating the system. Due to the change in wind speed, the energy available from the wind farm also vary, which provides volatile variables. This means that the direct connection of the wind farm can lead to network instability In such circumstances, the separation of the variables of the wind farm and the main electric power grid is necessary. The application of power adapters in OTG makes it possible to separate the speed and format of the network frequency format. At the same time, state variables can be controlled independently. This paper provides compensation for voltage reductions by wind farm equipped with power transformers through models based on Matlab-Simulink. Many different sizes of the wind farms are formed and simulated with different nature of loads to get an over-all impression
