The 690V alternating current generated by the wind turbine is increased to 35KV via a single box transformer located next to the wind turbine, and then transported to the booster station (wind farm) to be increased to 220 KV and finally connected to the regional network. electrical network, which is the municipal electrical network. Power regulation is actually the direction of current flow, similar to the operating principle of a battery. Functional power provides energy and changes from high voltage to low voltage. A voltage drop forms due to the potential difference. The difference is the alternating current potential difference. To explain the electrical system, direct current is the potential difference and alternating current is the phase difference. Reactive power is used to supplement losses from the electricity network. Just like the positive electrode of the battery flows towards the negative electrode to generate a tension, and the internal flow of the battery from the negative electrode to the positive electrode generates the electromotive force. force and voltage are equal in magnitude and opposite in polarity. The same goes for active power and reactive power, but reactive power and active power are not equal, the polarity is opposite.
Conditions for connecting wind turbines to the network and doubts about the direction of transport

Introduction There are doubts about the conditions of connection to the wind turbine network and the direction of transmission. The 690 V alternating current generated by the wind turbine is increased to 35 KV by a single box transformer located next to the wind turbi
