1 This is the main wiring diagram of a wind power plant in Northeast China. The so-called wind type 2 A at the bottom is the incoming line of a wind generator, which is sent to the 10KV bus, and adopts a 10KV draw-out switchgear, in which the red square is 10KV circuit breaker with isolating plugs on both sides. This power distribution device 10KV is divided into two sections, and different fans are connected to the two sections respectively, and then the voltage is raised to 66KV through a step-up transformer. * * * There are two transformers. The transformer 10KV side is still a draw-out switchgear, and the 66KV side is connected to the 66KV bus through the switch (red side) disconnector (with cross arrow). These circuit breakers are used to open the circuit, and the disconnector next to the circuit breaker is used to completely open the circuit after the circuit breaker is opened.

The following table shows various parameters sent by the fan, including active power and reactive power. The so-called reverse direction means that it is possible that the wind turbine needs to send electricity from the system in the reverse direction, which is relatively rare.
