The key depends on the height of the mountain, the wind force on the top of the mountain, and whether the mountain road is gentle. The helicopter is not omnipotent. Sometimes it will be blown away, and sometimes the engine will stall. The power of the helicopter cannot be adjusted to lift things that are too big, and it cannot fly too low on the top of the mountain. . . . So there are many factors to consider. Some may be mountain transport, some may be helicopter transport. . . . Hand beat. . . . .
The 690v alternating current generated by the wind turbine is boosted to 35KV through a single box transformer next to the wind turbine, and then transported to the booster station (wind farm) to be boosted to 220KV, and finally connected to the regional power grid, which is the municipal power grid. level grid. The regulation of power is actually the flow direction of current, similar to the working principle of a battery. Functional power provides energy and flows from high voltage to low voltage. A voltage drop is formed due to the potential difference. In fact, the phase difference is the potential difference in AC. To explain the electrical system, direct current is the potential difference, and alternating current is the phase difference. Reactive power is to supplement the loss of the power grid. Just like the positive electrode of the battery flows to the negative electrode to generate voltage, and the internal battery flows from the negative electrode to the positive electrode to generate electromotive force. The electromotive force and voltage are equal in magnitude and opposite in polarity. The same is true for active power and reactive power, but reactive power and active power are not the same. Equal, polarity is opposite.
