First, let me correct a few of your mistakes. The electrical energy generated by the generator is the power value, that is, active power, in kW. The voltage is only 690V at the port of a single fan. Secondly, there is no such thing as series boosting. You have to know that this is a power supply, which can be regarded as a current source or a voltage source. If it is in circuit analysis, then it is true that several voltage sources are connected in series, or current sources are connected together, which can increase the output voltage of the port or the amplitude of the output current (note the amplitude, because the alternating current during AC There is no positive or negative polarity in voltage). But but but!!!! You're confusing circuit analysis with this.
This series connection means that the output lines of a single motor are connected in series (that is, the collector line), not that the motors are connected in series! ! ! !
That is to say, the three-phase outgoing wires on the stator are actually connected in parallel, not in series. You can understand this like this. Look at the picture below and you will understand immediately
First of all, this is the flow direction of the power flow, that is, the flow direction of active power and reactive power. Taking the first group in the picture as an example, the active power is superimposed (added) from the end to the other wind turbines connected in series, and then sent to the wind farm booster station. Suppose your single machine power is 500kW, then the installed capacity of the first group is 4MW. According to the flow direction of the power flow, without considering reactive power, the voltages not only do not add up in sequence (10kV + 10kV), but instead decrease (relatively slightly, because the wind farm power collection lines are short). Therefore, this can actually be understood as a parallel constant voltage source. The parallel voltages are the same, but due to the voltage drop in the impedance value of the collector line, the voltage of the collector line is lower the closer it is to the wind farm booster station. Moreover, you can also think of it this way, the current outside the power supply flows from high potential to low potential, and only when the voltage and the direction of the current are related (what is the correlation, Baidu by yourself), power is emitted (the power supply is emitted power). Finally, finally! ! ! Taking a step back, the most important thing is that even if this voltage is a superposition as you understand it, it is not a superposition of effective values, but a superposition of sinusoidal functions of the voltage.
The conversion rate of wind power is low, the wind speed is unstable, and the energy generated is also unstable
Wind power requires a large amount of land to build wind farms to produce more energy
Wind power When generating electricity, wind turbines will emit huge noise, so it is necessary to find open areas for construction
Wind power generation may interfere with the survival of birds and affect the ecology
Wind power between regions Differently, the large-scale popularization of wind power in areas with low wind power will cause the cost of wind power to be too high, resulting in a waste of resources
