        What is the principle of Yuchai generator excitation current regulation? Let's find out with you here:
        In changing the excitation current of the Yuchai generator, it is generally not carried out directly in its rotor circuit, because the current in this circuit is very large, which is not convenient for direct adjustment. The usual method is to change the excitation current of the exciter to achieve adjustment. The purpose of the generator rotor current.
        Commonly used methods include changing the resistance of the excitation circuit of the exciter, changing the additional excitation current of the exciter, and changing the conduction angle of the thyristor. Here we mainly talk about the method of changing the conduction angle of the thyristor. It changes the conduction angle of the thyristor rectifier accordingly according to the change of the voltage, current or power factor of the generator, so the excitation current of the Yuchai generator changes accordingly. .
        This device is generally composed of transistors and thyristor electronic components, and has the advantages of sensitivity, speed, no failure zone, large output power, small size and light weight. In the event of an accident, it can effectively suppress the overvoltage of the generator and achieve rapid de-excitation.

        The above is the principle of Yuchai generator excitation current regulation.
