Flexible switching control method for boost resistance-capacitance branch of high-voltage fault generating device

According to the flexible switching control method for the boost resistance-capacitance branch circuit of the high-voltage fault generation device, the opening and closing operation of a short-circuit switch is controlled in a split-phase manner, and the flexible switching control of the boost resistance-capacitance branch circuit of the high-voltage fault simulation device is realized. A boost resistance-capacitance branch flexible switching control module is arranged, the boost resistance-capacitance branch flexible switching control module detects a voltage difference value between line voltages of two phases of a PCC point and line voltages of corresponding two phases of boost capacitors in real time, and when the absolute value of the line voltage difference value meets a voltage difference threshold value, the corresponding short circuit switches are controlled to be switched on in a split-phase mode, and the corresponding short circuit switches are switched off in a split-phase mode.
