Power distribution network airborne line fault simulation experiment system

The invention discloses a power distribution network airborne line fault simulation experiment system, which comprises a full compensation control module, a self-adaptive zero sequence admittance measurement module and a PWM (Pulse Width Modulation) controlled processing chip. The full compensation control module uses a compensation mode combining pre-modulation and random modulation, and the interior of the full-compensation control module is divided into a normal state unit and a fault response unit. The self-adaptive zero sequence admittance measurement module adopts a difference algorithm, and the PWM-controlled processing chip is used for controlling a power device of a slave arc suppression coil inverter. According to the airborne line fault simulation experiment system for the power distribution network, on the basis of analyzing grounding fault characteristics, a technology capable of carrying out full compensation on grounding fault current is researched and developed; a reverse current is injected i
