As the distributed generation (DG) is connected to the distribution network, the network structure of the original distribution network will change, and the original phase-to-phase (PTP) short circuit (SC) protection strategy will also change. At this time, the protection devices in the transmission line may make some incorrect action instructions, which will lead to the deviation of the coordination between the PTP protection devices in the distribution network and the instability of the system network structure. In order to ensure the reliability of transmission line power supply in distribution network and fully display the potential of DG, it is necessary to study the PTP short-circuit protection. This paper analyzes the influence of(TIO) DG on PTP short-circuit protection in distribution network from three aspects, that is, the influence of DG on PTP short-circuit protection before and after(BAA) access, and TIO DG on the reliability of PTP short-circuit protection. For the access of DG equipment, it changes the distribution of fault current in distribution system and brings transformation effect to the original distribution network protection configuration, so the PTP short-circuit equipment in distribution network will be affected. Finally, the method of combining automatic reclosing with PTP SC protection strategy of distribution network is proposed, so as to protect the safe operation of distribution network system.
