**4. Temporary Fault Ride-Through Method**

Temporary fault most commonly occurs in distribution systems, and is eliminated before the first reclosing of the recloser. However, due to recloser opening, the anti-islanding function of DG is triggered, and all DGs are disconnected. Therefore, this paper proposes a control method to prevent unnecessary disconnection of DG in the case of a temporary fault. This method is defined as the Temporary Fault Ride-Through (TFRT), and consists of two controllers—Low/High Voltage Ride Through (L/HVRT) and Inrush Current Suppressing controller. The former suppresses over/under-voltages during temporary fault and the latter inrush current due to voltage amplitude and phase di fference between both sides of a CB or recloser at their reclosing time. This control is described below.
