*5.2. Configuration of Scenario*

In the temporary fault scenario, a single-line ground fault on a-phase occurs in 3.0 s and the recloser on the distribution line trips in 3.1 s. In the case of a temporary fault, the fault lasts for 0.2 s and at 3.2 s the fault is eliminated. Therefore, the islanding operation period is divided into the one during 3.1 s to 3.2 s under fault condition and the other during 3.2 s to 3.6 s when the fault is eliminated. When a fault is cleared and DGs are ready to connect to the system, the recloser recloses in 3.6 s. Figure 9 shows a temporary fault scenario. In this section, the TFRT method in the case of a temporary fault is proved but also, in order to analyze the voltage at the moment of a permanent fault of the control algorithm, we added one scenario for a permanent fault separately from the temporary fault.
