Non-communication protection method for meshed and radial distribution networks with synchronous-based DG

Fuse saving scheme in highly photovoltaic‐integrated distribution networks

“…V recl,F is locally measured using the potential transformer installed at the main substation. –The exponential function prevents the operating time of recloser reduces to zero when a fault occurs at the beginning of the feeder. In Jamali and Borhani‐Bahabadi, due to use of V recl,F in the numerator of modification term, the recloser operating time is zero for the zero voltage condition, as shown in Table . –Since the modified operating time of recloser should be proportional to the voltage drop at the beginning of feeder, the recloser should operate fast for the faults occurred near its location due to significant voltage drop while in the case of a fault far from the recloser location, its operating time increases. To satisfy this principle, the term of 1− V recl,F should be included in the exponential function of modification term.…”

“…The study results are shown in Table . OCBMT strategy enhances the performance of current‐based modification term proposed in Shah and Bhalja while OVBMT strategy enhances the performance of voltage‐based modification terms proposed in Saleh et al and Jamali and Borhani‐Bahabadi . In comparison with Shah and Bhalja, OCBMT strategy allows for more PV sources without protection miscoordination.…”

“…Borhani-Bahabadi. [29][30][31] This group reduces the operating time of the fast operation curve of the recloser using a voltage term. Similar to the previous group, this method requires the microprocessor-based reclosers.…”

[29][30][31] In comparison with Shah and Bhalja, 27 OCBMT strategy allows for more PV sources without protection miscoordination. Also, OVBMT strategy provides the possibility of installing more PV sources compared with Saleh et al 28 and Jamali and Borhani-Bahabadi [29][30][31] with preserving the coordination between fuse and recloser in the worst case of DN short-circuit fault and maximum PL of PV systems.…”

It verifies that the proposed scheme facilitates the integration of higher PL of PV units into DN.…”
