摘要: This paper presents an adaptive protection scheme for distribution networks with distributed generation. The proposed system offers the novelty of being able to both locate zone in which fault has occurred and adapt setting parameters relays involved process each network condition. unified can be applied detection main feeder lateral branches, taking into account variable conditions power generation demand. relays' responsible coordination is done by optimizing three degrees freedom using mixed-integer nonlinear optimization techniques. validated a standard test prove its capability faults branches optimize performance under conditions, different types locations. reduces relay operating time significantly compared classical linear
