针对35kV及以下中低压配电网中三段式电流保护动作速度慢、快速保护范围有限的缺点,施慎行所著的《配电线路无通道保护研究》一文提出了利用单端故障分量的快速
Aiming at the shortcomings of three-phase current protection in the low-voltage distribution network of 35kV and below that the speed of the three-phase current protection is slow and the protection range is limited, Shi Shenxing’s article entitled “A Study of Channel-free Protection of Distribution Lines” proposes the use of single-ended fault components. fast
