摘要
本文根据当代城市及大型企业中配电网络的特点和供电要求,提出了配电线路故障全线速切的概念,分析了其必要性和可行性,提出了实用的实施方案,与常规的时限配合式保护进行了综合经济技术比较。
A new concept of whole line fault high speed clearing protection is introduced according to the structure of urban distribution power system and requirement of power supplying.Feasibility study on this protection is carried out.A practical implement scheme of this protection,which measures the electrical signal on both sides of the protected line is presented.
