摘　　要：由于10 kV配电网结构差异性大,配电线路保护整定值在依据规范的保护整定计算方法基础上,还需要根据具体情况,作一些特殊的考虑,以满足保护可靠性、速动性、选择性、灵敏性的要求。介绍了通过多年实践摸索出的、针对不同电网10 kV配电线路的、综合考虑多种因素实用并可靠的保护整定方法。Because of the huge structure difference among 10 kV distribution network, some special factors should be taken into the protection setting coordination of distribution lines based on standard parameter calculation. The protection setting coordination should comply with the requirements of reliable, quick-response, selective and sensitive protection. Based on practice experience of last many years, a practical and reliable protection coordination method which suits for different kinds of distribution lines is presented.
