摘要
根据电流保护选择性和灵敏性的矛盾，利用微机保护的特点，提出了线路电流保护的在线整定技术，在相同保护范围和选择性的基础上可以大大提高保护的灵敏度系数。不仅使得电流保护具有一定的自适应性，而且实现技术简单可靠，具有较大的实用价值。
According to the contradiction between the selectivity and the sensitivity with current protection, the on_line setting technology based on the micro_computer relays is presented in this paper. The sensitivity is obviously improved for the same protecting zone by this technology. It is not only self_adaptive for current relaying protection on different operation modes, but also simple and reliable. It has practical values.
