Especially the microprocessor came out in 1970s , the improvement and application of microcomputer have been accelerating to much extent , which cause revolution of new technology in the world and give a impetus to the development of information age 特别是自70年代初以来,微处理器的问世促使微型计算机技术迅速发展和应用,在世界范围内引起了一场新的革命,并推动人类进入到信息时代。
The precise location of high - voltage transmission line fault is of great significance and practical engineering value . for years , general importance has been attached to the study of faults location by the network operation and management departsments and specialists . but owing to the short developmengt history of faults location techniques and the limits of related techniques , fault location devices with high precision are not widely used in practice . with the development of computer communication technology and the wide application of microcomputer - based protection devices with electric power system , it is possible to locate high - voltage transmission line faults precisely 多年以来,故障测距问题的研究一直受到电网运行、管理部门和专家学者的普遍重视。但由于故障测距技术本身发展的历史并不长和相关技术条件的限制,具有较高精度的故障测距装置在实际中的应用并不多。随着计算机通信技术的发展和微机保护装置在电力系统中的广泛应用,实现高压输电线路故障的准确定位已经成为可能。
