摘要
针对较短线路与上级线路灵敏度配合难点,合理将短线的上级线路中最长线路及短线的下级变压器阻抗引入整定范围,并且通过表格的组织,提高了对批量线路的整定效率,以某地区电网终端短线路距离保护整定计算方案及相关配合问题作探讨。
Based on short circuit with the superior circuit sensitivity with difficulty, reasonable to short - term superior line short circuit and the longest of the lower transformer impedance setting range are introduced, and through the form of organization, to improve the efficiency of the mass line setting. And in this paper, the Calculation Scheme and Cooperative scheme for distance protection of short terminal power line in a certain area is discussed.
