摘　　要：详细介绍了电力系统智能型接地距离保护整定计算程序的计算数学模型和程序的主要功能及智能化特点 ,分析了线路零序互感对保护整定计算的影响 ,研制出解决这一影响的实用优化的整定原则 ,该程序不仅能完成接地距离保护各段定值及相关参数的整定计算 ,而且能输出汉化整定方案、全网定值表及定值通知单 ,实现对接地距离微机智能管理。In this paper, the mathematics module, main functions and intelligent feature are presented for the intelligent setting computing program of the electric power system. The influence of line mutual inductance of zero sequence on setting computing is analyzed. The practical optimized principle is presented to solve this influence. The setting value of three sections and relative parameters of earthing distance protection can be printed in Chinese character. Furthermore, the setting value table of the whole system and a requisition can also be printed to accomplish intelligent computer management of earthing distance protection.
