 摘  要
 本文设计了基于电力系统继电保护的微机综合自动重合闸，包括综合重合闸的工作原理、综合重合闸的构成、重合闸与继电保护的配合，装置的硬件部分设计及软件部分设计。并详细介绍了单相自动重合闸，三相自动重合闸，综合自动重合闸，并依据选型针对某110KV线路进行微机综合自动重合闸设计
 重合闸装置有重合闸和选相两个功能，可工作在“单相自动重合闸”、“三相自动重合闸”、“综合自动重合闸”及“停用”四种方式。单相跳闸后，单相重合闸不检查同期，在三相重合闸方式下，有检查同期、检查无压及不检查同期等逻辑。重合闸采用“后加速”方式与继电保护配合。
 微机综合自动重合闸是微机继电保护装置的重要组成部分，自动重合闸与继电保护之间密切良好的配合可以较迅速地切除多数情况下的故障，提高供电可靠性，对系统的安全稳定运行产生极其重要的作用。

Abstract
 In this paper, based on the design of the power system protection of computer integrated automatic reclosing, including integrated reclosing the principle of integrated reclosing the composition, reclosing relay and the co-ordination, installation of hardware and software design part of the design. And details on the single-phase automatic reclosing, the three-phase automatic reclosing, integrated automatic reclosing, and the basis for selection of a 110 KV line to automatically switch on Computer Integrated Design Reclosing installations reclosing and the election of the two functions, can work in the "single-phase automatic reclosing," "three-phase automatic reclosing", "Comprehensive automatically switch on" and "disabled" in four ways. Trip after the single-phase, single-phase reclosing not check the same period, in the three-phase reclosing under way, check the same period, non-pressure check and not check the same period, and so logical. Reclosing of "accelerated after the" manner and relay meet. Computer Integrated Computer automatically reclosing relay device is an important component of the automatic reclosing relay between closely with the good cooperation can be more quickly removed most cases the failure to improve power supply reliability, the system Safe and stable operation to have an extremely important role. Keywords: 110KV lines relay         integrated automatic reclosing
