摘  要
 本文設(shè)計(jì)了基于電力系統(tǒng)繼電保護(hù)的微機(jī)綜合自動(dòng)重合閘，包括綜合重合閘的工作原理、綜合重合閘的構(gòu)成、重合閘與繼電保護(hù)的配合，裝置的硬件部分設(shè)計(jì)及軟件部分設(shè)計(jì)。并詳細(xì)介紹了單相自動(dòng)重合閘，三相自動(dòng)重合閘，綜合自動(dòng)重合閘，并依據(jù)選型針對(duì)某110KV線路進(jìn)行微機(jī)綜合自動(dòng)重合閘設(shè)計(jì)
 重合閘裝置有重合閘和選相兩個(gè)功能，可工作在“單相自動(dòng)重合閘”、“三相自動(dòng)重合閘”、“綜合自動(dòng)重合閘”及“停用”四種方式。單相跳閘后，單相重合閘不檢查同期，在三相重合閘方式下，有檢查同期、檢查無壓及不檢查同期等邏輯。重合閘采用“后加速”方式與繼電保護(hù)配合。
 微機(jī)綜合自動(dòng)重合閘是微機(jī)繼電保護(hù)裝置的重要組成部分，自動(dòng)重合閘與繼電保護(hù)之間密切良好的配合可以較迅速地切除多數(shù)情況下的故障，提高供電可靠性，對(duì)系統(tǒng)的安全穩(wěn)定運(yùn)行產(chǎn)生極其重要的作用。

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.
