110kv電網(wǎng)繼電保護(hù)設(shè)計(jì)摘要

1、XX大學(xué)電力學(xué)畢業(yè)設(shè)計(jì)摘要本次設(shè)計(jì)是110KV電網(wǎng)線路上的繼電保護(hù)。系統(tǒng)由四個(gè)發(fā)電廠和五個(gè)變電站分別構(gòu)成輻射形多電源環(huán)形網(wǎng)絡(luò)。主要對LBBD1、LABD5線路進(jìn)行相間繼電保護(hù)方式、零序繼電保護(hù)方式的選擇與整定計(jì)算。本次設(shè)計(jì)成果分為兩部分，即：說明書與計(jì)算書。說明書主要是對整定計(jì)算過程的原理、原則及計(jì)算結(jié)果表進(jìn)行說明總結(jié)。設(shè)計(jì)內(nèi)容包括：電氣參數(shù)數(shù)據(jù)的分析整定，TV、TA變比的選擇，中性點(diǎn)接地的確定，電力網(wǎng)短路電流的計(jì)算，電力網(wǎng)相間繼電保護(hù)

2、配置及整定計(jì)算（LB─BD1、LA─BD5），電力網(wǎng)零序繼電保護(hù)配置及整定計(jì)算（LB─BD1、LA─BD5），自動(dòng)重合閘的選擇七個(gè)部分。計(jì)算書主要是對設(shè)計(jì)中的參數(shù)、短路電流及保護(hù)的整定值進(jìn)行計(jì)算。計(jì)算內(nèi)容包括：電力系統(tǒng)各元件主要參數(shù)的計(jì)算；電力網(wǎng)短路電流的計(jì)算；相間距離保護(hù)的整定計(jì)算；零序電流的整定計(jì)算。關(guān)鍵字：繼電保護(hù)短路電流計(jì)算相間繼電保護(hù)零序繼電保護(hù)XX大學(xué)電力學(xué)畢業(yè)設(shè)計(jì)SummaryThedesignisprotectionon
