【摘要】：近年來(lái),世界范圍內(nèi)的大規(guī)模停電事故時(shí)有發(fā)生,造成了巨大的經(jīng)濟(jì)損失和嚴(yán)重的社會(huì)影響。大停電發(fā)生后,制定切實(shí)可行的黑啟動(dòng)恢復(fù)方案,采用有效恢復(fù)措施進(jìn)行系統(tǒng)的快速恢復(fù),尤其對(duì)局部孤立系統(tǒng)進(jìn)行黑啟動(dòng)自救,對(duì)減少事故帶來(lái)的經(jīng)濟(jì)損失和社會(huì)動(dòng)蕩具有重要意義。河北南部電網(wǎng)是華北電網(wǎng)的重要組成部分,是西電東送、南北互供的重要通道,對(duì)其大停電后的恢復(fù)方案進(jìn)行研究非常必要。本文研究以相鄰?fù)獠侩娋W(wǎng)作為黑啟動(dòng)電源的河北南網(wǎng)黑啟動(dòng)恢復(fù)方案,針對(duì)外網(wǎng)電源位置,對(duì)河北南網(wǎng)進(jìn)行合理分區(qū),形成多個(gè)子系統(tǒng)并行恢復(fù)的黑啟動(dòng)方案。研究各個(gè)子系統(tǒng)內(nèi)網(wǎng)架重構(gòu)方案和各個(gè)分區(qū)子系統(tǒng)網(wǎng)架恢復(fù)后的并網(wǎng)方案,對(duì)并網(wǎng)時(shí)間和并網(wǎng)點(diǎn)進(jìn)行計(jì)算校核�；诤颖蹦暇W(wǎng)實(shí)際數(shù)據(jù)的相關(guān)計(jì)算校驗(yàn)結(jié)果驗(yàn)證了本文提出的系統(tǒng)分區(qū)方案和區(qū)內(nèi)恢復(fù)策略的正確性和有效性,通過(guò)將河北南網(wǎng)分為保定、石家莊、邢邯、衡滄四個(gè)分區(qū),制定科學(xué)合理的電網(wǎng)黑啟動(dòng)恢復(fù)方案并制定相關(guān)的實(shí)施要求,為實(shí)現(xiàn)整個(gè)系統(tǒng)的快速恢復(fù)提供決策支持,可有效地減小事故帶來(lái)的經(jīng)濟(jì)損失和社會(huì)影響。
[Abstract]:In recent years, worldwide large-scale power outages have occurred from time to time, resulting in huge economic losses and serious social impact. After the blackout occurred, the feasible black start recovery scheme was established, and the effective recovery measures were adopted to carry out the rapid recovery of the system, especially for the local isolated system to carry out the black start self-rescue. It is of great significance to reduce the economic loss and social unrest caused by the accident. Southern Hebei Power Grid is an important part of North China Power Grid, it is an important channel for power supply from west to east, and from north to south. It is very necessary to study the recovery scheme after power outages. In this paper, the black-start recovery scheme of Hebei Southern Power Network with adjacent external power grid as black-start power supply is studied. According to the location of power supply in the outer network, a reasonable partition is made to form a black-start scheme for parallel restoration of several subsystems. The reconfiguration scheme of each sub-system and the scheme of grid connection after the restoration of each sub-system are studied, and the time and points of grid connection are calculated and checked. The validity and validity of the proposed system zoning scheme and regional recovery strategy are verified by the relevant calculation and verification results based on the actual data of Hebei South Network. By dividing the South Hebei Network into four zones, Baoding, Shijiazhuang, Xing Han and Hengcang, It can effectively reduce the economic loss and social impact brought by accident by making a scientific and reasonable scheme of black-start restoration of power grid and relevant implementation requirements to provide decision support for the rapid recovery of the whole system.
