2.1設(shè)計(jì)解決方案
很長(zhǎng)時(shí)間以來(lái),變電站繼電保護(hù)交直流串?dāng)_問(wèn)題就一直存在于變電站中,并且直觀地說(shuō),我們并沒(méi)有一個(gè)能夠完美解決它的辦法,大多數(shù)時(shí)候在實(shí)際操作時(shí),為了避免事故的時(shí)常發(fā)生,會(huì)安排經(jīng)驗(yàn)豐富的工作人員去負(fù)責(zé)這一塊的工作,但是這樣的做法并不能完全使得事故不再發(fā)生,因此也不是可靠的選擇。本文的觀點(diǎn)是將直流電源不可替代的作用發(fā)揮出來(lái),用它替代交流電源來(lái)作為繼電保護(hù)電源,下面是本文作者想出來(lái)的兩種方案。
2.1.1將驅(qū)動(dòng)設(shè)備進(jìn)行更換。更換驅(qū)動(dòng)設(shè)備,即將交流的設(shè)備更換為直流的,交直流電源串?dāng)_問(wèn)題的主要原因是直流與交流同時(shí)存在而引起的,因此如果將交流設(shè)備都換成直流的設(shè)備,可以很有效的解決串?dāng)_問(wèn)題,但是在另一方面,直流設(shè)備在市場(chǎng)上的流量很小,因此購(gòu)買(mǎi)變得異常困難,并且因?yàn)闆](méi)有較大的交易量,因此這種專業(yè)上的人員特別少,造成維修的困難與昂貴;還有就是如果直流設(shè)備直接接入直流電源直流系統(tǒng),會(huì)使得直流接地的情況發(fā)生的更為頻繁,因此在這方面要多加注意。
