1 概述

科(ke)學技術為人們的(de)(de)(de)(de)生產生活(huo)帶來了極(ji)大的(de)(de)(de)(de)便(bian)利，電力系(xi)統(tong)(tong)隨(sui)著(zhu)用戶(hu)要求(qiu)的(de)(de)(de)(de)增長不斷的(de)(de)(de)(de)發(fa)展(zhan)(zhan)提高(gao)，并(bing)且(qie)隨(sui)著(zhu)用戶(hu)自動(dong)化要求(qiu)的(de)(de)(de)(de)提高(gao)，對于(yu)電源電壓更是要求(qiu)越來越高(gao)，以(yi)此保證電力系(xi)統(tong)(tong)的(de)(de)(de)(de)穩(wen)定。局(ju)部(bu)電網(wang)由(you)于(yu)發(fa)展(zhan)(zhan)程度有限(xian)，其會受(shou)到(dao)動(dong)性(xing)負荷的(de)(de)(de)(de)影響從(cong)而(er)導(dao)致電壓波(bo)動(dong)，或者(zhe)功率因數(shu)惡化，當電網(wang)出現該(gai)種現象后，會極(ji)大的(de)(de)(de)(de)影響自動(dong)化電氣設備的(de)(de)(de)(de)壽命(ming)，并(bing)且(qie)自動(dong)化越高(gao)受(shou)到(dao)影響越大，從(cong)而(er)間接性(xing)阻礙(ai)了企業(ye)的(de)(de)(de)(de)發(fa)展(zhan)(zhan)。所以(yi)，電力補償系(xi)統(tong)(tong)能夠(gou)對系(xi)統(tong)(tong)功率因數(shu)進(jin)行改善，穩(wen)定系(xi)統(tong)(tong)電壓，這成(cheng)為了電力系(xi)統(tong)(tong)研究的(de)(de)(de)(de)必然趨勢。

電(dian)(dian)容(rong)器并聯到(dao)配電(dian)(dian)線路(lu)(lu)中(zhong)能夠有(you)效對(dui)電(dian)(dian)壓(ya)分布予以改(gai)善，且(qie)能夠有(you)效減少(shao)線路(lu)(lu)損耗，增加(jia)線路(lu)(lu)負荷的(de)輸出能力，提高(gao)線路(lu)(lu)的(de)功(gong)率因數(shu)，這(zhe)種方式操(cao)作簡便(bian)可(ke)行性(xing)較(jiao)(jiao)(jiao)高(gao)，所以在(zai)(zai)電(dian)(dian)力系統(tong)中(zhong)得到(dao)了廣泛應用。為(wei)了提高(gao)波動性(xing)負荷的(de)適(shi)應性(xing)，對(dui)補(bu)償容(rong)量(liang)的(de)調節可(ke)以通過(guo)電(dian)(dian)容(rong)器的(de)分組投切的(de)方式，靜(jing)止(zhi)補(bu)償器是電(dian)(dian)容(rong)器中(zhong)相(xiang)應速度較(jiao)(jiao)(jiao)快的(de)且(qie)不會(hui)產(chan)生機械磨損的(de)部件，但是TSC的(de)控(kong)制系統(tong)較(jiao)(jiao)(jiao)為(wei)復雜(za)，應用在(zai)(zai)高(gao)壓(ya)系統(tong)中(zhong)的(de)晶(jing)匣管，其并聯技術(shu)不易實現隔離出發，這(zhe)樣不但無法保證系統(tong)的(de)安全性(xing)，并且(qie)成本過(guo)高(gao)。

考(kao)慮到上(shang)(shang)述問題，對(dui)配電(dian)系統(tong)的(de)負荷波動慢(man)的(de)可以通過(guo)并聯電(dian)容器(qi)組投入真空接觸器(qi)提高設(she)備的(de)性(xing)能，該種(zhong)接觸器(qi)在控制上(shang)(shang)更(geng)為(wei)便捷，能夠(gou)多(duo)次頻繁操作，并且不需(xu)要對(dui)滅(mie)弧室(shi)進(jin)行(xing)檢修。文章中介紹的(de)自行(xing)研制的(de)10kV無功補償(chang)是采(cai)用的(de)接觸器(qi)對(dui)電(dian)容器(qi)組進(jin)行(xing)投切(qie)，從實際的(de)操作中可以看(kan)出(chu)，該種(zhong)系統(tong)不但具有簡單的(de)系統(tong)結構，同時性(xing)能以及成本投入上(shang)(shang)都具有極高的(de)價值，且其(qi)補償(chang)效果較之其(qi)他方(fang)式(shi)也十分突出(chu)，因此應用前景極其(qi)廣闊。

2.1 主回路

針(zhen)對該補償系統，在(zai)(zai)運(yun)行(xing)(xing)(xing)過程中(zhong)會(hui)出現電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)故障或(huo)者相間短路(lu)，因(yin)此為(wei)(wei)(wei)避(bi)免(mian)該種(zhong)現象以(yi)及(ji)在(zai)(zai)出現單相接(jie)地(di)故障后(hou)系統的(de)(de)(de)對地(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，系統電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)(qi)組(zu)往(wang)往(wang)采用單Y型接(jie)線(xian)方(fang)式(shi)(shi)，以(yi)該種(zhong)不(bu)接(jie)地(di)的(de)(de)(de)中(zhong)性點接(jie)線(xian)方(fang)式(shi)(shi)避(bi)免(mian)上述(shu)問(wen)題(ti)的(de)(de)(de)發(fa)生。但(dan)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)(qi)在(zai)(zai)合閘時(shi)會(hui)出現涌流(liu)并且還會(hui)對諧波(bo)(bo)(bo)進(jin)(jin)行(xing)(xing)(xing)放(fang)大(da)，為(wei)(wei)(wei)避(bi)免(mian)該種(zhong)現象的(de)(de)(de)發(fa)生，可(ke)以(yi)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)回路(lu)上串聯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)(qi)(qi)(qi)(qi)進(jin)(jin)行(xing)(xing)(xing)改善。但(dan)是必(bi)須要注意我(wo)國目前在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)回路(lu)中(zhong)串聯的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)(qi)(qi)(qi)(qi)，一般其(qi)感抗(kang)(kang)值(zhi)為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)容(rong)(rong)抗(kang)(kang)值(zhi)的(de)(de)(de)4.5%至6%之間或(huo)者12%至13%之間，如(ru)此一來，就會(hui)造成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)(qi)在(zai)(zai)運(yun)行(xing)(xing)(xing)時(shi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓被(bei)提高(gao)，那么(me)過壓就會(hui)在(zai)(zai)分閘時(shi)產生，因(yin)而一些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)(qi)組(zu)在(zai)(zai)投(tou)(tou)入運(yun)行(xing)(xing)(xing)后(hou)效率(lv)不(bu)高(gao)，有(you)些(xie)甚至是在(zai)(zai)某些(xie)情況(kuang)下無法(fa)投(tou)(tou)運(yun)。針(zhen)對此類問(wen)題(ti)，可(ke)以(yi)在(zai)(zai)設備中(zhong)安裝(zhuang)具(ju)有(you)濾(lv)(lv)波(bo)(bo)(bo)功能(neng)的(de)(de)(de)裝(zhuang)置，但(dan)是濾(lv)(lv)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)加(jia)入肯定會(hui)加(jia)大(da)投(tou)(tou)資(zi)，提高(gao)了(le)(le)(le)設備的(de)(de)(de)成本。針(zhen)對該種(zhong)問(wen)題(ti)，不(bu)一定必(bi)須加(jia)裝(zhuang)濾(lv)(lv)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)(qi)，在(zai)(zai)進(jin)(jin)行(xing)(xing)(xing)并聯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)組(zu)安裝(zhuang)前，首先對安裝(zhuang)的(de)(de)(de)現場諧波(bo)(bo)(bo)情況(kuang)進(jin)(jin)行(xing)(xing)(xing)研究了(le)(le)(le)解，只需要保(bao)證電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)(qi)諧波(bo)(bo)(bo)頻(pin)率(lv)以(yi)及(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)諧波(bo)(bo)(bo)頻(pin)率(lv)比最低次諧波(bo)(bo)(bo)小便可(ke)，如(ru)此一來就有(you)效控(kong)制了(le)(le)(le)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)值(zhi)。因(yin)此針(zhen)對該系統，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)值(zhi)只需要為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)(qi)(qi)(qi)容(rong)(rong)抗(kang)(kang)的(de)(de)(de)百分之一便可(ke)。此外，串聯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)(qi)(qi)(qi)(qi)大(da)多適用干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)(qi)(qi)(qi)(qi)，這種(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)(kang)器(qi)(qi)(qi)(qi)(qi)(qi)具(ju)有(you)較強的(de)(de)(de)機械強度，并且噪(zao)音低，無需過大(da)的(de)(de)(de)維護量。

2.2 對回路(lu)有效保(bao)護

系(xi)統可以(yi)頻(pin)繁操作(zuo)，不需要頻(pin)繁的檢修(xiu)滅弧室，不會(hui)(hui)發生(sheng)少油斷路器(qi)(qi)出油故(gu)障(zhang)等，這些都是真空接觸(chu)器(qi)(qi)所具有(you)的優點，但是在斷開真空接觸(chu)器(qi)(qi)后(hou)會(hui)(hui)發生(sheng)重燃故(gu)障(zhang)，從(cong)而產生(sheng)操作(zuo)過(guo)(guo)電(dian)壓，引(yin)發一些系(xi)統故(gu)障(zhang)。針對該類問題，可以(yi)通(tong)過(guo)(guo)加裝(zhuang)避(bi)雷器(qi)(qi)予以(yi)消除，本系(xi)統所使(shi)用的避(bi)雷器(qi)(qi)為氧化(hua)鋅避(bi)雷器(qi)(qi)，主要用以(yi)保(bao)護(hu)(hu)電(dian)容器(qi)(qi)。需要注意的是，在中(zhong)性點對地加設避(bi)雷器(qi)(qi)能夠有(you)效對重燃過(guo)(guo)電(dian)壓進行限制，并且氧化(hua)鋅避(bi)雷器(qi)(qi)在保(bao)護(hu)(hu)系(xi)統的過(guo)(guo)程中(zhong)不會(hui)(hui)承(cheng)受電(dian)壓。

放電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)并(bing)聯在(zai)系(xi)統(tong)中(zhong)能夠(gou)將(jiang)電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)產(chan)生(sheng)(sheng)的(de)(de)(de)剩(sheng)余(yu)電(dian)(dian)(dian)(dian)荷(he)及(ji)時有(you)效的(de)(de)(de)釋放掉，并(bing)對電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)產(chan)生(sheng)(sheng)的(de)(de)(de)涌流作(zuo)(zuo)第二(er)次的(de)(de)(de)降(jiang)低，以此(ci)預防由于電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)過流而(er)發生(sheng)(sheng)設備爆炸，保(bao)證了(le)操作(zuo)(zuo)人員的(de)(de)(de)生(sheng)(sheng)命(ming)安(an)全。在(zai)此(ci)基礎(chu)上放電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)還具有(you)繼電(dian)(dian)(dian)(dian)保(bao)護(hu)功能以及(ji)測量功能，放電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)能夠(gou)形成(cheng)保(bao)護(hu)電(dian)(dian)(dian)(dian)路，這(zhe)是其(qi)巨大優勢，當電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)組在(zai)星型接線(xian)(xian)(xian)內發生(sheng)(sheng)故(gu)障時，即便(bian)只(zhi)是其(qi)中(zhong)一(yi)臺出現(xian)了(le)故(gu)障，那么在(zai)中(zhong)性點處就會產(chan)生(sheng)(sheng)位移(yi)電(dian)(dian)(dian)(dian)壓(ya)，若是該處產(chan)生(sheng)(sheng)了(le)過高的(de)(de)(de)位移(yi)電(dian)(dian)(dian)(dian)壓(ya)，則(ze)有(you)可能會產(chan)生(sheng)(sheng)一(yi)個跳(tiao)閘動(dong)作(zuo)(zuo)的(de)(de)(de)命(ming)令(ling)信(xin)號，將(jiang)該組電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)從電(dian)(dian)(dian)(dian)路系(xi)統(tong)中(zhong)切除出去。

此外，只針對負荷(he)電(dian)(dian)(dian)流進行切斷(duan)，對于線路(lu)中的(de)短路(lu)電(dian)(dian)(dian)流不產生作(zuo)用(yong)，系(xi)(xi)統(tong)(tong)(tong)還(huan)在(zai)每臺電(dian)(dian)(dian)容器(qi)前加裝(zhuang)了(le)噴逐(zhu)式熔斷(duan)器(qi)，用(yong)以避免過(guo)流現(xian)象對系(xi)(xi)統(tong)(tong)(tong)電(dian)(dian)(dian)路(lu)的(de)損(sun)壞。同時(shi)，系(xi)(xi)統(tong)(tong)(tong)還(huan)為過(guo)壓以及(ji)欠壓現(xian)象的(de)出現(xian)做了(le)預先的(de)系(xi)(xi)統(tong)(tong)(tong)保護(hu)措施，并且(qie)還(huan)具有拒動閉鎖功能(neng)，用(yong)以提高系(xi)(xi)統(tong)(tong)(tong)的(de)自(zi)我保護(hu)能(neng)力，使得設備(bei)運行的(de)可(ke)靠(kao)性有效提升(sheng)。
