由于配電(dian)(dian)(dian)(dian)(dian)系統中(zhong)充電(dian)(dian)(dian)(dian)(dian)機負載相(xiang)對(dui)(dui)集(ji)中(zhong)，并且單臺容量(liang)較大(da)，因此采(cai)用(yong)補償方案進行(xing)電(dian)(dian)(dian)(dian)(dian)能(neng)質量(liang)治(zhi)理(li)：在(zai)本地(di)負載端(duan)對(dui)(dui)諧波和無功(gong)電(dian)(dian)(dian)(dian)(dian)流進行(xing)治(zhi)理(li)，避免對(dui)(dui)上一級或更優異配電(dian)(dian)(dian)(dian)(dian)系統造(zao)成影(ying)響。在(zai)鉛酸蓄電(dian)(dian)(dian)(dian)(dian)池的(de)生(sheng)產(chan)過程(cheng)中(zhong)，極板化成環節大(da)量(liang)采(cai)用(yong)三相(xiang)可控硅整流電(dian)(dian)(dian)(dian)(dian)路的(de)充電(dian)(dian)(dian)(dian)(dian)機，在(zai)工作過程(cheng)中(zhong)產(chan)生(sheng)大(da)量(liang)的(de)無功(gong)和諧波，對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)網危害較大(da)。所以，蓄電(dian)(dian)(dian)(dian)(dian)池企(qi)業的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)質量(liang)治(zhi)理(li)已迫在(zai)眉睫。

安裝無功補償元件設(she)計時需要注意的事項(xiang)

此外，由于(yu)工藝需要，必須減少電(dian)(dian)(dian)壓偏(pian)差值(zhi)的，也需要按電(dian)(dian)(dian)壓參(can)數(shu)調節(jie)無功功率。如供電(dian)(dian)(dian)變壓器已(yi)采用自動電(dian)(dian)(dian)壓調節(jie)，則不能再采用以電(dian)(dian)(dian)壓為主參(can)數(shu)的自動無功補償裝置，避免造成(cheng)振蕩。當電(dian)(dian)(dian)容器裝在電(dian)(dian)(dian)動機(ji)控(kong)制設(she)備的負荷側時，流(liu)(liu)過(guo)過(guo)電(dian)(dian)(dian)流(liu)(liu)裝置的電(dian)(dian)(dian)流(liu)(liu)小于(yu)電(dian)(dian)(dian)動機(ji)本身的電(dian)(dian)(dian)流(liu)(liu)，電(dian)(dian)(dian)流(liu)(liu)減少的百分數(shu)近(jin)似(si)值(zhi)可用下式計算：

諧(xie)波的(de)(de)次(ci)(ci)(ci)數(shu)一般(ban)較(jiao)低，以3次(ci)(ci)(ci)和5次(ci)(ci)(ci)為主，無功(gong)補償回路中(zhong)的(de)(de)電抗P值可采取7%的(de)(de)產品(pin)規格(ge)；如果調功(gong)器的(de)(de)晶閘管(guan)采取過(guo)零式(shi)觸發，則諧(xie)波量較(jiao)少，但會出現(xian)分數(shu)次(ci)(ci)(ci)諧(xie)波。此時要用電力儀(yi)表來(lai)檢測諧(xie)波次(ci)(ci)(ci)數(shu)，并做(zuo)好諧(xie)波抑(yi)制(zhi)工作。總之，諧(xie)波治理是(shi)企業的(de)(de)一個大(da)難題，需要采取綜合措施才行。
