1）anapf有源電力濾(lv)波器 

1.)工作原理(li) 

    anapf系列有源電(dian)(dian)(dian)力(li)濾波(bo)(bo)(bo)器(qi)并(bing)(bing)聯(lian)在含諧(xie)波(bo)(bo)(bo)負載(zai)的(de)低壓(ya)配電(dian)(dian)(dian)系統中，能夠對動態變化的(de)諧(xie)波(bo)(bo)(bo)電(dian)(dian)(dian)流(liu)進行快(kuai)速實時(shi)的(de)跟蹤(zong)和(he)補(bu)償。其原理(li)為：anapf系列有源電(dian)(dian)(dian)力(li)濾波(bo)(bo)(bo)器(qi)通(tong)過ct采集系統諧(xie)波(bo)(bo)(bo)電(dian)(dian)(dian)流(liu)，經(jing)控制器(qi)快(kuai)速計算并(bing)(bing)提(ti)取各次諧(xie)波(bo)(bo)(bo)電(dian)(dian)(dian)流(liu)的(de)含量，產生諧(xie)波(bo)(bo)(bo)電(dian)(dian)(dian)流(liu)指令，通(tong)過功率執行器(qi)件(jian)產生與諧(xie)波(bo)(bo)(bo)電(dian)(dian)(dian)流(liu)幅值相等方向相反的(de)補(bu)償電(dian)(dian)(dian)流(liu)，并(bing)(bing)注入電(dian)(dian)(dian)力(li)系統中，從(cong)而抵消非線性負載(zai)所產生的(de)諧(xie)波(bo)(bo)(bo)電(dian)(dian)(dian)流(liu)。 

2）ansvc低(di)壓(ya)無功(gong)(gong)功(gong)(gong)率補(bu)償(chang)裝置 

2.1）工作原理 

  ansvc低壓無(wu)功功率(lv)(lv)補償(chang)裝置并聯在(zai)整(zheng)個供電(dian)(dian)(dian)(dian)系統中，能根據(ju)電(dian)(dian)(dian)(dian)網中負載功率(lv)(lv)因數(shu)的變化控制電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)容(rong)器(qi)投切(qie)進行(xing)補償(chang)。其(qi)原(yuan)理為：ansvc低壓無(wu)功功率(lv)(lv)補償(chang)裝置通(tong)過ct采集電(dian)(dian)(dian)(dian)流、電(dian)(dian)(dian)(dian)壓信號，通(tong)過無(wu)功補償(chang)控制器(qi)計算，計算出(chu)投切(qie)電(dian)(dian)(dian)(dian)容(rong)器(qi)的好方案，通(tong)過無(wu)觸(chu)點開(kai)關控制各組(zu)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)容(rong)器(qi)投切(qie)。
