隨著電力電子(zi)技(ji)術，特別是大(da)功(gong)(gong)(gong)率(lv)(lv)可關斷器件技(ji)術的發展和日益完善，國內外還在研制、開發一種更(geng)為先進的靜止無功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)發生裝置(SVG)，SVG憑借著其優(you)越的性能(neng)特點，在電力系統中(zhong)的應用(yong)將越來越廣泛(fan)。電網輸出的功(gong)(gong)(gong)率(lv)(lv)包括兩(liang)部分(fen)：有功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)和無功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)。有功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)是指(zhi)直接消耗電能(neng)，把電能(neng)轉(zhuan)變(bian)(bian)為機(ji)械能(neng)、熱能(neng)或化學能(neng)，利用(yong)這部分(fen)能(neng)量作(zuo)功(gong)(gong)(gong)。而無功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)則是指(zhi)為建立交變(bian)(bian)磁場所需要(yao)的電功(gong)(gong)(gong)率(lv)(lv)，這部分(fen)電能(neng)并不做功(gong)(gong)(gong)。

基于(yu)(yu)可(ke)(ke)變性(xing)電(dian)抗(kang)器(qi)(qi)的(de)(de)靜(jing)止型(xing)無功補償器(qi)(qi)拓撲結(jie)構目前基于(yu)(yu)可(ke)(ke)變性(xing)電(dian)抗(kang)器(qi)(qi)的(de)(de)靜(jing)止型(xing)無功補償器(qi)(qi)拓撲結(jie)構主要是(shi)分為兩種：運用(yong)(yong)晶閘管或者是(shi)IGBT的(de)(de)拓撲結(jie)構。倘若電(dian)網系統里的(de)(de)用(yong)(yong)電(dian)負載(zai)是(shi)感性(xing)負載(zai)的(de)(de)話，電(dian)流的(de)(de)速度(du)就會滯(zhi)后于(yu)(yu)電(dian)壓(ya)的(de)(de)速度(du)，我們就要調節晶閘管的(de)(de)觸(chu)發角度(du)，從而使得可(ke)(ke)變性(xing)的(de)(de)電(dian)抗(kang)器(qi)(qi)的(de)(de)電(dian)阻(zu)抵(di)抗(kang)力變小，一直小到期望值。
