節能控制原理

電(dian)(dian)動機屬(shu)感性負載，電(dian)(dian)流滯后(hou)電(dian)(dian)壓，大多數用電(dian)(dian)器都屬(shu)此類。

軟起動(dong)器(qi)節能(neng)控(kong)制(zhi)為(wei)了提(ti)(ti)(ti)高(gao)(gao)功率因數須用(yong)(yong)容(rong)性(xing)負載(zai)來補償，并(bing)電(dian)(dian)(dian)容(rong)或用(yong)(yong)同步電(dian)(dian)(dian)動(dong)機補償。降(jiang)低電(dian)(dian)(dian)動(dong)機的激磁(ci)電(dian)(dian)(dian)流也可(ke)提(ti)(ti)(ti)高(gao)(gao)功率因數（HPS2節能(neng)功能(neng)，在輕(qing)載(zai)時降(jiang)低電(dian)(dian)(dian)壓(ya)，使激磁(ci)電(dian)(dian)(dian)流降(jiang)低，使COS∮提(ti)(ti)(ti)高(gao)(gao)）。節能(neng)控(kong)制(zhi)運行(xing)模(mo)式：輕(qing)載(zai)時降(jiang)低電(dian)(dian)(dian)壓(ya)減(jian)少了激磁(ci)電(dian)(dian)(dian)流，電(dian)(dian)(dian)機電(dian)(dian)(dian)流分為(wei)有功分量(liang)和無功分量(liang)（激磁(ci)分量(liang)）提(ti)(ti)(ti)高(gao)(gao)COS∮。
