voltage sag detection

基本解釋

The detection and location of the start point and end point of the voltage sag and swell is a key problem for the power quality monitoring.
對(duì)於短時(shí)低電壓擾動(dòng)發(fā)生、恢複時(shí)刻的檢測(cè)與定位則是電能質(zhì)量監(jiān)測(cè)和統(tǒng)計(jì)中獲取相關(guān)指標(biāo)首先要解決的問(wèn)題。

Aiming at the problem of voltage sag with phase jump, considering phase jump based on instantaneous reactive theory minimum energy compensating voltage detection algorithm is proposed.
在此基礎(chǔ)上，針對(duì)伴有相位跳變的電壓跌落問(wèn)題，提出UPQC串聯(lián)側(cè)基於瞬時(shí)無(wú)功功率理論考慮相位跳變的最小能量補(bǔ)償電壓檢測(cè)方法。
At present dynamic voltage restorer(DVR) is an effective device to deal with the voltage sag. Exact detection of voltage sag characteristics is the precondition of DVR's normal working.
動(dòng)態(tài)電壓恢複器（DVR）是目前解決供電電壓凹陷問(wèn)題的有傚裝置，對(duì)電壓凹陷特征量的準(zhǔn)確檢測(cè)是DVR正常運(yùn)行的前提。
