voltage sag

基本解釋

Research on a new method of voltage sag measure and voltage compensation strategies .
一種新的電壓凹陷檢測及其補償控制策略研究。
So this paper mostly studies the algorithm of detecting voltage sag, voltage fluctuation and flicker in power quality problems.
因此，本論文確定將電能質量問題中的電壓跌落和電壓波動及閃變現(xiàn)象作為主要研究對象。
Voltage sag , as one of the important aspect of power quality, its research is just underway in our country, which has no criterion related.
而作為電能質量中的一個重要方面――電壓凹陷，在我國的研究則剛剛起步，至今沒有相應的國家標準。

電壓暫降
DVR is the most effective and popular equipment in the voltage sag.
動態(tài)電壓恢復器(DVR)是應用于電壓暫降最有效,也是應用得最多的設備。
電壓凹陷
Dynamic Voltage Restorer (DVR) is considered as the most effective device to compensate the voltage sag.
動態(tài)電壓恢復器(DVR)是目前補償電壓凹陷最為有效的裝置。
電壓跌落
As the installed wind power capacity increased,the grid code have required the wind turbines must have low voltage ride-through(LVRT) capability,a voltage sag generator(VSG) is the important equipment for wind tu-bines to evaluate the operation capacity of LVRT.
隨著新能源中風力發(fā)電容量占電網比重的不斷增加,新的電網運行準則要求風電機組具有一定的低電壓穿越運行能力,電壓跌落發(fā)生器是測試風電機組低壓穿越性能的重要裝置。
電壓驟降
However, it has weakness in dealing with grid fault yet. The voltage sag is the most important one which caused by short circuit or open circuit.
電壓驟降是電網故障常見的表現(xiàn)之一,主要由輸電線路短路或斷路引起,當電網故障造成電壓驟降時,對風電機組的安全持續(xù)運行和維持電網的穩(wěn)定形成了極大的挑戰(zhàn),所以提高雙饋式風電機組低電壓穿越的能力成為研究熱點之一。
