positive-sequence component

基本解釋

The positive-sequence fault components based directional relay is a new type of unit for recognizing fault direction.
采用具有選擇性的過(guò)電流方向繼電器，對(duì)這種相互分隔直流系統(tǒng)的保護(hù)相對(duì)就簡(jiǎn)單。
A "four var-meter method" for measuring the difference between positive and negative sequence power components is also proposed.
同時(shí)還提出了測(cè)量正、負(fù)序功率分量之差的“四乏爾表法”。
In the second one, the input current displacement angle is dynamically modulated as a function of positive-and negative-sequence components of the input voltages.
第二種控制策略中，輸入電流矢量根據(jù)輸入電壓正、負(fù)序成分進(jìn)行動(dòng)態(tài)調(diào)制。
