positive-sequence component

基本解释

The positive-sequence fault components based directional relay is a new type of unit for recognizing fault direction.
採用具有選擇性的過電流方曏繼電器，對這種相互分隔直流系統的保護相對就簡單。
A "four var-meter method" for measuring the difference between positive and negative sequence power components is also proposed.
同時還提出了測量正、負序功率分量之差的“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，輸入電流矢量根據輸入電壓正、負序成分進行動態調制。
