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.
采用具有选择性的过电流方向继电器，对这种相互分隔直流系统的保护相对就简单。
A "four var-meter method" for measuring the difference between positive and negative sequence power components is also proposed.
同时还提出了测量正、负序功率分量之差的“四乏尔表法”。
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.
第二种控制策略中，输入电流矢量根据输入电压正、负序成分进行动态调制。
