line-voltage variation

基本解释

Orthogonal Multi-Carrier Modulation(OMCM) is adopted to overcome the frequency selectivity and time variation of low-voltage power line channel.
为克服低压电力线信道的频率选择性和时变性，系统采用正交多载波方式传输信息。
In the voltage correction the voltage variation of tie-line nodes is considered and is added into the traditional secondary voltage control as the feedback.
在电压校正中，考虑了区域联络线节点的电压变化，并以此作为反馈添加到传统的二级电压控制中。
The experimental results show that this system can complete monitoring temperature variation of high voltage devices real time on-line, it also proves that the proposed project is practicable.
实验表明，该测温方法完全可以实现对高压电器内部温度的实时在线监测，该测温方案是切实可行的。
