voltage sampling meaning in Chinese

电压抽样

Firstly , the voltage sample signals from ac exciter stator coil were de - noised and filtered by means of decomposition of the wavelet function . secondly , the character frequency region of the rotating rectifier fault was selected clearly with wavelet package decomposition and reconstruction
先对交流励磁机定子磁极线圈电压采样信号进行消噪滤波，再通过小波包分解和重构进行特征频率提取，建立了表征旋转整流器故障的特征向量。
So it is very important to investigate the inverse time characteristic of microprocessor distance protection . this paper emulates all kinds of faults of transmission lines by using emtp , and gets relative current and voltage sample values . then many distance protection thoughts and algorithms are adopted to compare each inverse time characteristic , better arithmetic and set thoughts are got
本论文应用emtp进行输电线路各种故障情况的仿真，采样取得保护相关的电压、电流数据；采用各种距离保护思想、算法，采用c语言进行计算，比较各自的时限特性，得出反时限特性比较好的算法及其整定思路；对于各种故障情况，应用相关整定思路进行离线计算，得出各种原理的时间距离特性。
