signal injection meaning in Chinese
信号注入
Examples
- How to improve the accuracy of flux observer is very important in high - performance motor system , especially at low - speed or zero - speed situation . high - frequency signal injection is believed the efficient method to solve these difficuilties
高频信号注入来实现极低速甚至零速情况下磁链位置的观测是目前该领域的热点研究内容，本文采用的是d - q轴阻抗差异法。 - The principle of the fault distance measurement for small current grounding system by injecting dual frequency signal are discussed from many aspects such as the method and the characteristic of the signal , the test of the signal , the method of the line select , the algorithm of the fault distance measurement , and the method of the fault location , etc . the task adopts this kind of principle , in which the signal injection is completed by the coupling between the power source and the pt
在详细地说明以上三种测距算法的基本原理后，分析各种算法的优缺点，从注入信号的方法、特征，注入信号的检测，接地选线的方法，故障测距的算法，及故障定位的方法等多个方面，论述了本课题采用的应用于小电流接地系统的双频信号注入式测距原理。其中，信号的注入由功率源通过电压互感器( pt )耦合来完成。
