摘要
分析了已有的电抗测量技术存在的不足,提出了一种利用电抗-相位转换、通过测量相位差来获取高频工作条件下的电抗值的方法。该方法采用多周错位采样法实现对高频信号的低速采样,并通过相关运算计算相位差进而求解电抗值。仿真实验验证了方法的可行性,同时分析了各种实验参数对测量误差的影响。
After analyzing the deficiencies of existing measurement techniques for reactance, a meth- od, which using reactance-phase transform and phase difference detection, is proposed and can be used in high frequency working condition. This method applies multiple cycle dislocation sampling （MCDS） to achieve low speed sampling for high frequency signal, and solves reactance value by phase difference calculation with correlation operations. Simulations verify the feasibility of this method. Some experiments also are carried out to test how much the experimental parameters have impact on measurement error.
