| 摘 要： | 基于传统滑模频移法难以兼顾检测速度和对电能质量影响的问题,提出了一种基于根号tan函数的改进滑模频移算法,在有效提高检测速度的同时降低了扰动对电能质量的影响,此外,改进算法的扰动函数具备初始斜率无穷大的特点,可以有效地提高检测可靠性。通过仿真和实验结果验证了算法的准确性和有效性。

| Abstract: | Based on the problem that the traditional slip-mode frequency shift method can not take into account both the detection speed and the impact on power quality,an improved slip-mode frequency shift algorithm was proposed,which could effectively improve the detection speed while reducing the impact of disturbance on power quality.In addition,the disturbance function of the improved algorithm has the characteristics of infinite initial slope,so it could effectively improve the detection reliability.The simulation and experiment results prove the accuracy and validity of the algorithm. |
