瞬态恢复电压波形参数提取算法的研究

Study on Algorithms for Waveform Parameters of Transient Recovery Voltage

采用一种基于最小二乘原理和牛顿迭代原理的方法计算了一种瞬态恢复电压波形参数,对于电压波形中不同的参数采用不同的多项式进行了局部拟合计算。结果表明,此方法具有较好的精确度。

This paper presented a method based on the least squares theory and Newton iteration method to calculate the parameters of transient recovery voltage waveforms. Different polynomial expression had been used for partly fitting according to different parameters. The calculating results show that it has relatively high precision.
