一种基于故障录波数据的电气量计算方法
摘要：
本发明涉及一种基于故障录波数据的电气量计算方法，包括以下步骤：S1.对故障录波文件进行解析；S2.对解析后的故障录波文件通道i的采样值进行读取，为通道i建立一个对象，然后采用零交越法对各个通道的采样频率j进行预估；S3.采用DFT方法对故障录波文件通道i一个采样周期内的采样频率k进行计算，并利用采样频率k对采样频率j进行矫正；S4.基于采样值、采样频率计算电气量有效值和相角，然后将有效值和相角存入通道i相对应的对象中。
摘要（英）：

The invention relates to an electrical quantity calculating method based on fault recording data; the method comprises the following steps: 1, parsing a fault recording file; 2, reading a sampling value of a parsed fault recording file channel i, building an object for the channel i, and using a zero-crossing mode to pre-estimate a sampling frequency j of each channel; 3, using a DFT method to calculate a sampling frequency k in one sampling period of the fault recording file channel i, and using the sampling frequency k to rectify the sampling frequency j; 4, calculating an electrical quantity effective value and phase angle according to the sampling value and sampling frequency, and storing the effective value and phase angle into the object corresponding to the channel i.
