同步发电机参数测量中数据处理的研究

Data Treatment in Synchronous Alternator Parameter Measurement

在用紫外线示波器记录同步发电机短路电流波形求取发电机暂态参数时，很难准确描出０″时电流波形的包络形，使得描出的包络线计算的暂态参数误差很大。

In case of experimental study of synchronous laternator short circuitcurrent wave form detection by means of an ultra-violetray oscillograph, it often happened that it is hard to take accurately the envelope ofthe wave form at O″ instant, so that rather great error is introduced.This article presents a comparatively good method to solve the problem.
