摘要
研究了促成相量法提出的三篇文献,分别探讨了它们的主要内容、成文背景和历史地位。结果表明:1886年7月,亥维赛在分析外加振荡电动势的效应及其在长途电话和电报信号传输中的应用时,首次提出"阻抗"术语,并将它定义为传输线上外加电动势振幅和电流振幅之比;1893年4月,肯涅利将亥维赛定义的传输线的阻抗推广到一般交流电路和设备的阻抗,并使用复数表示阻抗;1893年8月,施泰因梅茨为了分析通用电气公司为尼亚加拉瀑布水电站设计的三相系统中相间的不平衡现象,在肯涅利使用复数表示阻抗的基础上,用复数表示正弦电压和正弦电流,提出了相量法。
The three classical papers giving birth to the phasor method were studied,and their main content,written background and historical status were discussed respectively.The results are as follows.When analyzing the effect of oscillatory impressed force and its application to the signal transmission of long-distance telephony and telegraphy in July 1886,O.Heaviside coined the terminology 'impedance' and gave its definition.The impedance was defined as the ratio of the amplitude of the impressed force to that of the current on transmission line.In April 1893 A.E.Kennelly extended the impedance of transmission line defined by Heaviside to that of the general alternating-current circuit and apparatus,and represented the impedance by complex number.Based on Kennelly’s work,C.P.Steinmetz expressed the sinusoidal voltage and the sinusoidal current by complex number and proposed phasor method in August 1893 in order to analyze the unbalanced phenomenon between the three phases of the three-phase system designed for Niagara Falls hydropower station by General Electric.
