In order to change the traditional measurement of reactance value of reactor,this paper presents a method based on the PWM control which can be carried out impedance measurement under the rated current,and the power is the three-phase symmetrical current source.
传统电抗器电抗值的测量方法为外加三相对称电压源的方法,而电抗器的设计是按三相对称电流源设计的,在实际运行中电抗器两端相当于外接一个对称三相电流源,因此,用传统的测量方法必定引起测量误差。

提出建立一个发生对称三相电压的动画模型,对其进行规划设计,并在微型计算机上开发实施。
补充资料:三相
【三相】
(名数)一、解脱相,言无生死之相也。二、离相,言无涅槃之相也。三、灭相,言生死涅槃之无相,其无相亦无。即非有非无之中道也。法华经药草喻品曰:“如来说法,一相一味,所谓解脱相离相灭相。”文句七上曰:“解脱相者,无生死相,离相者,无涅槃相,灭相者无相,亦无相。”又曰:三有为相。(参见:有)
