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。
