摘要
对美国宇航局（ＮＡＳＡ）诺拉发明的感应式电动机功率因数控制器的节能效果进行了试验研究。发现以额定功率因数为给定值的功率因数控制器，其节能效果并非最佳，进而提出根据不同负载确定不同功率因数给定值的随动功率因数控制方式。试验证明：随动功率因数控制方式的节能效果优于恒功率因数控制方式的节能效果。
The power economy effects are studied for a power fact controller, which are invented by Nola. In the test of the power factor controller, the author discovered that the power economy effects of the power fact controller are not best. Through tests and researches, authors present a controller with variable setting power factor. The best economy effects of the proposed controller are demonstrated by tests.
