摘　　要：为了掌握学生公寓用电负荷的使用情况,从而更好的限制违章电器的使用,保证用电安全,运用傅立叶变换对学生公寓用电负载的波形进行分析与讨论,利用电压和电流的各频率分量的幅值和相位的对应关系,对学生公寓典型的负荷特性进行研究。该方法能够识别出学生公寓的典型负荷,在实际应用中具有可靠性和实用性。In order to know the status of electrical appliances being used in the student apartment, so as to prohibit the use of disallowed electrical appliances and ensure the students＇ safety. The wave of electrical appliances being used in the student apartment is analyzed and discussed with fast Fourier Transform, so that we can obtain the components of the signals of different frequencies and make use of the relative relationship of their range and phase to research the typical electrical load property. The results show that the method can recognize the typical load effectively and reliably.
