摘要
介绍了一种基于载波通信的相位识别方法,充分利用了窄带电力载波通信存在的跨相耦合这一特点,仅需在某一已知相位的相线发送含该相位信息的报文即可,接收端通过接收该报文利用时间差和发送端的相位来识别接收相线的相位。该方法便于实现、判决准确,有很好的推广应用价值。
A method to recognizing phase of power based on carrier communication is introduced. It makes full use of the cross coupled characteristic of the narrowband power line carrier communication. The message containing the phase information can be sent at a known phase power line. The receiver can identify the phase by the received message and the time difference. This method is easy to realize and accurate to recognize, and it has significant reference value for the application and popularization.
