摘要
双向工频通信技术(TWACS)是一种基于电力配电网的新型数字通信技术。该文介绍了双向工频通信的基本原理,建立了工频通信的仿真模型,说明了调制信号产生的机理、推导了信号在线路中传播以及通过变压器时的传输特性,并应用小波变换对通信信号进行时频分析以服务于信号提取。
TWACS is a new communication technology for distribution networks. This paper introduces the basic principle of TWACS and creates a simple simulation model. The generation of signal and the transmission characteristics when propagate in line and through transformers are presented. Time-scale analysis is performed by wavelet transform, and the results are helpful in signal extraction.
