摘要
跨台区电力通信是一种新型的基于配电网络的通信技术 ,其调制信号的波形是确定的 ,将该波形与接收信号波形作互相关运算 ,提高了系统信号噪声比 ,这种信号检测方法可靠性大大优于先前采用的基于时间测量的信号检测方法 ,现场应用效果良好。文中分别介绍了跨台区电力通信基本原理、互相关信号检测原理及其在跨台区通信中的应用。
The power line communication that can exchange data between two voltagestages is a new method for data transmission over distribution power net.For the modulated wave is definite,the SNR can be enhanced when we calculate the cross-correlation functions between the received signals with the modulated signals.In field trial,it gets an advantage over the way of the measurement based on time variety.In this paper,the basic theory of power frequency communication,the detection method for correlation function and its application in power communication will be introduced.
