摘　　要：根据当前我国低压配电网的通信现状 ,提出了一种采用电力线扩频载波技术的通信网络设计方案 ,并介绍了电力线扩频载波技术以及线性扫频 ( chirp)信号。低压电力线扩频载波通信网支持所有配电自动化功能以及用户服务 ,其设计原则为 :规范通信协议 ;对数据进行封装 ;采用有效的地址分配。同时 ,低压电力线扩频载波通信网还具有抗干扰性强、扩充性好以及与上一级通信网互联容易等特点。Based on the current communication status in low voltage distribution system in China, this paper proposes apower-line spread spectrum carrier communication network (SSCCN) scheme. The proposed SSCCN scheme can support alldistribution automation (DA) functions including customer services because it complies with the standardization of thecommunication protocols. encapsulating transmitted data in standard-format and unique address for one node. Furthermore.the other characteristics of SSCCN are better noise interference,rejection, expandability and easy communication with its highlevel network etc.
