目前大多数变电站的通信基于IEC 61850标准，但其性能落后于现代通信技术，阻碍了变电站向智能轻量级通信的全面过渡。为此，提出一种通信映射方法，结合简明二进制对象表示（CBOR）格式，将IEC 61850标准映射到受限应用程序协议（CoAP）。首先，给出常用IEC 61850服务的CoAP映射URI和请求方法；其次，对CoAP订阅模式进行扩展，以解决IEC 61850到CoAP映射需求；最后，搭建通信映射模型验证所提出方法的有效性。与现有的WS-SOAP、HTTP映射方案相比，CoAP+CBOR只需要44%、18%的信息大小以及71%、85%的通信时间，可以缓解电网中设备和网络资源受限的问题。
