摘　　要：随着能源互联网的发展,智能电网中智能变电站得到了快速发展,继电保护装置的分布式布置已成为必然趋势。为应对智能变电站继电保护分散化布置、信息远程控制等问题,提出了基于工业无线通信技术的变电站就地化保护方案。依据变电站特点,将工业无线通信系统应用于变电站就地化保护站控层,实现对变电站现场设备监测,开发适用于变电站环境的无线通信模块,进行实验室及现场测试,试验证明该方案可实现变电站复杂环境下高可靠、实时的数据传输,为后续智能变电站就地化保护研究提供参考。With the development of energy Internet,intelligent substation in smart grid has been developed rapidly,and the distribution layout of relay protection device has become an inevitable trend. In order to dealwith the intelligent substation relay protection decentralized arrangement,information remote control and other issues,this paper puts forw ard local relay protection scheme for substation based onwireless networks for industrial automation（ WIA）. According to the characteristics of the substation,the industrialwireless communication system is applied to the local relay protection control station of substation,which can monitor the substation locally installed device. We develop thewireless communication module for substation,and carry out the laboratory test and field test,while,the experimental results show that the proposed scheme can achieve high reliable and real-time transmission in complex environment,which has a certain reference value for the follow-up study of local relay protection in intelligent substation.
