摘　　要：电力专用无线频率资源较少,制约了电力无线通信技术的发展,挖掘更多可用频谱资源十分必要。受限于现有的频率分配机制,部分已分配并授权的频率资源没有得到充分利用,研究共享利用此类频谱资源具有重要意义。文章对白空间通信技术在智能电网中的应用进行了论述,白空间通信技术可利用授权的空闲频谱资源进行通信,且不对授权频段用户造成干扰,可有效提高频谱利用率,缓解电力无线频率资源不足的问题,促进电力无线通信技术的发展,对智能电网的发展具有一定意义。Limited radio frequency resources for electricity have hampered the development of electric power wireless communication technology, it is necessary to excavate more spectrum resources. Due to the Limitation of the existing frequency allocation mechanism, some allocated licensed spectrum band has not been fully used, it is urgent to develop research on how to use such spectrum resources. The paper discusses the application of the white space communication technology in the smart grid. White space communication technology uses licensed idle spectrum resources to communicate, which will not cause interference to licensed users and improve the spectrum utilization effectively. This technology slows down the shortage of radio frequency resources for electric power system and promotes the development of power wireless communication, which is of signifi cance for the development of smart grid.
