摘　　要：针对现有的负荷控制终端接入技术施工困难和延时较长的问题,提出了一种基于1.8 GHz TD-LTE无线专网的负荷控制终端接入方法。扩展负荷控制终端和子站通信功能,使其支持UDP协议,把两者接入1.8 GHz TD-LTE无线专网,通过把UDP数据通信转换成1.8 GHz TD-LTE无线通信的方法,实现负荷信息的上送和负荷的控制。经实验验证,新通信方法满足工程要求。新方法具有网络结构简单、组网灵活、施工周期短、成本低、不存在施工许可问题、通信延时低等优点。In response to the difficult construction and long time delay of existing access technology for load control system,a new access technology based on 1.8 GHz TD-LTE wireless private network for the load control terminal is proposed in this paper.The load control terminal and substation communication function are extended to support UDP protocol,and the two are connected to the 1.8 GHz TD-LTE wireless private network.By transforming the UDP data communication to the 1.8 GHz TD-LTE wireless communication,the upload of load information and the control of load are realized.Test results show that the new communication method satisfies the engineering requirements.The new method has the advantages of simple network structure,flexible network,short construction period,low cost,no construction license issue,low communication delay,etc.
