随着智能电网近年来的快速发展,我国迫切的需要建设经济费用合理且技术先进的电力通信网。近年来,发展日渐成熟的无线网络通信技术具有非视距、传输能力强、抵抗自然灾害能力强、传输距离远、带宽大、不受限于地面线路结构等一系列的优点,及其适合应用于建设电力无限专网。就目前而言,配电网通信的发展方向就是将无线宽带技术中的TD-LTE技术应用于电力无线宽带专网的建设中。与其他的移动通信网络一样,TD-LTE网络在应用时也需要对其进行相关的网络规划,其中TD-LTE无线传播模型参数校正工作是其规划的最基础工作。
With the rapid development of smart grid in recent years, China urgently needs to build a power communication network with reasonable cost and advanced technology. In recent years, the development of increasingly mature wireless network communication technology has a series of advantages of non-line-of-sight, strong transmission capability, strong resistance to natural disasters, long distance transmission, large bandwidth, not limited to the ground line structure and its suitability for application In the construction of electricity unlimited network. For now, the development direction of distribution network communication is to apply TD-LTE technology in wireless broadband technology to the construction of power wireless broadband private network. As with other mobile communication networks, TD-LTE networks also need to be network-related in their application. Among them, the calibration of TD-LTE radio propagation model parameters is the most basic work of its planning.
