电力无线专网干扰源跟踪定位方法
|
摘要
针对电力无线专网在建设中存在的干扰源无法确定位置的问题,为更好地服务智能电网和开展TD-LTE技术在电力通信等领域的应用研究,提出一种LTE电力无线专网网外干扰源故障跟踪定位的方法。该方法首先确定被干扰基站的范围,再确定干扰源搜索范围;针对搜索范围,进行三维场景建模,然后规划路测路径进行路测,提取路测的数据特征,分析逼近干扰区域;最后通过正向射线跟踪,评估筛选出实际的干扰源位置。该方法为电力无线专网网外干扰分析定位排查提供技术支持和方法论指导,有利于解决电力无线专网建设中的干扰问题。
To solve the problem of failure in determining interference sources in construction of power wireless private networks, and better serve smart grids and develop application research of time division long term evolution(TD-LTE) technology in electric power communication, this paper presents a kind of fault tracking and location method for external interference source of long term evolution(LTE) power wireless private network. This method firstly determines range of the interfered base station and then searching range of interference sources. According to search range, 3 D scene modeling is carried out by using this method and the drive test path is planning for drive test. Data characteristic of drive test is extracted for analyzing and approximating the interfered regions. Finally by means of positive ray tracking, actual interference source locations are evaluated and selected. This method can provide technical support and methodology guidance for external interference analysis and location investigation and is beneficial to solve the problem of interference in construction of the power wireless private network.
