摘要
随着电力行业智能电网的推进和建设,电力4G无线专网作为支撑智能电网的主要手段之一,被提升到了很高的层面。基于电力无线接入控制类业务的高可靠性和低带宽要求,提出了4G无线专网的双层冗余覆盖方案。首先介绍了双层冗余覆盖方案的原理及特点,分析了双层冗余覆盖方案在面覆盖和线覆盖场景中的干扰性能。然后通过仿真验证了双层冗余覆盖方案的应用效果。最后针对双层冗余覆盖方案的不足之处,提出了相应的保障方案和建议。
With the development and construction of smart grid,as one of the main means to support smart grid,power 4G wireless pri- vate network has been promoted to a high level. It proposes a dual redundancy coverage scheme for 4G wireless private net- work based on the features of high reliability and low bandwidth requirements of control service. Firstly,the principle and char- acteristics of the scheme are introduced,and the interference performance is analyzed. Secondly,the application effect of the scheme is verified by simulation. Finally,aiming at the shortcomings of the scheme,the corresponding safeguard plan and suggestions are given.
