摘要
电力线载波通信技术是构建智能电网的重要手段,作为国际公认的技术标准,现有的G3-PLC标准并未规定具体的网络维护方法。该文提出了一种新型Keepalive网络维护机制,该机制同时考虑时效性和可靠性,在保证路由重启后表端能及时入网的基础上,确保了单次未能重入网模块能在较短时间内恢复正常工作状态。该机制在正常工作状态亦可进行网络维护,可协助路由端确认拓扑状态、掌握相位讯息,在链路失效时加速表端确认速度。该机制已通过Vango V63xx+V6000平台确认可行性,对于提高G3-PLC电力线载波通信网络稳定性有一定的实用意义。
PLC communication technology is an important means to build a smart grid.As an internationally recognized technical standard,the G3-PLC standard does not specify network maintenance methods.This paper proposes a novel keepalive network maintenance mechanism.The mechanism considers both timeliness and reliability.On the basis of ensuring that the meter module can access the network in time after the meter module is restarted,it ensures that the module that fails to re-enter the network can return to normal working state in a short period of time.It can also perform network maintenance in normal working state,which can help the router module to confirm the topology status,grasp the phase information,and speed up the confirmation speed of the meter module when the link fails.The feasibility of this mechanism has been confirmed by the Vango V63xx+V6000 platform,and it has certain practical significance for improving the stability of the G3-PLC communication network.
