摘　　要：传统的保护方法采用时帧分布调节方法实现智能电网网络信道交叉映射,实现过载保护和网络节点管理,容易导致智能电网计算机网络节点信道偏移,数据丢包率较高,安全性差。提出基于端到端数据融合滤波的具有容错性的计算机网络下智能电网安全保护机制。构建计算机网络下的电网节点优化分布模型,采用网格形式部署,对过载节点进行数据融合与滤波处理,提高电网节点的容错性能;采用预加重方法补偿智能电网计算机网络节点之间的系统功率衰减,实现安全保护优化。仿真结果表明,采用该算法能准确实现对智能电网中的网过载的失调节点定位,电网进行能量传输稳定性较高,抗干扰性能较好,有效实现了电网的安全保护。The Traditional protection method adopts the frame distribution adjustment to realize the smart grid network channel cross mapping and achieve the overload protection and network node management. This method may easily cause the smart grid channel offset and lead to bigger loss rate of com- puter network node data packet, therefore its safety perfor- mance is poor. This paper puts forward a smart grid security protection mechanism under the computer network based on end-to-end data fusion filtering and with tolerance for faults. A grid node optimization distribution model is built in the computer network while the overload nodes undergo data fusion and filtering using the grid form deployment to enhance the fault tolerance performance. The pre-emphasis method is used to compensate the system power attenuation between the computer network nodes of the smart grid to realize the safety protection optimization. The simulation results show that the algorithm can accurately realize localization of the overload disorder nodes in the smart grid and improve the grid energy transmission stability and anti-interference performance, thus effective protection of the grid is realized.
