摘要： 摘要：为了满足智能电网对于信息传输的要求，尽可能保证电力系统主子站间信息传输的“不漏不多”，分析了智能网关机双主运行的缺点，提出子站双智能网关机“对下独立，对上主备”的逻辑通道冗余方案，简要分析了实现机制，规范化主子站间的主备机制，提高了电力信息传输的可靠性、准确性。

Abstract: Abstract:In order to meet the information transmission demand of smart grid and to ensure the massage transmission between the master station and substations of power grid to be “no omissions and no additional” as far as possible, the defects of the intelligent gateway in double main gateways operation mode were analyzed, and a logical channel redundant scheme, in which the two intelligent gateways in the substation operate in “standalone mode for lower layer and mainstandby mode for upper layer”, was proposed. The implementation mechanism of the scheme was analyzed briefly. The mainstandby mechanism between main station and substations was normalized. The reliability and the veracity of the electric power information transmission were improved.
