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。
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.
