摘　　要：通过对国内外智能变电站过程层采样值传输组网方式的研究,重点对点对点传输方式和交换机组网传输方式加以分析,总结分析了常见组网方式的特点,并针对其不足,提出了智能变电站分布式同步采样值组网技术方案。与原组网方案相比,新方案的主要长处在于不依赖全局同步系统,从而进一步提高了过程层网络的可靠性。该方案的研究成果已应用于苏州110kV沈巷变电站智能化改造。Based on a thorough study on the networking schemes for sampled values transmission in the process layers in smart substations,the point-to-point scheme and the interchanger networking scheme are analyzed in detail.Then the major characteristics of existing networking schemes are summarized and analyzed.In light of the shortcomings of existing networking schemes,a new networking scheme for sampled values in smart substations based on distributed synchronization is proposed.Compared with conventional networking schemes,the technology proposed does not depend on the global synchronizing system,thus significantly improving the reliability of the process layer networking.This scheme has been successfully applied in the 110kV Shenxiang substation in Suzhou,China.
