摘　　要：电力系统通信网络是电网安全稳定运行的重要基础。针对电力系统通信传输网,分析了SDH和PTN网络的技术实现原理和时间同步技术。根据电网对传输网络承载E1业务和以太网业务的性能要求,在实验室环境下搭建了网络测试平台,测试了传输网在承载不同业务时的网络性能。实验测试结果表明,SDH和PTN网络对E1业务和以太网业务具有较好的承载能力,可满足传输网的性能要求。最后,对进一步提高SDH和PTN传输网的可靠性提出了几点建议。The communication network of power system plays a foundational role on the security and stability of power grid. In view of the communication transmission network of power system,the technical realization principle and time synchronization technology of SDH and PTN networks were analyzed. According to the performance requirements of the power grid for the transmission network carrying E1 and Ethernet services,a network test platform was built under the laboratory environment,and the performances of the transmission network under different services were tested. The experimental results show that SDH and PTN networks have favorable capacity for carrying E1 and Ethernet services,which can satisfy the performance requirements of the transmission network. Finally,some suggestions are presented to further improve the reliability of SDH and PTN transmission networks.
