摘要针对传统继电保护动作延时长、整定配合复杂及自适应能力较弱等弊端，引入了利用全站数据信息的站域保护的概念，并分析了站域保护的基本原理和动作功能。从站域保护的通信需求出发，以交换以太网的变电站组网方案为基础，对过程总线通信特性进行评估分析。对过程总线面向间隔以及面向位置的两种组网方案进行了OPNET的仿真和建模，分析了SV报文以及GOOSE报文在过程总线传输过程中的共享特性。验证了当采样率较低时，过程层能够在100Mbit/s网络下实现具有较高实时性的跨间隔数据共享。

Abstract：According to the characteristics of smart substation, the function and principle of substation area protection were discussed. Substation area protection is based on multi-source information, which can overcome the shortcomings of long action delay, complex configuration and coordination, and weak self-adaption in conventional substations. The communication features of process bus are analyzed based on the switched Ethernet substation network scheme. Location network oriented process bus featured with SAV and GOOSE message sharing mechanism is been simulated by using OPNET software. It is verified that data sharing under lower sampling rate and its real-time response ability is basically achieved between the process layer at 100Mbit/s network.
