摘要/Abstract

摘要： 为降低合并单元设备成本、增强其智能化和通用化特性，利用多ARM（高级精简指令集处理器）并行处理的优势来构建智能合并单元。采用灵活的模块化方式来进行总体架构的设计，通过光纤接口方式与其他智能电子设备建立基于快速以太网的双向通信，遵循IEC 61850通信标准进行采样值报文和GOOSE报文的高速网络化传输。结合数据处理和报文传输的要求，详细阐述了采样控制和开入开出控制等核心部分的软件处理流程。采样值及GOOSE传输等相关测试结果表明，该智能合并单元工作可靠而稳定，可满足智能变电站中合并单元在实时性强、可靠性高、通信流量大等方面的要求。

Abstract: In order to reduce the facility cost of merging units and enhance their intelligence and versatility, an improved intelligent merging unit using multi-ARM for smart substations is proposed. The design procedure of its hardware and software is presented in detail. Flexible modular patterns are utilized for the whole framework design, and fiber interfaces are used to establish the bi-directional fast Ethernet communications between the system and other intelligent electronic devices. With the help of high-speed network communication, standard sampled values and GOOSE messages can be sent and received reliably based on IEC 61850. In addition, the software flows of critical modules such as sampling and switch-in/switch-out control modules are illustrated. The test results on the transmission of sampled values and GOOSE messages demonstrate that the equipment works reliably and steadily, and it shows high performances of real-time, dependability and communication speed, which greatly satisfies the needs of smart substations.
