| 摘要: |
| 为解决智能变电站新建及改造过程中二次设备配置繁琐和文件生成复杂的问题，提出了智能变电站二次设备即插即用理论模型。为实现即插即用的功能，首先设计了二次设备即插即用框架，针对设计的框架，从硬件层面和软件层面实现需求功能。硬件方面采用双核异构处理器外加FPGA构成的三核硬件平台，软件方面实现分层化设计，由支持层、功能层、应用层系统组成，实现了层与层的解耦，便于后期维护和软件组件的重用。在二次设备模型基础上，增加即插即用特有的数据及功能描述，从设备、数据和功能三方面进行了说明。为测试功能应用，进行保护和测控两方面验证仿真。同时设计了二次设备顺序控制、防误闭锁、五防闭锁和虚端子校验等方面控制校核逻辑。最后，通过功能测试证明了所设计模型可正确自动进行设备配置的读取、下装和相关参数配置修改。 |

| Abstract: |
| In order to solve the problem of cumbersome secondary equipment configuration and complex file generation in the process of new construction and transformation of smart substations, this paper proposes a plug-and-play theoretical model of secondary equipment. In order to realize the plug-and-play function, a framework for secondary devices is first designed, and for the designed framework, the required functions are realized at the hardware and software levels. In terms of hardware, a triple-core hardware platform composed of dual-core heterogeneous processors and FPGA is adopted. In terms of software, a hierarchical design is realized. It is composed of a support layer, a functional layer, and an application layer system. These accomplish the decoupling of layers and facilitate subsequent maintenance and reuse of software components. For the secondary equipment model, it adds plug-and-play unique data and a function description, and elucidates the three aspects of equipment, data and function. To test the application of functions, simulation of protection and measurement and control is carried out. Also the control and verification logic of secondary equipment sequence control, anti-error locking, five-proof locking and virtual terminal verification are designed. Finally, the functional test proves that the design model can correctly and automatically read the equipment configuration, and download and modify the configuration of related parameters.
