为了提高船舶电力系统的安全性和可靠性，本文通过对船舶电力系统的特点和需求进行分析，设计了一种电力系统智能继电保护整体方案，分别从方案开发的软件层面和硬件层面进行详细介绍。硬件层面采用了模块化设计的方法，根据继电器保护的原理搭建了模块的功能和接口，基于TMS320F2808搭建了高性能的信号处理上位机；软件层面基于Microsoft Visual Studio 2008设计了相应的软件架构，包括数据采集模块、数据处理模块和控制模块等。最后，基于虚拟仪器技术进行了电力系统智能继电保护方案的仿真测试。
In order to improve the safety and reliability of the ship power system, this paper designs an overall scheme of intelligent relay protection for the power system by analyzing the characteristics and requirements of the ship power system. The software and hardware aspects of the scheme development are introduced in detail, and the modular design method is adopted in the hardware aspect. The function and interface of the module are set up according to the principle of relay protection, and the high performance signal processing host computer is set up based on TMS320F2808. At the software level, the corresponding software architecture is designed based on Microsoft Visual Studio 2008, including data acquisition module, data processing module and control module, etc. Finally, the simulation test of intelligent relay protection scheme of power system is carried out based on virtual instrument technology.
