发变组保护装置界面&通信管理单元的设计与实现

Design and implementation of generator/transformer protection device MMI and communication management unit

随着数字化电厂的发展,电力系统对继电保护装置界面及通信的功能、性能提出了更高的要求。在对发电机变压器组保护装置的界面及通信功能相关需求进行全面分析的基础上,提出了一种基于AM3352芯片及QNX嵌入式实时操作系统的界面&通信管理单元设计方案,并从软硬件平台选择、软件架构设计、软件流程设计等方面对设计方案的实现进行了阐述。

With the development of digital power plant,it brings higher requirements for the MMI,communication function and performance of relay protection devices.Based on the comprehensive analysis of the generator/transformer protection device MMI and communication management unit,a design scheme that includes chip AM3352 and embedded real-time operating system QNX is proposed.The design scheme is expounded from software/hardware platform selection,software architecture,software process design,etc.
