摘要
以PMU为基本单元构成的广域电网相量同步测量是现代电力系统运行状况实时动态监测、分析和控制的基础。已研制的嵌入式PMU由测量DSP和人机交互(MMI)两部分构成。鉴于测量的高实时性和高可靠性,两者之间的数据传输有着较高的要求。利用TMS320C6000系列DSP中的16位HPI接口、PC104总线及CPLD芯片EPM7128S设计了一个嵌入式PMU内部数据传输的高速通信通道,并在QNX平台下开发了接口的相关软件。所设计的接口在开发的样机中得到应用,提高了PMU内部数据传输速度,提高了PMU的整体性能。
Wide Area Measurement System(WAMS)which uses PMU as basic unit is a fundamental system of modern power system for real-time dynamic supervision,analysis and control.The developed embedded PMU consists of two parts: DSP and MMI,which need high speed data transmission between them to satisfy the high speed and reliability requirements of measurement.An embedded high-speed channel for internal data transmission of PMU is designed based on 16-bit HPI interface of TMS320C6000 series DSP,PC104 bus and EPM7128S of CPLD chip,and the corresponding software is developed on QNX platform.The interface designed has been applied in sample machine which improve the internal data transmission speed and the whole performance of PMU.
