| 摘 要： | 电力故障波形重现装置可以将各发电厂、变电站的录波器所记录的标准COMTRADE格式故障数据真实还原成实际电压电流波形,进行故障分析、研究继电保护装置动作行为以及测试电力二次设备等。装置采用嵌入式PC与DSP的双CPU控制结构,为保证输出波形失真小,需要传输大量数据,因而嵌入式PC与DSP之间准确、快速的通信成为提高装置性能的一个重要问题。概括介绍了故障波形重现装置的原理、结构等,并重点对上、下位机间的串行通信做了一个详尽的描述。该装置已通过试验验证,具有很强的实际价值。

| Abstract: | The obstacle recurrence device of power system could recur the fault recording data based on standard COMTRADE into real voltage or current wave, which can use in fault analysis, studying motion of relay test system and testing secondary equipment of power system. The device, which adopts double-CPU design of embedded PC and DSP, needs communicating massive data, for reasons of less nonlinear distortion. So an exact and fast communication between PC and DSP becomes an important problem for advancing capability of the device. This paper details the elements and structure of the device, and describes the serial communication at large. The device shows its powerful practical value after test. |
