摘要
数字化变电站中电子式互感器与二次设备的数字接口是变电站自动化技术的一个关键点,该文分析了电子式互感器标准和IEC61850标准中对数字量输出的要求,并给出数字接口数字量通信帧的实现方案。在此基础上,提出了一种基于现场可编程门阵列(FPGA)和数字信号处理(DSP)技术的接口设计方案,详细介绍了硬件和软件设计方法。试验结果表明,该方案可以很好地实现数字接口。
In the digital substation and secondary equipment electronic transformer of substation automation technology digital interface is a key point,this paper analyzes the electronic transformer standards and IEC61850 standard of digital output requirements,and give digital interface the digital quantity communication frame scheme.On this basis,this paper puts forward a based on field programmable gates array(FPGA) and digital signal processing(DSP) technology interface design,detailed introduces the hardware and software design method.Experimental results show that the scheme can be well applied to the realization of digital interface.
