基于DSP的高压节点在线测试系统设计

摘要

With the high voltage electrical equipment increasing in oil petrochemical indus-try, in order to test the operation energy consumption and performance under different con-ditions. In view of lacking portable high voltage electric parameter online test equipment, designed the electrical parameters acquisition and processing circuit with DSP as the core, which realizes high speed data transmission between the host computer by the network com-munication interface based on TCP/IP protocol, and makes the high voltage electrical nodes electrical parameters display more intuitive, more specific and more vivid. The field experi-ments show that the system can collect data in real time based on DSP high voltage electric node online testing system, which has high accuracy in measuring parameters, and play an important role in safety production and energy saving for oil enterprises from now on.%随着石油、石化行业中高压用电设备的不断增加，需要对设备运行能耗以及不同工况下的性能进行测试，但目前油田缺乏高压节点电参数测试设备。基于DSP为核心的电参数采集处理电路，采用TCP/IP协议的网络通信接口实现与上位机之间的高速数据传输，实现了高压节点电参数直观、具体、形象的显示。现场实验表明，采用DSP高压节点在线测试系统可以实时采集数据，且具备较高的计量精度，相对误差维持在3%以内，能够达到测试要求。
