| 摘要: |
| 电力参数测量是获取电能质量信息的关键技术。不仅需要大量的数据，而且在精度、速度上要求也很高。以高速数据采集卡PCI2003为核心，结合功能强大、界面良好的编程语言VB6.0设计了一套电力参数测量软件。为了提高测量精度，采用AD202，MAX275和运算放大器组成信号调理电路．它具有隔离、放大、滤波的作用。详细介绍了信号调理和基于PCI2003的电力参数测量方法并给出了VB的设计程序。 |

| Abstract: |
| Power parameters measuring is the key in power quality information acquisition.Not only large amount but also higher precision and speed are required.Based on high-speed data acquiring card PCI2003,a new power parameters measuring software is developed using Visual Basic6.0.The signal processing circuit applies AD202,MAX275and operation amplifier to improve the measuring accuracy,which has the functions of separation,amplification and filter.The signal pro-cessing and parameters measuring method are given with the VB programs. |
