摘要:: 为了解决现有光电互感器校验系统在精度和稳定性上的不足，该文设计了一种基于LabVIEW平台的光电互感器校验仪。系统由前端信号处理模块、采集卡和LabVIEW平台上位机软件组成，采用IEC61850协议实现数据通信，通过直接比较被测试互感器信号和标准互感器信号，实现被测互感器比差和角差的测量。实验结果表明系统测量精度高于0.5‰，能够完成对0.02级光电互感器的校验，在甘肃某330kV数字化变电站进行了现场测试，系统稳定性满足要求。

Abstract:: In order to solve the deficiencies in existing photoelectric current transformer calibration system on the accuracy and stability, a kind of photoelectric transformer verification based on LabVIEW platform is proposed in this dissertation . The system is composed of signal-processing module, acquisition card and the LabVIEW upper-computer software, adopts IEC61850 communication protocol. By direct comparison between tested transformer signals and the standard transformer signals, the system can measure transformer ratio and phase error. The experiment results show that the system have an accuracy higher than 0.5‰, completing the checking for 0.02 class digital optical multiplex transformer. In Gansu Province, a 330kV-digital substation was do the site testing using this program and stability of the system meet the requirements.
