摘要
设计一套应用于EAST无功补偿及滤波系统的数据采集系统,该系统由传感器单元、采集卡单元、运算单元等几部分组成。实现了对10kV母线电压、10kV母线电流及极向场负载电流等数据的实时采集,并通过Hilbert变换和相关无功功率理论,借助LabVIEW编写算法,将所采集电压电流信号演算成极向场电源运行时产生无功功率。此系统已经用于EAST实验中,实验证明该系统具有良好的实时性和稳定性,满足EAST实验需求。
A set of data acquisition system has been applied for EAST reactive power compensation and harmonic filter system,which consists of sensor unit,DAQ card unit,operating unit,etc.It has accomplished to acquire the experimental data such as 10kV bus voltage,10kV bus current and loading current of poloidal filed power supply in real time.The reactive power which has been made by the poloidal filed power could be calculated by using Hilbert transform and corresponding reactive power theory.The LabVIEW has been chosen to be the software platform.This system has been used in the EAST experiment,and the result proves that it gets wonderful real-time work and stability.It satisfies the requirement of the EAST experiment.
