基于ITER测试平台的无功功率算法研究

国际热核聚变实验堆（ITER）测试平台所带负载为电感很大的超导线圈，当接入电网后会产生大量的无功功率，造成电网电压下降，影响电网质量。为检测ITER测试平台无功补偿及滤波装置对无功功率的补偿效果，通过希尔伯特算法及双谱线插值FFT算法来实现无功功率的计算，并利用数据采集卡及LabVIEW软件来对试验数据进行实时采集、分析和显示。通过和电能质量分析仪的分析结果进行比较，验证了两种算法的正确性。

Research of reactive power algorithm on ITER test platform

The load of ITER test platform is a superconducting coils which has large inductance, when it connected to the grid will produce large amounts of reactive power, resulting in grid voltage drop, affecting power quality. In order to detect the reactive power compensation effect of reactive power compensation and filtering devices, this paper achieves the calculation of reactive power by Hilbert algorithm and interpolation FFT algorithm of double spectral lines, then using data acquisition card and LabVIEW for real time test data gathering, analysis and display. It verifies the validity of the two algorithms by comparing the results of power quality analyzer.
