| 摘 要： | 讨论了四象限变频器的缺相故障快速检测及相序自适应的方法。通过基于双广义二阶积分的软件锁相环,分别对三相电压正序和负序进行锁相,获得三相电压在两种相序下的幅值。对三相电压各种情况所对应的正序、负序分量进行分析,结合锁相环计算出的正序或负序分量的幅值,分辨出三相电压是否过低或缺相及相序情况。经过MATLAB/Simulink仿真验证,15 ms内即可对缺相故障及相序做出准确分辨,证明所述方法切实可行。

| Abstract: | The method to detect phaseloss and phasesequence of quadrant frequency converter was focused on. Lock the phase and obtain the amplitudes of positive and negative phasesequence separately using dual second order generalized integrator PLL (DSOGIPLL). Analyze all possible threephase voltage of grid and compute the corresponding positive and negative amplitudes, combined with calculation of DSOGIPLL in real system, predict the phasesequence and faults happened to power supply. Simulation based on MATLAB/Simulink and experiment in real system showed that the method could make accurate judgment to faults and sequence of grid within 15 ms. |
