摘要
提出了一种在电网电压不平衡且畸变情况下依然适用的补偿电流的准确检测法。该方法能快速检测并计算出电网基波正序电压的相位,从而在三相电压不对称且畸变时仍能准确检测出谐波和无功电流。仿真分析验证了该方法的正确性和可行性。
An accurate method is still suitable for compensation cllrrent when a network voltage is unbalance and distortion.The method can fast detect and work out the phase position of the fundamental harmonic positive sequence voltage of the electric network,so when three phase voltage is unbalance and distortion,the harmonics and reactive current can still be detected.The simulation analysis shows that the method is correct and practicable.
