摘　　要：本文通过使用广义二阶积分器锁相环替代传统的过零比较锁相提取电流、电压中的相位,并通过特定的运算求出补偿量,该算法可以在谐波含量大和有突变得情况下,快速准确的检测到电流、电压的相位。此外,使用无功功率和功率因数复合的控制方式,改进传统功率因数控制带来的临界震荡的现象。In this paper ,Using SOGI phase lock technology instead of the traditional zero hold compare Technology to extract the phase current and voltage, the compensation amount was given that the specific operation. The algorithm can fast detection to the phase current and voltage under the condition of the harmonic content and frequency of mutations. Moreover, the critical shock Phenomenon was eliminated compound of reactive power and power factor control mode compare traditional power factor control.
