摘　　要：在电力有源滤波器设计中,谐波电流的实时检测是控制与补偿的关键技术环节。基于坐标变换和瞬时无功理论,得到谐波电流值。为了验证理论分析,进行不控整流桥带容性负载的非线性负载仿真。基于Matlab/Simulink的仿真结果表明可以有效地得到电流中的基波和谐波成分。Abstract： In the design of active power filter, the real-time detection of harmonic current is the key technique of control and compensation. The value of harmonic current is got on the basis of the theory of coordinate transformation and instantaneous reactive power. Meanwhile, to verify the theory＇s analysis, the nonlinear load which is the uncontrolled bridge rectifier with capacitive load is simulated by Matlab/Simulink. The simulation results show the fundamental and harmonic components of the current can be obtained effectively.
