摘要
通过分析港口电网谐波问题,建立三相四线制非线性负载谐波补偿系统的数学模型,提出基于参考电流控制的有源滤波控制策略,并构建了仿真系统,最后通过仿真和实验验证了该控制策略能够有效滤除电网中的谐波电流,使港口电网质量得到补偿和改善。
By analyzing the harmonic problem of port power grid,the mathematical model of nonlinear load harmonic compensation system of three-phase four-wire is established.An active power filter control strategy is proposed based on the control of reference current,and the simulation system is set up.Finally,simulation and experiment results illustrate that this control strategy can effectively filter out harmonic current in grid,the port power quality can be compensated and improved.
