摘要
为了解决微电网中的谐波问题,使微电网公共耦合点的电能质量得到改善,该文采用分层控制策略,通过一次控制和二次控制分别对微电网中的谐波进行治理。其中一次控制进行基本的控制,二次控制通过公共耦合点补偿控制计算模块和APF补偿控制计算模块共同对微电网的电能质量进行治理。各个模块及各个控制层之间互相配合,最后通过MATLAB仿真模型的验证,证明该文所提的控制策略能很好地解决谐波问题。
In order to solve the problem of harmonic in the microgrid,the power quality of the common coupling point of the microgrid is improved. In this paper,the hierarchical control strategy is adopted to control the harmonics in the microgrid by one control and two control. One control is the basic control,the two control is the power quality control of the microgrid through the PCC compensation control calculation module and the APF compensation control calculation module. Each module and each control layer cooperate with each other. Finally,the MATLAB simulation model is verified,which proves that the control strategy proposed in this paper can solve the harmonic problem well.
