摘　　要：针对逆变器并联系统的系统环流,提出了一种基于解耦控制的逆变器并联系统均流控制策略,对各逆变器设置一个独立的逆变电压调整电路,通过调节逆变电压使各逆变器的输出电压均相等,同时采用电压外环、电感电流内环的双闭环控制方式来达到均分负载电流,即实现均流控制的目的。因各逆变电压调整电路独立控制,因而完成了逆变器并联系统均流控制的解耦。在Matlab/Simulink下建立两台逆变器并联系统仿真模型,仿真结果证实解耦控制下系统均流性能较为理想,系统环流较小。In view of the system circulation in inverter parallel system, a control strategy for inverter parallel system based on decoupling control is presented, setting up an independent inverter voltage adjust circuit for each inverter, the inverter output voltage are equal by adjusting the inverter voltage, at the same time, use the double closed loop control method of voltage outer ring and inductance current inner ring to divide the load current, namely achieve the purpose of flow control. because of the independent control of inverter voltage regulation circuit, thus achieved decoupling of flow control in inverter parallel system. Simulation experiment is carried out under the Matlab/Simulink, and the simulation results confirmed that the decoupling control of parallel system has good flow ability and system circulation is smaller.
