摘要
针对逆变器电流环的有功电流和无功电流存在耦合的情况,文中采用电流的解耦控制,达到独立控制逆变器的有功功率和无功功率;针对逆变器直流侧电压容易波动,文中采用双环控制,稳定逆变器直流侧的电压。搭建了MA-TALAB/SIMULINK系统仿真实验平台,通过间歇性能源输入逆变器功率变化的实验,验证了该逆变器能独立控制输出的有功功率和无功功率,并且保证了直流侧电压的稳定。
Based on the coupling between the active current and reactive current of current loop of inverter,a decoupling control is adapted to achieve independent control of active and reactive power of the inverter.For the inverter DC side voltage unsteady,a voltage dual-loop control is used to keep inverter DC side voltage stability.By using MATALAB/SIMULINK system simulation testing and the experiment inverter power change active and reactive power of the inverter controlled independently was verified,and then the stability of DC side voltage can be kept.
