摘要:
针对LCL 滤波器虽然电感量较小并对高频谐波电流具有更好衰减效果,但一直存在谐振的问题,提出在三相系统中引入网侧电感电流控制环,修正逆变侧电感电流给定的有源阻尼型控制方法,且从系统效率的角度,有源阻尼的方法优于加入无源阻尼。该方法除了能有效抑制LCL 谐振,同时可改善入网电流的品质。不同于以跟踪工频给定为目标的光伏并网逆变器,有源电力滤波器( APF) 更看重谐波电流的控制,对控制器的设计提出了更高的要求。通过在网侧电流修正环中引入谐振控制,提升系统的补偿性能。最后通过仿真和实验,证明了该控制方法的有效性。
Abstract:
Although LCL can be designed with smaller inductance value and can better damp higher-order harmonics,LCL may also cause resonance. For three phase system,an active damping method was proposed by introducing a grid-side inductor current control loop to correct the inverter side inductor current reference. This controller is superior to the passive damping one from the point of system efficiency. By this resonance damping controller the performance of the current that is injected into the grid is also improved.Different from the photovoltaic inverter which is to track sinusoidal reference with mains frequency,the active power filter ( APF) is to track distorted reference with many harmonics and this requires more challenging controller design. By introducing resonant controller in the correction loop,APF system performance is promoted,and the effectiveness of the controller is verified through simulations and experiments.
