摘要:
随着反向阻断型功率开关器件和电感储能技术的发展,电流源逆变器已成为目前应用最为广泛的中压逆变器,但传统控制方案的电流源逆变器在较高的开关频率工作时,容易出现电流畸变、震荡等问题,导致电能质量降低,因此,不同控制方案是决定其性能的重要基础。文章针对光伏并网发电系统和不间断供电系统2种应用场景下的电流源逆变器优化控制问题,分析了基于比例谐振的控制方案特性,研究了控制系统的频域,并对其性能进行了仿真验证。结果表明:采用比例谐振控制的电流源逆变器,光伏发电系统中电网电流的谐波畸变率(THD)为3.22%,电流跟踪控制效果良好;不间断供电系统中,基于比例谐振控制的电流源逆变器的控制性能明显提高,公共连接点的电压波形THD为2.26%,不受非线性负载谐波的影响。
Abstract:
With the development of reverse blocked power switching devices and inductive energy storage, it is attractive to use lower power energy storage converter in distributed power generation areas. The current-source converter in the traditional control strategy works under the high switching frequency. It will result in the current distortion and oscillation and reducing power quality. Therefore, the control strategy is the basis determining the performance of the current-source converters. Taking the photovoltaic grid-connected power generation system and uninterruptible power supply (UPS) system as examples, this paper designs a proportional resonant controller control strategy for the current source inverter optimization control under these two application scenarios, and performs system frequency domain analysis. The simulation compares the traditional proportional controller. The results show that in the photovoltaic power generation system, the current source inverter adopts the proportional resonance controller and total harmonic distortion (THD) of the grid current is 3.22%, and the current tracking control effect is good, which can satisfactorily meet the power quality requirements of photovoltaic grid connection. The control performance of the proportional resonant controller is significantly higher than that of the simple fundamental frequency proportional controller. THD of the common connection point is 2.26%, which is not affected by the nonlinear load harmonics.
