| 摘要: |
| 针对光伏发电系统输出电压低、功率不稳定、电压波动等电能质量问题，提出了一种二阶低通滤波器和高增益FIBC变换器的组合结构。为了解决滤波器和变换器级联可能造成的谐振现象，设计了一种可有效抑制谐振发生的稳定器，能够在不增加系统体积重量和功率损耗的前提下，抑制系统的振荡和波形畸变。首先建立了系统的数学模型，并利用Lyapunov第一法对系统的稳定性能进行分析，证明了该方法的可行性。仿真结果验证了所提控制策略和拓扑结构的正确性和有效性。 |

| Abstract: |
| In order to solve the power quality problems, such as low voltage output, power instability and voltage fluctuation. A combined structure of two order low-pass filter and high gain FIBC converter is presented. By way of disposing the resonance phenomenon caused by the cascade of filter and converter, this paper designs a kind of stabilizer which can restrain the resonance effectively. It can suppress the oscillation and distortion of the system without increasing the volume weight and power loss of the system. Firstly, the mathematical model of the system is established. Then, the stability of the system is analyzed by using Lyapunov method, and the feasibility of the method is proved. The simulation results verify the correctness and effectiveness of the proposed control strategy and topology. |
