| 中文摘要 |
| 由于分布式电源逆变并网发电与有源电力滤波器(active power filter, APF)在结构功能上具有相似性, 本文提出了结合绿色分布式电源的有源电力滤波器拓扑结构, 这种结构使APF除了能够滤除谐波外, 还可以向负载供能, 拓展了APF的应用范围, 有利于电网的绿化和供能的多元化. 分布式电源通过逆变升压整流来维持APF直流侧的电容电压的稳定, 而不需要消耗电网中的能量. 针对畸变电压的工况, 设计了自适应dq检测算法; 在APF控制上采用了自适应模糊控制的策略, 不仅能快速跟踪谐波电流, 而且具有较强的鲁棒性. 仿真结果验证了该系统设计的可行性和可靠性, 证明了本文所提算法的有效性和正确性. |
| 英文摘要 |
| Distributed generators connected to the grid by inverter are similar to active power filters (APF) in structure and function. We propose the combination of APF and the green distributed generation (DG), which not only compensates the system harmonic currents but also supplies power energy to the loads when the grid power is interrupted. It is also beneficial to the greening of power grid and the diversification of power supply. The energy from the DG is utilized to maintain the DC-link capacitor voltage by inverting, boosting and rectifying. To deal with the harmonic voltage, an adaptive dq harmonic detection method is designed. Based on the detected reference harmonic currents, an adaptive fuzzy controller is applied to rapidly and precisely track the reference harmonics. Simulation results in MATLAB demonstrate the reliability and feasibility of the above mentioned control strategy. |
