| 摘 要： | 针对大容量非线性负载的谐波抑制问题,依据模块化技术、N 1冗余技术以及非线性环节稳定性理论,提出了一种模块化并联有源电力滤波器,研究了模块化结构、N 1冗余控制、负载电流检测方案以及并联均流策略,对多模块并联系统进行了建模和稳定性研究,设计并实现了基于两台有源电力滤波器模块的并联补偿系统.实验证明,模块化并联补偿方案是可行性的,每台有源电力滤波器模块的输出电流相等,并联补偿系统可以将典型(电流源型)谐波源的网侧电流畸变率降低到补偿前的1/5以下.

| Abstract: | Aiming at solving the harmonic of large capacity nonlinear load and at the theoretical basis of modularization,redundancy technique and stability theory of nonlinear system,the design of multi-modular shunt active power filter(APF) is presented.Multi-modular topology,N 1 redundancy,current sharing scheme,modeling and stability analysis are studied.Finally,it is verified by experiments based on two APF modules in parallel connection that the output currents of all modules are the same and the THD of power grid current can be lowered to 1/5 of uncompensated level when harmonic current source has to be compensated by multi-modular shunt APF system. |
