摘　　要：现有并网系统中传统LCL滤波器有效解决了电流谐振问题,而分裂电容型LCL滤波器则进一步降低了阻尼电阻的功率损耗。针对分裂电容型LCL滤波器的参数配置繁琐、计算密集、准确性低等问题,提出一种基于NSGAⅢ多目标优化算法来设计滤波器的参数,并给出了滤波器参数寻优的实现流程。仿真结果表明,该方法不仅改善了滤波性能和系统稳定性,还降低了功率损耗,大大降低了设计过程对经验的依赖,滤波器参数设计更加具有普适性。In existing grid-connected systems,traditional LCL filters effectively solve the problem of current resonance,while split-capacitor LCL filters further reduce power loss in damping resistors.Aim at the problems that split-capacitor LCL filters exists complex parameter configuration,computational intensity and low accuracy associated.In this paper,a filter parameter design approach based on the NSGA III multi-objective optimization algorithm is proposed,and the realization flow of filter parameter optimization is also given.The simulation results indicate that the method not only improves filtering performance and system stability but also reduces power loss,greatly reduces the dependence on experience in the design process,and the filter parameter design is more universal.
