Abstract

Grid-Connected power conditioning system (PCS) is widely used for distributed generation system. In Grid-Connected PCS, the LC filter is essential to reduce the current harmonics injected to the grid. In this paper adequate inductor core materials are selected to analyze the performance of 10kW Grid-Connected Photovoltaic (PV) PCS. Core materials can be classified into three groups: power core, sheet core and ferrite core. For the experiment, Fe-3%Si core, Fe-6.5%Si (Super core) and Mega Flux core were chosen as a filter inductor core. Optimal condition for each inductor core is determined by the efficiency and THD.

电感芯材料特性变化对10kW光伏并网电力调节系统性能的影响
并网电力调节系统在分布式发电系统中得到了广泛的应用。在并网PCS中,LC滤波器对于减少注入电网的电流谐波至关重要。本文选取合适的电感芯材料,对10kW光伏并网PCS的性能进行了分析。铁芯材料可分为三大类:功率铁芯、片状铁芯和铁氧体铁芯。实验选用Fe-3%Si铁芯、Fe-6.5%Si(超级铁芯)和Mega Flux铁芯作为滤波电感铁芯。每个电感芯的最佳状态由效率和THD决定。
