摘  要:
光伏电池输出功率易受光照强度和外界温度的影响,需采用最大功率点跟踪电路,才能使光伏电池始终输出最大功率,是提高光伏电池效率的重要手段。本文通过分析比较传统电导增量方法,提出一种新型双并联Boost电路的功率预测改进电导增量法最大功率跟踪策略。利用Matlab/Simulink软件进行仿真建模与分析,表明本文所提出的方法跟踪速度更快、稳态性能更好、纹波系数更小,减小振荡的同时又能避免发生误判,可有效实现对太阳能发电系统输出特性的优化,对于光伏发电系统有重要的参考意义。

摘  要:
Output power of photovoltaic cell is easily affected by light intensity and ambient temperature.Photovoltaic maximum power point tracking circuit should be used to make the maximum output power of photovoltaic cell.Through the analysis and comparison of the traditional incremental conductance method,a new type of double parallel Boost power circuit improved prediction of incremental conductance maximum power tracking strategy was proposed.Based on Matlab/Simulink simulation and analysis,the proposed method has higher tracking accuracy,better steady state performance,and the ripple coefficient is smaller.It can also reduce the oscillation and can avoid the miscarriage of justice.The output characteristics of the solar power system can be optimized effectively.This method has important reference value for the photovoltaic power generation system.
