基于工程用光伏模块输出方程，利用Matlab/Simulink建立一个光伏电池实用仿真模型。该模型可以模拟实际光伏模块在不同环境下的输出特性曲线。在传统的电导增量法基础上利用计算得到的步长进行最大功率点跟踪，通过仿真结果表明在外界环境剧烈变化时改进的电导增量法可以快速跟踪光伏电池的最大功率点。该文是在Matlab/Simulink中实现了梯度变步长电导增量法，且在此给出该算法的模型搭建图，并在保证仿真精度的情况下通过加入延迟模块解决了仿真中的代数环问题。

Based on output equation of engineering PV module,a practical simulation model of PV cells was established by means of Matlab/Simulink. This model can simulate the output characteristic curves of practical PV module under different en-vironments. The calculated step length is adopted to track maximum power point on the basis of the traditional incremental con-ductance method. The simulation results show that the maximum power point of photovoltaic cells can be fast tracked with the im-proved incremental conductance method as the external environment changes violently. The innovation of this paper is that the gradient variable step incremental conductance method is implemented in Matlab/Simulink,the simulation model diagram of the algorithm is presented in this paper,and the algebraic loop problem existing in simulation is solved by adding a delay module in the case of ensuring the precision.
