The Design Of Wind And Solar Power Supply System

Energy is the cornerstone of national economic development and social civilization progress,and energy sustainable development is one of the important guarantee for sustainable development of human society.In our country,solar and wind power are relatively affluent,combining the two,and its power supply advantage is more advantageous than a single energy supply.At present,the conversion efficiency of the landscape complementary power supply system is relatively low,and the maximum power tracking technology is used to improve the efficiency of the system,and the design of this project is to study the complementary power supply system.The power supply system uses the modular design thinking,studies the function of each part circuit implementation method,chose the LPC1114 chip as the core,including solar power circuit parts,wind power generation circuit,battery charging and discharging part,and a series of auxiliary circuit such as voltage sampling circuit,current sampling circuit,boost circuit,rectifier,filter circuit,etc.In order to obtain high charging efficiency,the MPPT control process of wind and solar power generation is an important part,and the maximum power tracking can improve the conversion rate of energy.This paper studies the effective algorithm of the maximum power tracking of a landscape complementary power supply system with high tracking speed and high real-time performance.Finally,using MATLAB/Simulink for modeling and simulation,the simulation results show that the project design scheme is effective and feasible.
