Design And Implementation Of Distributed Village-level Photovoltaic Power Generation System

With the rapid development of the world economy,human demand for energy continues to increase,but the traditional use of energy is bound to aggravate environmental pollution and destruction.At the same time,the world’s proven energy is rapidly decreasing.People urgently need to develop a new type of energy to alleviate the current situation of energy shortage.Distributed photovoltaic grid-connected power generation system can not only significantly increase the power generation capacity,but also solve the energy consumption of power in the process of boosting and transportation.Because of the abundant solar energy resources and easy collection,it has a wide range of applications.This paper first introduces the research purpose,research significance and the development of technology at home and abroad.Then the key technology and grid-connected technology of village-level photovoltaic power station system are expounded,and the equivalent circuit of photovoltaic cells is analyzed in depth.Four maximum power point tracking algorithms are compared in detail,and the maximum power point tracking algorithm is focused on,and the disturbance observation method is selected as the maximum power of this project.Rate point tracking algorithm.In order to make the tracking effect better,the perturbation observation method has been partly changed according to the actual needs to make it more consistent with the actual situation of this study.In this paper,on the premise of adhering to the design principles of village-level photovoltaic power plants,the appropriate angle of the battery and the battery plate is selected.The inverter of the system is designed,and the parameters of the BOOST circuit are determined by calculation.The design of photovoltaic grid connected system.Intelligent monitoring system for power generation,energy storage and networking applications is designed and implemented,and the real-time operation monitoring of the village-level photovoltaic power station system is realized.At the end of the paper,an automatic monitoring system for the distributed village-level photovoltaic power plant system is designed,which completes the functions of data acquisition,recording and display,and realizes the real-time monitoring of the entire photovoltaic system.
