Exploration And Application Of Typical Design Of Distributed Photovoltaic Power Generation Scheme

With the advancement of distributed photovoltaic power generation technology,industrial upgrading,and rapid expansion of market scale,photovoltaic power generation costs continue to decline globally.The application of distributed photovoltaic power generation is becoming more and more common.Currently,the most widely used distributed photovoltaic power generation equipment is generally on the roof of buildings.Such distributed photovoltaic power generation equipment needs to access the public net work to ensure the reliability of the power supply of the distributed photovoltaic power generation system to the user and the quality of the power consumption.In order to improve the efficiency of distributed photovoltaic connection and provide users with professional and reliable photovoltaic power generation solutions,It is a research work with a wide range of application markets and prospects.This paper conducts exploratory research on distributed photovoltaic power generation solutions,and studies related literatures of domestic networks,fully understanding the development history and development status of photovoltaic power generation.Sum marize the related advantages and disadvantages of photovoltaic power generation.In order to reduce the impact on power grid planning and operation after photovoltaic net works are connected,we need to speed up the investment time for customers to handle photovoltaic power generation projects and shorten the processing process.Finally,after the above study and research,through the step-by-step implementation of the hair,brainstorming method and on the basis of full investigation,the factor model required for the photovoltaic power generation scheme was established,including the project overview and design.The design of the distributed photovoltaic system is proposed by the design factors such as the scope,the grid situation of the project location,A typical design factor library is established,and the necessity factor of the typical design is summarized from the factor database.The three projects of Self-use,self-use balance on the Internet,dual park self-use are the main research objects.Using the distributed photovoltaic typical design scheme proposed in this paper,the project overview and design scope are analyzed first.And give the corresponding data.Then analyze and investigate the general situation of the 66 kV power grid and the 10 kV power supply line in the project area,and further understand the analysis of user load and power balance to ensure the feasibility of distributed photovoltaic power generation.Finally,the photovoltaic system project access system scheme is proposed.Throug h the collection and analysis of design factors,the power generation solutions of these three projects were successfully proposed to provide customers with accurate and reliable solution design.It also verifies the scientificity and generalization of typical design schemes.
