Abstract

With the rapid development of the global economy, solar photovoltaic power generation has attracted wide attention all over the world. With the rapid development of all kinds of new energy in the world, photovoltaic power generation has a huge international market and broad prospects for development. This paper analyzes the feasibility of the distributed photovoltaic power generation system in this city, based on the actual situation of a photovoltaic power generation project in a certain place. Through the type selection of a variety of solar cell groups, component installation, operation mode selection, and inverter selection, Therefore, a more reasonable PV module and electrical part(The design and study of the first part, the two part of the electrical system and the lightning protection measures) are designed. The research shows that the comprehensive value of photovoltaic power is very high, and the distributed photovoltaic power station can be built in the areas where the geographical conditions are suitable and the light is sufficient. After the completion of the above power generation projects, the local solar energy resources will be fundamentally transformed into economic advantages.

Highlights

  • With the rapid development of the global economy, the demand for electricity in every country in the world is increasing year by year

  • The core technology of photo-voltaic power generation has been slowly mature track, the rapid development of solar photo-voltaic power generation technology to the national economy played a crucial role in the global energy highly stressful situations, this technology can meet the people of new energy demand

  • According to the characteristics of the project, the 50kW series inverter is used in this photo-voltaic power generation project, and the inverter should have the anti PID device

Summary

Introduction

With the rapid development of the global economy, the demand for electricity in every country in the world is increasing year by year. The core technology of photo-voltaic power generation has been slowly mature track, the rapid development of solar photo-voltaic power generation technology to the national economy played a crucial role in the global energy highly stressful situations, this technology can meet the people of new energy demand. Taking a city in China as an example, the city is one of the most developed areas of China's solar energy resources. Solar energy can be sustained output, and fully meet the necessary conditions for solar energy development. The city carries out the planning and construction of the photo-voltaic power plant project, which will vigorously promote the high speed development of the local distributed photo-voltaic power plant construction [2]
