分布式光伏电站电气一次设计研究

Research on Electrical Primary Design of Distributed Photovoltaic Power Station

光伏发电是目前最具开发价值的可再生能源之一,随着全球经济的快速发展和传统石化能源的日趋衰竭,分布式光伏发电的研究和实施在不断深化。以实际项目为设计案例,从电力接入系统、电气主接线、主要电气设备选择、电气设备布置以及防雷接地等几个方面进行分析,确定光伏电站开关站35 kV电气一次设计方案,为其他类似分布式光伏并网发电项目提供理论基础。

Photovoltaic power generation is one of the most valuable renewable energy sources.With the rapid development of the global economy and the gradual depletion of traditional petrochemical energy,the research and implementation of distributed photovoltaic power generation are deepening.Taking the actual project as the design case,this paper analyzes the power access system,the main electrical wiring,the selection of main electrical equipment,the layout of electrical equipment and the lightning protection grounding,and determines the primary electrical design scheme of 35 kV switch station of photovoltaic power station,which provides a theoretical basis for other similar distributed photovoltaic grid-connected power generation projects.
