并网型光伏电站工作原理及其一二次设备配置原则

Working Principle of the Grid-connected Photovoltaic Power Station and Primary and Secondary Device Configuration Principles

世界光伏产业和市场在严峻的能源形势和人类生态环境形势的压力下,进入到了快速发展时期,并网光伏电站逐年增加。以光伏发电并网系统为研究对象,对其工作原理进行了详细介绍和分析,并结合《地区电源并网工程继电保护及安全自动装置配置规范》要求对石家庄地区35 kV并网型光伏电站一二次设备配置情况进行了说明,以其为今后大规模光伏并网发电提供参考依据。

The world photovohaic （PV） industry and market entered a period of fast development under the pressure of severe energy and human ecology environment situation. The grid-connected PV stations increase every year. In this paper, grid-connected PV power generation system is taken as the research object, the working principle is introduced and analyzed, and combined with the configura- tion rules of engineering relay protection and safety automatic device in the power grid to illustrate the primary and second equipment configuration of 35 kV grid-connected PV power station in Shijiazhuang area, which can provide reference basis for future large-scale PV grid power generation.
