摘要
由于电力系统自身的脆弱性和抗干扰性能,以及光伏系统的波动、间歇性和随机特性,使得电力系统的稳定性受到了极大的影响。以此为条件,建立分布式光伏并网数学模型,研究分布式光伏并网对电网线损、电压偏差及继电保护等方面的影响。文章对光伏能源板并网技术进行了深入的研究,为光伏能源板并网技术的发展和应用奠定了理论基础。
Due to the vulnerability and anti-interference performance of the power system itself,as well as the fluctuation,intermittent and random characteristics of the photovoltaic system,the stability of the power system has been greatly affected.Under this condition,the mathematical model of distributed photovoltaic grid-connected is established,and the influence of distributed photovoltaic grid-connected on line loss,voltage deviation and relay protection is studied.This project has conducted in-depth research on photovoltaic energy panel grid technology,which lays a theoretical foundation for the development and application of photovoltaic energypanelgrid technology.
