摘要
在能源互联网发展背景下,近年来逐渐出现将城市轨道交通与光伏发电系统相结合的工程实例。为分析光伏发电系统在城市轨道交通中应用的可行性,对光伏发电系统接入城市轨道交通供电系统展开了理论分析和仿真验证。首先,对光伏发电系统在城市轨道交通供电系统中的应用特点和光伏发电系统的发电量估算进行了简要概述;然后,针对光伏发电系统并入城市轨道交通供电系统AC35 kV侧,基于MATLAB&Simulink搭建了仿真模型,并对比分析了光伏发电系统接入前、后供电系统的电能质量变化,结果表明,光伏发电系统对城市轨道交通供电系统造成的无功及谐波影响较小,具有良好的适应性。
With the development of the"Energy-internet"in recent years,there have been cases of urban rail transit integrated with PV power generation system.In order to analyze the feasibility of PV power generation systems connected to urban rail transit power sypply system,theoretical analysis and simulation verification were carried out in this article.A brief overview of characteristics of PV applications in urban rail transit power supply system and the estimation of power generation were porposed.Aiming at the AC35 kV side of PV integrated urban rail trarsit power supply system,a simulation model is built based on MATLAB/Simulink,and the power quality changes before and after connection are compared.The results show that the PV power generation system has good adaptability and small impact of reactive power and harmonics on the urban rail transit power supply system.
