摘要
随着直流微电网和智能电网技术的快速发展,光伏逆变器不再成为光伏并网系统必不可少的组成部分。与交流微电网相比,直流微电网的供电可靠性高,抗干扰能力强。介绍了以电力电子变压器为核心设备的光伏中压直流并网系统,实现了光伏系统直流并网。并在RTDS实时数字仿真平台建模进行系统动态与稳态运行功能验证。
With the rapid development of DC microgrid and smart grid technology,photovoltaic inverter is no longer an essential part of photovoltaic grid connected system.Compared with AC microgrid,DC microgrid has high power supply reliability and strong anti-interference ability.This paper introduces the photovoltaic medium voltage DC grid connection system with power electronic transformer as the core equipment,which realizes the DC grid connection of photovoltaic system.The dynamic and steady-state operation functions of the system are verified by modeling on RTDS real-time digital simulation platform.
