电网友好型分布式光伏发电系统

Distributed Grid Friendly Distributed Photovoltaic Power Generation System

分布式光伏发电系统在国内政策扶持下进入了快速发展期。因此,分析山东省广饶县农村分布式发电系统的发展现状,特别是发展中出现的光伏发电系统公共连接点电压过高、区域微网内潮流逆流等问题进行深入研究,以并网系统发展初期的现状为例,从远程自动控制逆变器的有功与无功功率的输出角度提出解决方案,同时设计出电网友好型分布式光伏发电系统,以避免分布式发电并网系统公共连接点电压升高或过电压产生的潮流逆流问题。

The distributed photovoltaic power generation system has entered a rapid development period under the support of domestic policy. In this paper, the current situation of the development of rural areas in Shandong County of Guangrao Province in the distributed generation system, especially in-depth study of photovoltaic power generation system and the common connection point for high voltage microgrid in countercurrent flow of regional problems in development, to the status quo of the early development of grid system as an example, put forward the solution from the remote automatic control of active and reactive power inverter the output of power angle, and designs the power users good type of distributed photovoltaic power system. In order to avoid the current current problem of power flow in the common connection point of the distributed generation system, the common connection point voltage or overvoltage is avoided.
