光伏发电并网逆变器控制系统设计

Design of the Control System for Grid-connected Inverter of Photovoltaic Power Generation

随着光伏并网系统的发展,光伏并网系统不再是一个单独的并网逆变器,而是由多个部分组成,通过控制策略,使得系统能够工作在一个相互协调控制的状态。光伏并网系统是通过光伏阵列将光信号转换为直流电信号,之后经过光伏逆变器,将直流电转化为电网相匹配的交流电后接入电网。

With the development of the PV grid-con-nected system,the PV grid-connected system is no longer a single grid-connected inverter,but composed with several components controlled by control strategies,enabling the system to work in a state of coordinated control with each other.PV grid-connected system is a PV array that converts light signals into DC signals,and then,it goes through a PV inverter,in which the DC power is converted into AC power that is compatible with the power grid and is connected to the power grid.
