摘　　要：提出了一种特殊的适用于大功率太阳能并网发电厂的两级并网系统设计方案。前级采用Boost升压电路等进行太阳能电池板最大功率的追踪,后级使用高功率因数逆变器进行逆变并网,并且采用快速关断以及冗余技术,提高了系统的可靠性;此外,还分析了该系统的使用环境、优势和限制的所在。A two-stage utility grid connect was designed to fitapply for high-power solar energy combined to grid.The preceding stage traces the max power point with Boost converter,and the Boost converter’s work mode was analyzed.The backward stage was high power factor inverter.The fast turn-off and redundancy technology could improve the system reliability.In addition,the environmental conditions,superiority and limiting of the sys-tem was analyzed.
