摘要
首先对风力发电系统背靠背变流器中的逆变器模型及其单周期控制(OCC)进行原理推导,然后在Matlab7.1/Simulink仿真环境下对单周期控制的并网逆变器(GCI)进行了仿真,最后在实验室搭建的风力发电实验平台上对其进行了验证,结果证明单周期控制并网逆变器能够工作在单位功率因数下,并可减少对电网的谐波污染。
In this paper, the principle of one-cycle controlled （OCC） grid-connected inverter in back-to-back converter is derived firstly. Then the simulation model is built in Matlab7.1/Simulink environment. An experiment is done to verify the advantages of OCC grid-connected inverter. The results of the simulation and experiment show that OCC grid-connected inverter can work in the power factor and decrease the current pollution of the grid.
