双向逆变器的并网控制策略研究

介绍了一种基于纯交流母线供电的风光柴互补发电系统中蓄电池充放电的装置,即双向逆变器,并对它的并网运行模式进行了深入研究,阐述了它在并网运行模式下的拓扑结构、工作原理、控制方案.在此基础上设计出一台2 kW实验样机,实验结果表明该双向逆变器在并网模式下可以实现能量的双向流动,具有较高的功率因数,满足并网运行要求.

Study of grid-connected control strategy of bi-directional inverter

This paper introduces a device,called bi-directional inverter,which can be used in charging or discharging storage battery in a wind-solar-diesel hybrid power system based on pure AC bus,makes further study into its grid-connected operation mode and describes its topology structure,operation principle and control scheme in grid-connected operation mode.On this basis,a 2 kW experimental prototype has been designed.The experimental results show that the bi-directional inverter can achieve bi-directional flow ...
