摘要
一种基于下垂方法的不需要各单元之间控制连线的新型逆变器并联控制器,其控制算法使每个逆变器输出电压的幅值和相位分别随着其输出功率的无功分量和有功分量的增大而减小。与传统下垂方法不同,在下垂曲线的设置上使下垂斜率随着输出功率的增大而增大,保证了逆变器能在各种功率条件下都能有很好的均流效果。通过在Matlab上的仿真和试验验证,证明了这种方法的正确性。
In this paper,a novel controller for parallel operation of inverters without control interconnection based on the droop method is presented.In the droop method,the voltage amplitude and phase of each inverter will be decreased when its reactive power and active power increase.As opposed to the conventional droop method,the new method will enhance the droop parameters when the output power increase,which makes the inverter run well in parallel connection of various power condition.This method is proved to be valid from the simulation in Matlab and experimental results.
