分析了一种基于矢量效用观测器的逆变器-电网同步新算法，并利用Park矢量变换实现了瞬时有功和无功功率的解耦调节。在时域和变换域中都考虑了电网谐波的影响。基于数字信号处理器的算法在模拟三相并网逆变器的电流源矢量控制中实现，在需要时保证单位功率因数。多次仿真显示了所提出的公用设施观测器的性能以及三相并网逆变器的控制。
The analysis of a novel algorithm based vector utility observer for inverter-grid synchronization is carried out, whereas the decoupled regulation of the instantaneous active and reactive power is achieved by using the Park vector transformation. The effect of the grid harmonics is considered, both in time domain and in transform domain. The digital signal processor based algorithm is implemented in the current source vector control of a simulated 3-phase grid-connected inverter, guaranteeing a unitary power factor if it is desired. Several simulations show the performance of the utility observer proposed, as well as the control of the 3-phase grid-connected inverter.
