强化電力潮流動態模型控制方法

The present invention relates to a method for controlling a unified power flow dynamic model. A series connection inverter, a parallel connection inverter and a direct current (DC) coupling capacitor are built up at two buses of a power system transmission circuit respectively; by use of the series connection inverter, the d axial current may be utilized to regulate the real work of the transmission circuit, and the q axial current may be utilized to regulate the virtual work of the transmission circuit; by use of the parallel connection inverter, the d axial current may be utilized to regulate the voltage of the UPFC DC coupling capacitor, and the q axial current may be utilized to regulate the s transmission end bus current; the UPFC DC coupling capacitor is applied to maintain the voltage of the transmission current; and then the regulated current is sent to the power use system.
