Zusammenfassung: | The utility model discloses a controlled rapid response phase-splitting control device for dynamic reactive power compensation system. The phase-splitting control device comprises a three-phase voltage acquisition means (1), a three-phase current acquisition means (2), an MCR voltage acquisition means (3) and an MCR current acquisition means (4), wherein the three-phase voltage acquisition means (1), the three-phase current acquisition means (2), the MCR voltage acquisition means (3) and the MCR current acquisition means (4) are connected with the input end of a DSP controller (5) respectively, and the output end of the DSP controller (5) is in connection with an MCR (7) through a thyristor driver (6). With the phase-splitting control device, the total resistance of a current system is calculated, MCR output resistance is calculated based on Stan Clements' theory, and the rapid response feature of the MCR is taken advantage of so that three-phase imbalance resulted from an asymmetric load may be effectively c |
