Cascaded H bridge of STATCOM
ivecurrent Figure 9 is the maximum reactive current transition from the emotional to the maximum value of DC voltage capacitive changes. DC voltage jump after a bifurcation, because the controlled object is the voltage, the conduction angle sorting is 28O24O> 200】 60l2O00. O50.10.150.20.250.3t / s Figure 9, the current changes from inductive to capacitive DC voltages Fig. 9DCvoltage'Schangingwheninductivecurrentjumpstocapacitive benchmark for judging the minimum voltage, it is possible near the bridge at the target rate of charging and discharging lead to inconsistency between the DC voltage is generated. Simulation results show little difference between the DC voltage does not affect the output current harmonic content. Steady state by the previous analysis shows that the system must absorb active power, the minimum voltage of the bridge at this time conduction angle a certain maximum, the maximum absorbed power is also certain. Differences in steady-state DC voltage will not increase,[link widoczny dla zalogowanych], and will eliminate the dynamic large. SVG by simulation analysis of voltage and current harmonics are mainly found in the third harmonic, if the SVG form of access into △, then there is no third harmonic output line current harmonic content will be greatly reduced. 5 Conclusion H bridge DC voltage ranging from Cascade Bridge SVG main advantage is that less and does not require serial magnetic interface. From the theoretical analysis and experimental results verify both its operating characteristics,[link widoczny dla zalogowanych], control methods that can make a reasonable SVG meet the requirements. Of the cascade inverter DC voltage is not easy to balance problems, can also be resolved by software. References: EliPengFz, LaiJS, MckeeverJW, eta1.
