Abstract

To study the components and parameters relationship between MMC - STATCOM and traditional STATCOM, the mathematical model of MMC-STATCOM is established. Then, the equivalent expressions for MMC-STATCOM module capacitance and inductance bridge arm are derived, compared with traditional STATCOM. On account of the corresponding complementary in the pulses of upper and lower bridge arm module, a carrier phase shift pulse modulation method is proposed, which simplifies the pulse generation. Also, the control strategy is designed, especially the module voltage balance control, considering the difference value of actual module voltage between the reference voltage and the direction of arm current. In the end, some simulations are done in Matlab/Simulink. The model and control method are both validated.
