The Design of STATCOM Control System
The main characteristic of a multilevel inverter is able to reduce each power device voltage stress. Static Synchronous Compensator (STATCOM) is the major application of the inverter to compensate reactive power in power system. The proposed strategy is simple, high precision, fast response speed, while it has less fluctuation with the impact of load parameters, and good robust characteristics. STATCOM employing the multilevel inverter provides good performance such as enlarging capacity and decreasing even frequency harmonics, and the control of alternation working switch order based PWM can be applied in related research fields.
