Description
Summary:Aiming at the topology structure and power unit structure of Cascaded High Voltage Inverter(CAS-HVI),a simulation platform based on VVVF was installed by using Simulink to build power unit group, phase-shifting transformer systems and PWM generator subsystem based on Carrier-based Phase-shifting SPWM (CPS-SPWM) modulation principle. In addition,the platform was utilized to qualitatively analyze the change of input current, bus voltage, bus current and output current of the power unit under abruptly increasing or decreasing load, and the state of the power unit was analyzed in the case of interphase short circuit fault. It shows that the simulation platform can not only improve safety of CAS-HVI systems developing process and efficiency, and also reduce developing cost. Meanwhile, it reveals the efficiency and convenience of this simulation technology.
