Aiming at the status quo of ASVG developed at home and abroad, this paper introduces a theory and method of AS VG device based on IGBT intelligent module and adopting self-tuning algorithm.In the realization of system structure, The circuit adopts intelligent module IPM based on IGBT to form a three-phase bridge three-level converter. The controller adopts double CPU structure and takes DSP (TMSF240) as the main controller, whose tasks are sampling, calculation and real-time control. The 80C196 As auxiliary controller, it specially deals with external keyboard input, data display inquiry and communication with host computer.In the control strategy of the device, indirect current control and self-tuning self-tuning PID algorithm are adopted in order to realize the dynamic reactive power compensation The experimental results show that the device has fast response, high precision, simple structure and easy maintenance.
