| Summary: | This paper presents the improvement of power quality, mainly harmonic during soft starting of induction motor. Soft starters are used to avoid high inrush current and to achieve smooth starting of large induction motors. But, this takes harmonic-rich current especially while operating at large firing angles. AC voltage controller is used as soft starters in induction motors. Different types of filters such as series passive power filter (SPPF), shunt active power filter (SAPF), and shunt hybrid power filter (SHPF) are used in three-phase AC voltage controller. The effect of inserting various types of filter is to improve harmonic and reactive power compensation during soft starting. The advantages of proposed method are its simplicity, accuracy and fast response. Simulation is carried out using PSIM which has user friendly approach. |
