Power quality improvement for industrial drives using FPGA controller-based SSD algorithm

Solar photovoltaic energy is very useful for supplying power to induction motor (IM) when used in industrial drives. In industrial drives, increased vibration occurs in the IM due to power quality (PQ) disturbances in the line voltages creating various faults. The IM vibration affect the power quality of the system and reduces its dynamic performance. An efficient controller, combination of two-stage commutation method and the social ski-driver (SSD) optimisation method is implemented to control the IM vibration. The primary goal of the field programmable gate array (FPGA) controller is to reduce IM vibration that improve the electrical power quality and the dynamic performance by employing the SSD optimised controller. The performance of the IM is analysed under various fault conditions such as voltage sag and voltage swell. The SSD optimisation algorithm is used to find and optimise control parameters such as speed, torque, flux linkage, and current in order to provide a better solution to vibration problems. The drive for the IM is commutated at fundamental frequency which reduce the inverter switching losses. The proposed method is implemented in hardware. The efficiency, vibration and faults are compared with particle swarm optimisation and gravitational search algorithm. The proposed method achieved 95.6% efficiency and high reduction in vibration level of 2.45–2.78% for various PQ disturbances.
