Novel Green Plug switched filter schemes based on Multi Objective Genetic algorithm MOGA for single phase induction motors

Abstract

The paper presents a family of novel switched smart filter compensated devices using Green Plug Smart Filter Soft Starter GP-SF-SS devices for small single phase induction motors. GP-SF-SS devices are equipped with a dynamic online error driven optimally tuned controller that ensures improved power factor, reduced feeder losses, stabilized voltage, minimal current ripples and efficient energy utilization/conservation with minimal impact on the host electric grid security and reliability. The family of GP-SF-SS schemes is intended for use with residential / commercial motor drives used in water pumping, ventilation, air conditioning, compressors, refrigeration applications. The outcome is improved power quality, efficient utilization and reduced KWh energy consumption. The family of Green Plugs, Smart Filters and Soft Starters are all low cost additions with an estimated cost of $10–15/KVA ratings and with payback periods ratings from 6–12 months at most.
