Effective Single Phase Induction Motor Controller Based On Multi Objective Genetic Algorithm MOGA Using Green Plug Compensator Schemes

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 used in air-conditioning, ventilation and water pumping. GP-SFSS devices are equipped with a dynamic online error driven optimally tuned modified PID 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 Green Energy devices and filters is based on concept of avoiding cyclical variations and transients in voltage and current to ensure uniform quasi steady state power and energy load demand. 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.
