Power efficient PID controller of wind driven induction generation single-phase induction motors for electric energy saving applications

Abstract

The paper presents a novel self adjusting wind energy utilization scheme using a modified single phase operation of the three phase induction generator supplemented by a voltage stabilization switched filter compensation scheme. The series-parallel switched capacitor filter scheme is controlled by a dynamic Particle Swarm Optimization PSO error driven self adjusting controller to ensure voltage stabilization, minimum impact of the electric load excursions and wind variations on terminal voltage. The paper presents a family of novel switched smart filter compensated devices using Green Plug Filter Compensator GPFC devices for small single phase induction motors. The GPFC 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.
