Enhancing Performance and Energy Efficiency of Diesel-Induction Generator System under Linear and Nonlinear Load Conditions

This paper focuses to Enhance the economic fuel saving technique for Wind-Diesel hybrid dispersed power generating during unbalanced nonlinear loading conditions, this isolated unbalanced load create the undesirable effects like voltage fluctuations, frequency deviations, pulsating torque, increase the harmonic pollution factors and other effects can lead to the generation of energy losses in both diesel-driven alternators and wind-driven induction generators. An Induction Generator (IG) is typically powered by a wind turbine, while a synchronous generator is driven by a diesel engine. The fuel consumption is increase from its normal value followed by pulsating electromagnetic torque due to sharing of unbalanced and non-sinusoidal current of consumer loads. Therefore, it is essential to appropriately distribute the load current between the power sources and the consumer load. However, a significant amount of non-sinusoidal and unbalanced current is being distributed to the consumer loads. This phenomenon can result in decreased fuel consumption and optimal cost savings. The integration of parallel wind-driven induction generators can effectively reduce fuel consumption in engine-driven generators by managing the distribution of unbalanced and non-linear loads. The proposed system model has been developed and implement through PSCAD-EMTDC simulation package and also evaluate the simulation results through experimental set up.
