Stand-Alone Wind Power Generation using Adaline Based Integrated Electronic Load Controller

Abstract

Wind power is clean, economical and environmentally friendly. It is promising alternative electric power generation source at the time of unavailability of fossil fuel and reduces concern over the harmful effects of climate change due to excessive pollution caused by use of fossil fuels. This paper proposes the adaptive linear element (adaline) algorithm based integrated electronic load controller for an isolated windturbine-driven power generation. The adaline extracts the fundamental component of load current to control the voltage and frequency of generator with balancing loads in an integrated manner. The IELC is realized using zigzag/three single-phase transformers and a six-leg insulated-gate bipolar-transistor-based current controlled voltage-source converter, a chopper switch, and an auxiliary load on its dc bus. The generating system is modeled and simulated in MATLAB environment using Simulink and Simpower System toolboxes.
