Real-time hybrid model of a wind turbine with doubly fed induction generator

Abstract

In recent years renewable sources have been dominating power system. The share of wind power in energy production increases year by year, which meets the need to protect the environment. Possibility of conducting, not only computer simulation, but also laboratory studies of wind turbine operation and impact on the power system and other power devices in laboratory conditions would be very useful. This article presents a method of performing real-time hybrid model of a wind turbine. The advantage of a hybrid model is the combination of the possibilities and flexibility of simulation of aerodynamic and mechanical phenomena with the electric machine, which is seen from the point of view of the grid as a real wind turbine. The originality of the presented approach is using a real-time digital model to control a power device connected to the grid. Real-time simulation is performed of aerodynamic phenomena and conversion of wind energy for a mechanical moment on the shaft, which controls via a converter of asynchronous motor driving a doubly-fed induction generator. The hybrid model allows testing wind turbines in transient conditions after disturbances not feasible with physical wind. The paper describes the concept and the structure of a wind turbine hybrid model. Components of a wind turbine hybrid model are described. The results of laboratory studies of the real-time hybrid model of a wind turbine are presented.
