Validity Range of Wind Turbine Models

Abstract

In this paper, the focus is on fundamental frequency simulations, also known as electromechanical transient simulations. In this type of simulation, the network is represented as an impedance matrix and only the fundamental frequency component of voltages and currents is taken into account in order to reduce the computation time. This simulation approach is mainly used for voltage and angle stability investigations. Models of wind turbine generating systems, which match the fundamental frequency simulation approach, are presented and their responses are compared with an electromagnetic transient model.
