Application of matrix converter in wind energy conversion system employing synchronous generator

Renewable energy is catching people´s attention with increasing global energy consumption and noticeable environmental pollution across the globe. The increasing size of wind farms requires power system stability analysis including dynamic wind generator models. For turbines above 1 MW, doubly-fed induction machines are the most widely used concept. However, direct-drive wind generators based on converter-driven synchronous generator concepts have reached considerable market penetration. This paper presents converter driven synchronous generator models of various order that can be used for simulating transients and dynamics in a very wide time range. The matrix converter is used for conversion of variable voltage to a constant value that can be connected to a grid.
