Need for Wind Turbine Models • Over the last decade wind turbine capacity has grown to the point where they need to be explicitly considered in system-wide transient stability studies Growth in US Wind Capacity http://www.awea.org/publications/reports/AWEA-Annual-Wind-Report-2009.pdf T12: Wind Turbine © 2012 PowerWorld Corporation 2
Wind Turbine Modeling • A wind farm usually consists of many small turbines in a collector system • Each turbine’s voltage is usually less than 1 kV (usually 600 V) with a step-up transformer (usually to 34.5 kV) • Usually, the wind farm is modeled in aggregate, but how accurate such aggregate models are is an open question • PowerWorld Simulator provides support of each of the four major types of wind turbine models used in transient stability studies – Type 1: Induction generator with fixed rotor resistance – Type 2: Induction generators with variable rotor resistance – Type 3: Doubly-fed induction generators – Type 4: Full converter generators • New wind turbines are either Type 3 or Type 4 T12: Wind Turbine © 2012 PowerWorld Corporation 3
