Wind Turbine Modeling • Types 1 and 2- Induction machine models, stator windings are connected to the rest of the network, rotor currents are induced by the relative motion between the rotating magnetic field due to the stator currents and the rotor • Slip is the difference between the synchronous speed and the rotor speed, defined using motor convention as S = n s − n n • Synchronous speed is n s an rotor speed is n r , per unit s r + V t - R a I jX a jX m jX 1 R 1 /S Equivalent circuit for a single cage induction machine T12: Wind Turbine Glover, Sarma, Overbye, Power System Analysis and Design © 2012 PowerWorld Corporation 8
Type 1 Wind Model- WT1G Power Speed Curve Real Power Type 1 generators usually operate with a small negative slip since the wind turbine causes the machine to spin slightly faster than synchronous speed T12: Wind Turbine 2.8 2.6 2.4 2.2 2 1.8 1.6 1.4 1.2 1 0.8 0.6 0.4 0.2 0 -0.2 -0.4 -0.6 -0.8 -1 -1.2 -1.4 -1.6 -1.8 -2 -2.2 -2.4 -2.6 -2.8 Real Power -0.95-0.9-0.85-0.8-0.75-0.7-0.65-0.6-0.55-0.5-0.45-0.4-0.35-0.3-0.25-0.2-0.15-0.1-0.05 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 0.45 0.5 0.55 0.6 0.65 0.7 0.75 0.8 0.85 0.9 0.95 Slip Real Pow er © 2012 PowerWorld Corporation 1 Values are calculated between a Slip of -1 and 1 9
