Permanente magnet synchronous machines (PMSM) are increasingly adopted in the wind power industry due to their higher torque capacity and power density. Multi-pole PMSM has the potential to operate as gear-less wind turbine generator system with direct drive construction. To realize a multi-megawatt wind turbine, state-of-the-art technology adopts paralleled two-level converters, as shown in Fig. 1. The In this project, please conduct a simulation case study of a PMSM based wind turbine generator system using the system configuration shown in Fig.
1. Specifically, pay attention to the following aspects:
- PMSM control strategy.
- PWM of each converters: third-order harmonic injected sinusoidal PWM (SPWM) with carrier frequency of 2700Hz. The carriers of the paralleled converters are synchronized.
- Determine system parameters, e.g. DC link voltage, inductance of L1, L2, L1g, and L2g, etc.
- Show simulation results under normal operation.
- Assume the inductance at grid side (L1g and L2g) have 10% mismatch. 1). Observe simulation results and briefly explain the phenomenon. 2). Develop a control strategy for grid side converters to address the observed phenomenon.
- Recommend a control strategy during a grid fault and run simulations.
