Simulation of Machine-Side System Comprising Model Construction, Simplification, and Control Algorithm Design

The simulation of the machine-side system involves constructing system models, simplifying them, and designing control algorithms. The machine-side model of a direct-drive permanent magnet synchronous wind power generation system includes the wind turbine model, permanent magnet synchronous motor model, and machine-side PWM converter model. The mathematical models of the permanent magnet synchronous motor and machine-side PWM converter can be simplified into a single mathematical equation to streamline the block diagram construction. The controller design aims to regulate the synchronous motor speed for maximum wind energy tracking.
