Fault-Tolerant Control Strategy Based on Multi-Phase Wind Power System

Abstract

Abstract: Owing to their characteristics of large torque, low torque ripple, and high fault tolerance, multi-phase motors are especially suitable for low-speed high-power application scenarios such as wind power systems. This paper proposes a wind power system based on multi-phase direct-drive permanent magnet synchronous generators. The multi-phase wind turbines are integrated into the high-voltage direct-current (DC) grid via three-phase bridge uncontrolled rectifiers, isolated DC/DC converters, and modular multilevel converters (MMCs). Specifically, an average current reference value of the three-phase bridge uncontrolled rectifiers is obtained by maximum power point tracking (MPPT) control based on an outer speed loop. Then, the current reference values of each set of three-phase bridge uncontrolled rectifiers are reconstructed according to the working state of the converter for the output power balance of the normal phase. The aim is to ensure that overcurrent does not occur in the fault phase, achieve fault-tolerant control of the system, and thereby improve reliability. Finally, the wind turbine is connected to the DC grid via the single bridge arm of the MMC to reduce the complexity of the converter. With 18-phase wind turbines as an example, a Matlab/Simulink simulation model is built to verify the effectiveness of the proposed topology and fault-tolerant control strategy.

Key words: multi-phase wind turbine, wind power generation, fault-tolerant control strategy, modular multilevel converter, DC/DC converter
