Abstract : A wind power generation system based on 1MS320LF2407A and TMS320VC33 dual DSPs was developed. Based on the analysis of the system's control method, a vector control system model with grid-side voltage orientation and rotor-side stator magnetic field orientation for the AC-DC-AC frequency converter was established. Experimental studies were conducted on the system's variable-speed constant-frequency control and grid-connected control technologies. The results show that the system can achieve soft grid connection within the generator's allowable speed range, and the input and output active and reactive power can be independently adjusted, making it suitable for megawatt-level wind power generation systems.

In recent years, wind power generation technology has received widespread attention and importance from scholars worldwide. Variable-speed constant-frequency power generation is currently the development direction of wind power generation technology. Doubly fed induction generator (DFIG) wind power systems are a suitable variable-speed constant-frequency (VFD) solution. The stator windings of the generator are connected to the industrial frequency grid, and VFD control is achieved by changing the frequency, amplitude, phase, and phase sequence of the power supply to the rotor windings. Since the inverter in this solution only transmits slip power, its capacity can be significantly reduced. Currently, the inverters used in DFIG VFD wind power systems are typically AC-AC or AC-DC-AC inverters. AC-AC inverters have high output voltage harmonics, low input power factor, and require a large number of power components; therefore, they have been largely replaced by voltage-type AC-DC-AC inverters. Recent literature has also researched the application of matrix converters in DFIG wind power systems; however, the number of components used in matrix converters is higher than in AC-DC-AC inverters, the components have higher withstand voltages, and their input-output control is not decoupled. These drawbacks limit their application in wind power generation to some extent. This paper presents a voltage-source AC-DC-AC doubly-fed wind power generation system based on dual DSPs, developed according to the characteristics of wind power generation. The system employs voltage-oriented vector control on the grid side of the inverter and stator field-oriented vector control on the rotor side. Experimental results show that the system has bidirectional power flow capability, its input and output power factors can be independently adjusted, it has low input and output harmonics, and it can operate over a wide range, enabling high-quality power generation from wind energy and other unstable energy sources.
