The role of inverters in the interface between wind power generation systems and power grids

As the interface between wind power generation systems and the power grid, the inverter plays a crucial role in power conversion and control. It is also one of the most vulnerable components in the system, making it prone to failures. The quality of power supplied to the grid or load largely depends on the performance of the inverter. Therefore, ensuring stable grid operation and high power quality requires effective fault diagnosis of the inverter. In recent years, research on inverter fault diagnosis has become a major focus for scholars worldwide. The TMS320F28335 DSP, a 32-bit floating-point digital control processor from Texas Instruments, offers high performance with a main frequency of 150 MHz, rich peripherals, large memory capacity, and fast processing speed. It has been widely used as the core controller in transformer intelligent control and fault detection systems. The inverter system is a complex hybrid system that involves multiple interdependent components. Traditional programming methods for DSP systems are time-consuming and labor-intensive. To address this, MathWorks and TI introduced the TSP (TI Support Package) tool, which allows modeling, simulation, code generation, and debugging within the Simulink environment, significantly improving development efficiency. This paper explores the use of automatic code generation technology to streamline the development of inverter systems. By leveraging tools like Embedded Coder and the TSP toolbox, developers can build system models, simulate them, and automatically generate embedded C code. This approach reduces development time, lowers costs, and improves overall efficiency. The development process based on code generation includes several key steps: defining system requirements, building a simulation model in Simulink, configuring parameters and algorithms, simulating the model, and validating results. Once the simulation is complete, the target environment is configured, and the code is generated and tested on hardware. A three-level inverter is a common topology used in power electronics, offering advantages such as reduced voltage stress and improved output waveform quality compared to traditional two-level inverters. The modulation algorithm used in three-level inverters produces 12 trigger pulses, which are essential for controlling IGBTs and generating the desired AC output. To simplify the coding process for three-level PWM control, an automatic code generation model was developed. Using Simulink and the TSP toolbox, the model was built and configured to generate the necessary control signals. This approach eliminates the need for manual coding, reducing errors and saving time. After the model was successfully compiled, the generated code was downloaded to the DSP chip via CCS. Testing on the physical system confirmed that the control pulses and output waveforms matched the simulation results, validating the effectiveness of the method. In conclusion, this study demonstrates that using code generation technology for inverter systems significantly improves development efficiency, reduces error rates, and provides a practical solution for implementing intelligent control and fault diagnosis algorithms. The approach is simple, efficient, and highly applicable to real-world applications.
