摘要
Aiming at the problem of power device open circuit fault diagnosis of T-type inverter topology active power filter(APF), a fault diagnosis method based on voltage and current residuals is proposed. Analyze the mathematical model of the T-type three-level active power filter and the fault characteristics of power devices at different locations, extract the residual value of the inverter command voltage and output voltage, and the residual value of the inverter command current and output current, and calculate the period average value, and normalize the current residuals, as the basis for fault diagnosis of power devices. Meanwhile, based on the extracted voltage and current residuals of the T-type three-level inverter, a complete and reliable fault determination and faulty power device location determination method was given, and the location of the fault tube was locked by 4 criteria. This method is suitable for APF that adopts model predictive control strategy (MPC) as current tracking control method, and has a wide range of applications. Finally, a simulation model and an experimental platform were built to verify the proposed fault diagnosis method. Simulation and experimental results prove the effectiveness of the fault diagnosis method. © 2022, Harbin University of Science and Technology Publication. All right reserved.
