Power hardware in loop doubly fed induction generator simulation system

Abstract

Based on the idea of model design and development（MBD）, doubly fed induction generator grid simulation system which used power hardware in loop(PHIL) was designed. The turbine system was simulated by the up computer，speed acquisition card，frequency converter and asynchronous motor. The actual DFIG was controlled by back to back doubly PWM converter. The dual controller was applied to control the converter. The NI controller is used to execute PWM algorithm. The auxiliary controller uses TI-28335 DSP to execute a general control program.Their code can be generated by simulation model directly.The output control quantity can be selected according to the experimental requirements.The system can complete the study of a variety of complex working conditions and generate code from Simulink model to controller. So the system can realize complex control algorithm faster and improve the efficiency of scientific research and reduce the cost of testing.
