Mmc Type Power Electronic Transformer Operation Reliability Composite Control Method

In the rapid development of power equipment today, the use of scientific and technological means to make transformers better development has made a trend, in order to more adapt to today's development, create high-efficiency transformers, so that transformer reliability improvement, MMC type power electronic transformers followed. In the operation of MMC type power electronic transformers, the transformer realizes the efficient conversion and transportation of electric energy by periodically storing and outputting electrical energy. The basic control strategy cannot accurately analyze the control problems in the operation of MMC power electronic transformers. Therefore, a composite control method is proposed for reliability analysis. Firstly, the composite control method is used to operate the MMC type power electronic transformer, and the indicators are divided according to the reliability requirements to reduce the interference factors in the reliability. Then, the composite control method is used to run the MMC power electronic transformer to form a reliability scheme and comprehensively analyze the reliability results. The research chart shows that the reliability of the composite control method for the operation of MMC power electronic transformers is better than that of the basic control strategy under certain control standards.
