摘要
鼓风机是发电厂锅炉的重要辅助设备,采用高压变频器对鼓风机进行变频调速能够极大提高效率,减小损耗。对一种基于MMC的高压变频器结构进行研究,提出了相应的控制策略,并对提出的控制策略进行了仿真和实验研究,仿真和实验结果验证了所提出控制策略的正确性和实用性。
The blower is an important auxiliary equipment of power plant boiler. The frequency conversion speed regulation of blower is greatly improved by using high voltage inverter,which can greatly improve the efficiency and reduce the loss. The high voltage inverter based on MMC is studied,the corresponding control strategy is put forward,and the proposed control strategy is verified by simulation. The simulation results verify the correctness and practicability of the proposed control strategy.
