摘要：采用单元级联主回路拓扑结构的四象限变频器装置，具有能量回馈功能。可实现汽轮机不同转速下的发电工况。它相比传统的汽轮机发电具有转速可调、无扰并网、发电控制精准、操作方便、可靠性高等优点，具有很高的推广价值。 关键词：单元级联；四象限；无扰并网；汽轮机；可调转速 Abstract: Four quadrant frequency converter, which adopts cells cascaded main circuit topology, has energy feedback function. Power generation conditions at different speeds of steam turbines can be realized. It compared[登陆后可查看全文]
