摘要
低电压故障穿越技术是电力推进船舶的重要功能。本文以中海油某型双燃料电推PSV为例,通过分析不同短路点,归纳短路试验试验点选取方法。随后,针对欠压引起的非故障母排发电机电压超调,指出需通过励磁调节器的正确配置予以限制。最后,对各关联系统的设计原则进行了总结。依照本文方法,可有效避免短路故障造成的全船失电。
The low voltage ride through strategy is an important function of electrical propulsion marine.This paper analyses different Short Points by a dual fuel PSV of COSL for example to conclude the selective method of short-circuit test. Later, points out the AVR should be set suitably to reduce the overshoot caused by under voltage in non-fault busbar. In addition, concludes the design principles of coherent system.Electric blackout caused by short circuit could be avoid by the principles in this paper.
