摘要
由于应急发电机容量的限制,在启动大功率应急负载时对电网的冲击较为突出。为从理论层面解决该问题,论述选择大功率应急负载启动方式时需考虑的问题,并通过实际案例详细介绍如何选择启动方式,供船舶电气设计人员参考。合理选择大功率应急负载启动方式,不仅能有效保证船舶安全运行,而且能避免因应急发电机容量增加而导致船舶造价上升。
The capacity restriction of emergency generator makes the impact caused by the startup of bulk-power emergency load on power grid particularly prominent.In order to solve the problem from the theoretical perspective,this paper discusses the issues to be considered in selecting the start method of bulk-power emergency consumers.A real case is taken to introduce how to choose the start method to provide reference for the marine electrical designers.The proper selection of start method of bulk-power emergency load can not only guarantee the safe operation of the ship,but also avoid the increase of ship construction cost due to the increase of emergency generator capacity.
