1.With the enormons increase of electrical power loads on board ships.the old D.C.system is very difficult to meet the challenge,the trend is toward the development of A.C.system. 2.A.C.System is not only economical in generating and distribution,hut also made possible the application of squirrel cage motor,which is simplest, cheapest and most rugged rotating electrical machine obtainable. 3.The variable speed characteristics of A.C.motors is inferior to D.C. motors.particularly as applied to cargo winches. 4.A.C.is specially suitable for large power installations.As the installed generating capacity exceeds 1000 kw.,A.C.is definitely superior to D.C.As the generating capacity is under 1000 kw.,the choice is dependent on usage,for passenger ships,tankers,inland vessels and harbour crafts,where there is little need for variable speed.the superiority of A.C.is quite noticable,for eargo ships, where the electrical load is mainly cargo winches,the advantage is not so noticable. 5.Considering the development of large capacity semi-conductor rectifiers. A.C.and D.C.in the future are not so distinctively different from each other,but may be under a unified system. 6.The author suggests immediate research and experiment works directed to the subject of application of A.C.to ships,and recommends installation of various systems on same type of ships to obtain direct comparisons,and conclusions to be drawn.

1.由于船舶需用之电量急剧增加,旧有之直流系统难以满足需要。发展的趋向为使用交流电。2.交流系统不但在发电及输配电方面经济合算,并且使使用鼠笼式电动机成为可能。鼠笼式电动机为所有旋转电机中最简单、价廉、坚固之电机。3.交流电动机之变速特性较直流电动机为差,特别在使用于起货机时。4.对于大容量装置,交流系统特别适宜。如果发电机容量大于1000千瓦,交流肯定的比直流有利。如果发电机容量小于1000千瓦,应视用途而定。对客船、运油船、内河船舶和港湾作业船等,变速的需要不大,交流显然有利。在以起货机作为主要负荷的货船上,交流电的优点不显著。5.考虑到大容量半导体整流器的发展,将来的情况将是直流和交流的分界不是截然不同的,而是可能在一个体系之下的。6.作者建议对交流电应用到船舶上的问题立即进行研究和试验,并建议在同一型式船舶上装置不同系统,以获得经验,得出结论。
