燃蒸联合循环单轴发电机布置的启发

从供应世界电力市场的GE公司、MITHUBISHI公司、SIEMENTS公司和ALSTON公司等最新燃-蒸联合循环发电机组发电机单轴布置的经验数据出发,对于一体化全电力推进船用联合动力装置做原动机模块的方案进行了初步的论证,探讨了基于联合动力装置的原动机模块的可行性,并给出了公布的两艘美国舰船和一艘英国航空母舰全电力推进方案的改进比较,得到了一些有意义的看法.综合各种情况,单一发电机比同功率的两台发电机在重量上节约了10%以上,所以这种方案使发电机的数目减少一半,占地面积减少10%以上,重量减轻,相关设备大为简化,同时提高了系统的可靠性和可维护性.

Edification from a Single-shaft Layout of Gas-steam Combined Cycle Power Generators

Proceeding from the empirical data of various single-shaft layouts of latest gas-steam combined cycle power generator units supplied by GE,Mitsubishi,Siemens and Alstom company etc.for the world power markets,a preliminary argumentation was conducted of a version in which an IFEP(integrated full electric propulsion) marine combined power plant was used as a primer mover module.Moreover,the feasibility of the module in question based on a combined power plant was investigated and the improvement for full electric propulsion versions published for two warships of USA and one CVN(carrier vessel nuclear) warship of Great Britain was compared with some meaningful viewpoints being obtained.Summing up various circumstances,the authors have concluded that the use of a single generator can reduce the total weight by over 10% compared with the use of two generator sets having the same power output.The version thus obtained can reduce the number of generators by one half and decrease the land area occupied by over 10%,resulting in weight reduction and significant simplification of relevant equipment items.In the meantime,the reliability and maintainability of the system can be improved.
